    IIJ to List on the Mothers market of the Tokyo Stock Exchange


    TOKYO--(BUSINESS WIRE)--May 27, 2005--Internet Initiative Japan
Inc. (IIJ, NASDAQ:IIJI), one of Japan's leading Internet access and
comprehensive network solutions providers, today announced that it
received notification that the Tokyo Stock Exchange has approved the
listing of its shares of common stock on the Mothers market of the
Tokyo Stock Exchange. IIJ believes that listing on the Mothers market
will further expand its business by strengthening its presence in
Japan and by providing additional financing options. The expected
listing date is June 23, 2005.
    In connection with the Mothers listing, IIJ plans to issue 2,500
new shares and two shareholders, NIF Ventures Co., Ltd. and JAFCO Co.,
Ltd., which are Japanese venture capital firms, plan to sell 900
existing shares in an underwritten public offering in Japan. In
addition, the lead underwriter will be provided by the selling
shareholders with the option to purchase up to additional 500 shares
to cover over-allotments, if any. The newly issued shares will
comprise approximately 6.1% of IIJ's total shares after giving effect
to the issuance. IIJ plans to use the proceeds from the issuance of
the new shares for ongoing capital investment in operations and
research and development.
    The offer price for the public offering in Japan will be based on
the closing price of IIJ's American Depositary Receipts on the NASDAQ
National market on the date prior to the pricing date subject to a
discount determined in accordance with market demand. Pricing is
expected to occur on a date between June 14 and June 16.
    Any shares sold in connection with the proposed offering have not
been and will not be registered under the U.S. Securities Exchange Act
of 1933, as amended (the "Securities Act") and may not be offered or
sold in the United States absent registration under the Securities Act
or an applicable exemption from the registration requirements of the
Securities Act.

    Statements made in this press release regarding IIJ's or
management's intentions, beliefs, expectations, or predictions for the
future are forward-looking statements that are based on IIJ's and
managements' current expectations, assumptions, estimates and
projections about its business and the industry. These forward-looking
statements are subject to various risks, uncertainties and other
factors that could cause IIJ's actual results to differ materially
from those contained in any forward-looking statement.

    Notes:

    1. Both unaudited consolidated and non-consolidated financial
results for the fiscal year ended March 31, 2005 have not been audited
in accordance to the rule in Article 193-2 of Securities and Exchange
Law (in Japan).
    2. Basic and diluted net income (loss) per share in the
consolidated financial results for the fiscal year ended March 31,
2004 and March 31, 2005 are computed using the weighted-average number
of shares of common stock outstanding during the fiscal year. Basic
and diluted net income (loss) per share in the non-consolidated
financial results for the fiscal year ended March 31, 2004 and March
31, 2005 are computed using the weighted-average number of shares of
common stock in issuance during the fiscal year.
    3. Consolidated and non-consolidated basic and diluted net income
per share for the period ending September 30, 2005 and the fiscal year
ending March 31, 2006 is calculated assuming that 40,860 shares will
be issued as of period end, including the 2,500 shares proposed to be
issued in connection with the contemplated listing.
    4. Statements made in this press release regarding IIJ's or
management's intentions, beliefs, expectations, or predictions for the
future are forward-looking statements that are based on IIJ's and
managements' current expectations, assumptions, estimated and
projections about its business and the industry. These forward
-looking statements, such as targeted financial results, are subject
to various risks, uncertainties and other factors that could cause
IIJ's actual results to differ materially from those contained in any
looking-forward statement. These risks, uncertainties and other
factors include: IIJ's ability to maintain and increase revenues from
higher margin services such as system integration and value-added
services; the possibility that revenues from connectivity services may
decline substantially as a result of competition and other factors;
the ability to compete in a rapidly evolving and competitive
marketplace; the impact on IIJ's profits of fluctuations in costs such
as backbone costs and subcontractor costs; the impact on IIJ's profits
of fluctuations in the price of available-for-sale securities; the
impact of technological changes in its industry; IIJ's ability to
raise additional capital to cover its indebtedness; the possibility
that NTT, IIJ's largest shareholder, may decide to exercise
substantial influence over IIJ; and other risks referred to from time
to time in IIJ's filings on Form 20-F of its annual report and other
filings with the United States Securities and Exchange Commission.

                                       The offer price for the general public offering (offer
                                       price) will be determined by the method as prescribed in
                                       Article 7-2 of No.14 Rules of Fair Practice of the Japan
                                       Securities Dealers Association. The offer price will be
                                       determined in consideration of demand conditions and
                                       will be based on the closing price of the Company's
                                       American Depository Receipts ("ADR") on the U.S. NASDAQ
                                       National Market on the day before the Pricing Date. In
                                       the event that there is no closing price on that date,
                                       the closing price on the nearest preceding date will be
                                       used. The provisional terms are as follows. The ADR
                                       closing price will be multiplied by 2,000, the stock-ADR
                                       conversion rate. The resulting figure will be converted
                                       to yen using the Bank of Tokyo-Mitsubishi's telegraphic
                                       transfer middle rate on the Pricing Date. That figure
                                       will then be multiplied by a number from 0.90 to 1.00.
                                       Any remainders of less than one yen will be truncated.

      (*) Shares sold through over-allotment



The sale of shares through over-allotment is an additional offering that
may be implemented by Daiwa Securities SMBC in accordance with investor demand.
Accordingly, the number of shares to be offered through over-allotment is shown
as the maximum number of shares, and it is possible that the number of shares
will be reduced or that the offering via allotment will be eliminated based on
demand conditions.

The IIJ common stock that will be sold through over-allotment will be
borrowed by Daiwa Securities SMBC from IIJ shareholders for the purpose of the
sale through over- allotment.

In the connection therewith, Daiwa Securities SMBC will be granted by IIJ
shareholders an option (hereafter, "green-shoe option") to additionally acquire
a maximum of 500 shares. The exercise period of the green shoe option will end
July 15, 2005. Daiwa Securities SMBC will return the shares borrowed from IIJ
shareholders using shares acquired through the exercise of the green-shoe
option, the syndicate cover transaction described below, or both.

Also, during the period from June 23 to July 15, 2005 (hereafter, syndicate
cover transaction period), Daiwa Securities SMBC may purchase shares of IIJ's
stock on the Tokyo Stock Exchange (hereafter, syndicate cover transaction), for
the purpose of returning shares borrowed from IIJ shareholders, with an upper
limit of the number of shares offered through over-allotment.

Daiwa Securities SMBC does not plan to exercise the green-shoe option for
the number of shares in the syndicate cover transaction. In addition, during the
syndicate cover transaction period, Daiwa Securities SMBC may decide not to
conduct the syndicate cover transaction or to conclude the transaction without
purchasing the maximum number of shares.




     
Note:    This notice is intended as a press release for a general announcement concerning
         IIJ's issuance and sale of new shares. It is not intended as a solicitation of
         investment. Any investments should be made at the discretion of individual
         investors after reading IIJ's prospectus on the issuance and sale of shares and
         any revisions thereto.
         The shares subject to the aforementioned new share offering and secondary offering
         have not been and will not be registered under the United States Securities Act
         of 1933, as amended ("the Securities Act") and may not be offered or sold in the
         United States or to US persons absent registration under the Securities Act or an

3. Use of the Proceeds from the Issue

The total proceeds of approximately 1,880,000 thousand yen will be

4. Distribution of Profits to Shareholders

     (1) Basic policy on the distribution of profits

      The Company has not paid dividends in the past years. The Company
      considers the payment of dividends to shareholders to be an important
      management issue. However, at the current time, the Company's policy
      is to give priority to securing funds to strengthen its financial
      position and to use for operational development. Therefore, there is
      possibility that the Company would not pay dividends for a while.

    (2) Specific plans to increase distribution of profits to shareholders in
        the future.

    The Company does not have any specific fixed plans at the current time.

5. Share Sales Policy

   With regard to sales of the new shares, considering such factors as the
   requirements of Tokyo Stock Exchange regulations related to meeting
   the required level of the number of shareholders and obtaining the
   proper level of distribution of the shares after listing, there may be
   sales made to investors that did not report their requirements for
   shares.

   With regard to sales to investors that reported their intention to purchase
   the new shares, the underwriters will follow their respective company
   regulations and procedures, and choose from the ranks of investors
   that reported their intention to purchase the new shares at or above
   the offering price to carry out such sales, taking into consideration,
   as a general principle, such factors as the degree of the investors'
   experience, their knowledge of securities investment, and their
   investing policies.

   Concerning sales to investors that did not report requirements for shares,
   the underwriters will make their decisions based on their respective
   company rules and regulations and, as a general principle, will
   consider such factors as knowledge and experience in securities
   investment, investing policies, and transactions with underwriters
   when making their decisions concerning such sales.

   Note:  In the above section "4. Distribution of Profits to Shareholders,"
          the section that refers to future distribution of profits does not
          guarantee a certain level of dividends and is based on current
          forecasts.


  The above represents a translation of the original version in the Japanese
  language.

Notes:


1. Comparisons with the third quarter of the previous fiscal year have not been
   included because the Company began quarterly disclosure of consolidated
   results in the format required by TSE rules from the third quarter of the
   fiscal year ended March 31, 2005.


2. The Company provides customers with a comprehensive range of connectivity
   services, value-added services, systems integration, and equipment sales as a
   combination. The Company does not classify results by segment because it
   implements combined marketing, advertising, and sales management of such
   services and does not regard them as separate segments.


3. In cash flows, the effect of exchange rate changes on cash and cash
   equivalent was a negative YEN 43 million in the previous fiscal year, ended
   March 31, 2004, and a positive YEN 18 million in the third quarter of the
   fiscal year ended March 31, 2005.


2. Performance Overview (from April 1, to December 31, 2004)


(1) Performance Overview


   In the third quarter of the fiscal year ended March 31, 2005, trends in
Japan's economy were favorable. Although there were such uncertain factors as
rising crude oil prices, consumer spending rose modestly, exports and industrial
production were up, and corporate earnings were favorable.


   In the market for data communications, including the Internet, demand for
reliable systems with respect to information management and security is growing
in line with the establishment among corporations and government agencies of
networks that enable efficient usage of information.


   In such an operating environment, during the third quarter of the fiscal year
ended March 31, 2005, the Company focused on offering total solutions that
provide customers with services comprehensively. Also, the Company focused
efforts on curbing costs and raising capacity utilization.


   In the third quarter of the fiscal year ended March 31, 2005, the Company
recorded revenues of YEN 29,448 million, operating income of YEN 591 million,
income before income tax expense of YEN 763 million, and net income of YEN 650
million.

                                       2



   The Company's performance by service area was as follows.

a.       Connectivity and Value-Added Services


   In dedicated access services, the Company focused on the construction and
provision of network systems using Internet VPN services for corporate customers
with multiple operational sites. Internet VPN services, which use the relatively
lower-priced Flet's network for access lines, offer a low-cost alternative to
the network systems that use conventional dedicated lines or frame relay lines.
Contracts for dedicated access services increased significantly and contracted
bandwidth per customer rose. Meanwhile, relatively higher-priced IP services saw
the cancellation of certain large contracts and some customers shifted to new,
inexpensive packages that use the Flet's network for access lines. As a result
of such factors, revenues totaled YEN 8,531 million.


   In dial-up access services, sales of services for individuals such as IIJ4U
declined, and revenues amounted to YEN 2,218 million.


   In value-added services, with the growing corporate outsourcing needs, sales
of services related to security, network outsourcing, server outsourcing, and
data centers were up. Consequently, revenues from value-added services stood at
YEN 3,682 million.


   In other services, the Company leased network equipment, offered customer
support through consolidated subsidiary Net Care, Inc., and sold Wide-area
Ethernet services. As a result, revenues were YEN 2,190 million.


   As a result  of the  above,  revenues  from  connectivity  and  value-added
services totaled YEN 16,623 million.  The cost of revenues from connectivity and
value-added   services   declined   mainly  due  to  reduced   backbone   costs.
Consequently, gross margin was YEN 2,158 million, and the gross margin ratio for
connectivity and value-added services was 13.0%.


b. Systems Integration


   In the third quarter of the fiscal year ended March 31, 2005,  the revenues
from systems  integration was YEN 10,501 million.  Of that amount,  the revenues
from the services likely to generate monthly ongoing  revenues,  such as network
operation and maintenance, was YEN 5,690 million.


   Systems integration accounted for gross margin of YEN 2,332 million, and the
gross margin ratio was 22.2% mainly due to increased revenues from operation and
consulting.


c. Equipment Sales


   In the third  quarter of the fiscal  year ended March 31,  2005,  equipment
sales  generated  revenues of YEN 2,322 million,  which were related to sales of
network equipment and equipment developed in-house by IIJ, such as SEIL routers,
to customers.  Gross margin amounted to YEN 174 million,  while the gross margin
ratio was 7.5%.


(2) Cash Flows


   Cash and cash equivalent at the end of the third quarter of the fiscal year
ended March 31, 2005 totaled YEN 12,158 million.


(Net cash provided by operating activities)


   Net cash provided by operating activities was YEN 2,697 million.


(Net cash provided by investing activities)


   Net cash  provided by  investing  activities  amounted to YEN 127  million.
Proceeds from sale of other investments such as available-for-sale securities of
YEN 967 million offset purchase of property and equipment of YEN 480 million and
acquisition of business of YEN 371 million.


(Net cash used in financing activities)


   Net cash used in financing activities totaled YEN 2,968 million. repayments
of long-term and short-term borrowings of YEN 3,269 million,  principal payments
under capital  leases of YEN 2,114  million,  and the  repurchase of convertible
notes  of YEN 745  million  exceeded  proceeds  from  long-term  borrowings  and
proceeds from a securities loan agreement of YEN 2,972 million.

Note: The above performance projections are based on the information that was
available to the Company on the date of release of this document. These
performance projections have been prepared based certain assumptions and contain
risks and uncertainties. Further, the Company's actual performance could differ
significantly from projected figures due to a variety of factors including
changes in operating conditions and market trends. At this time, the main
foreseeable risks and uncertainties facing the Company include: 1) a decline in
the willingness of corporations to invest in systems as a result of changes in
the economic situation such as sluggishness in Japan's economy; 2) a reduction
in the reliability of the Company's services resulting from the discontinuance
of services due to various events; 3) changes in the procurement procedures or
costs for such items as outsourcing or backbone lines required to provide
services; 4) further competition or price competition with competitors; 5) an
increase in the seasonal fluctuation of quarterly results; and 6) the effect of
changes in the market value of stockholdings on business performance or
financial position. With respect to these risks and uncertainties, please refer
to the Company's securities registration statements and other financial
documents, which the Company plans to release in adherence with Japan's laws and
disclosure regulations, and to its Form 20-F and other documents that the
Company files with the United States Securities and Exchange Commission in
adherence with securities laws of the United States of America.

Basis of Presenting Consolidated Financial Statements for the Third Quarter
of the Fiscal Year Ended March 31, 2005


1. The Terminology, Form, and Preparation Methods for Consolidated Financial
Statements for the Third Quarter of the Fiscal Year Ended March 31, 2005


The financial statements for the third quarter of the fiscal year ended March
31, 2005, have been prepared in accordance with the provisions of article 81
"provisions for the terminology, form, and preparation methods for interim
consolidated financial statements" (Ministry of Finance, ordinance No. 24,
1999), and based on the accounting treatment principles and procedures and
disclosure methods required in relation to the issuance of American Depository
Receipts ("ADRs") (primarily generally accepted accounting principles in the
United States of America ("U.S. GAAP"), including Accounting Research Bulletins
("ARB"), Accounting Principles Board ("APB") Opinions, Statement of Financial
Accounting Standards ("SFAS"), and related interpretation guidelines).


IIJ registered the sale of ADRs with the Securities and Exchange Commission
("SEC") of the United States of America under the Securities and Exchange Act of
1933, as amended and registered the quotation of the ADRs on the NASDAQ National
Market of the United States of America in August 1999. Further, in accordance
with Rule 13 of the U.S. Securities Exchange Act of 1934, as amended, IIJ
regularly files with the SEC an annual report on Form 20-F which includes
consolidated financial statements prepared in accordance with U.S. GAAP.


2. Main Differences from Preparation in Accordance with Provisions and
Principles for Interim Consolidated Financial Statements


The main differences between consolidated financial statements for the third
quarter of the fiscal year ended March 31, 2005 prepared in accordance with U.S
accounting standards and those prepared in accordance with Japan's provisions
and principles for interim consolidated financial statements and the effect on
important monetary items and on income before income tax expense in the third
quarter of the fiscal year ended March 31, 2005 are given below.


(1) Differences Regarding the Composition of Consolidated Financial Statements


Consolidated financial statements have been prepared based on accounting
standards of the United States of America comprise consolidated balance sheets,
consolidated statements of operations, consolidated statements of shareholders'
equity, consolidated statements of cash flows, and notes to consolidated
financial statements.


(2) Differences Regarding Disclosure in Consolidated Financial Statements


In consolidated statements of operations, equity in net income of equity method
investees is shown as a separate item after income from operations before income
tax expense.


(3) Differences Regarding Accounting Treatment Standards


a. Income taxes


Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards (SFAS) No. 109. Changes in the deferred income tax asset
valuation allowance that relate to the tax effect of unrealized gains and losses
on available-for-sale securities have been recorded as a separate component of
other comprehensive income.


b. Accounting treatment of lease transactions


The Company accounts for significant lease transaction agreements that fulfill
the requirements for capitalized leases as stipulated by SFAS No. 13, in
accordance with SFAS. As a result, finance lease transactions, other than those
that recognize transfer of ownership to the lessee, are treated as purchases. In
the third quarter of the fiscal year ended March 31, 2005, this accounting
treatment of lease transactions resulted in a YEN 32,153 thousand reduction in
income from operations before income tax expense.


c. Securities


The Company accounts for securities received as the result of exchanges
associated with mergers with other companies using the fair value based on
Accounting Principles Board (APB) Opinion No. 29. In the third quarter of the
fiscal year ended March 31, 2005, this accounting treatment resulted in a
YEN 35,450 thousand increase in income from operations before income tax
expense.


                                       16


d. Bond issuance cost


Bond issuance cost is recorded in other assets and amortized over the bond
redemption period. In the third quarter of the fiscal year ended March 31, 2005,
this accounting treatment resulted in a YEN 60,180 thousand reduction in income
from operations before income tax expense.


e. Stock issuance cost


Stock issuance cost is accounted for as expenses related to capital transactions
and deducted from additional paid-in capital. In the third quarter of the fiscal
year ended March 31, 2005, this accounting treatment resulted in a YEN 33,263
thousand increase in income from operations before income tax expense.


f. Retirement benefit accounting


Unfunded retirement  benefits and  noncontributory  defined benefit pension
plans are accounted for in accordance  with SFAS No. 87. In the third quarter of
the fiscal year ended March 31, 2005,  this accounting  treatment  resulted in a
YEN 1,758  thousand  reduction  in income  from  operations  before  income  tax
expense.


g. Comprehensive income


Comprehensive income is accounted for in accordance with SFAS No. 130 "reporting
comprehensive income." SFAS requires additional disclosure of information in
consolidated financial statements. In the third quarter of the fiscal year ended
March 31, 2005, this accounting treatment did not result in any change in income
before income from operations before income tax expense.

Notes to Quarterly Consolidated Financial Statements for the third quarter of
the fiscal year ended March 31, 2005


1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


Internet Initiative Japan Inc. ("IIJ"), a Japanese corporation, was founded in
December 1992 to develop and operate Internet access services and other
Internet-related services and is 31.6 percent owned by Nippon Telegraph and
Telephone Corporation ("NTT") and its subsidiary, NTT Communications Corporation
as of December 31, 2004. IIJ and consolidated subsidiaries (collectively, the
"Company") provide connectivity services throughout Japan and into the United
States of America and value-added services. Also, the Company provides Internet
access services into the rest of Asia through a direct connection to the A-Bone,
an Internet backbone that is operated by IIJ's equity method investee, Asia
Internet Holding Co., Ltd. The Company's operations include systems integration
and equipment sales, which mainly comprise consulting, design, development,
construction, operation, and maintenance for Internet-related systems; equipment
sales in relation to equipment procurement for the construction of systems; and
other Internet-related services.


The Company manages its business and measures results based on a single
Internet-related services industry segment including revenues from systems
integration. Substantially, all revenues are from customers operating in Japan.


The accompanying consolidated financial statements for the third quarter of the
fiscal year ended March 31, 2005 have been prepared on a going-concern basis,
which contemplates the realization of assets and the satisfaction of liabilities
in the normal course of business. The Company recorded operating income in the
third quarter of the fiscal year ended March 31, 2005, however, the Company has
incurred operating losses and net losses in each of the past six fiscal years,
with the exception of operating income recorded in the year ended March 31,
2002.


As of December 31, 2004,  the Company had  indebtedness  of YEN  28,454,898
thousand including  convertible notes of YEN 11,088,000  thousand due March 2005
and negative working capital of YEN 6,532,986 thousand.  Although the Company is
considering various alternatives to increase revenues and improve profitability,
there can be no assurance  that these  actions and efforts  will be  successful.
However,  the  management  believes that as of December 31, 2004,  the Company's
cash and cash  equivalents  of YEN  12,158,790  thousand and  available-for-sale
securities of YEN 10,006,681  thousand,  including  common stock investment in a
single Japanese  company of YEN 8,735,616  thousand,  cash provided by operating
activities,  and  continuing  bank  financing  should  provide the Company  with
sufficient  resources  to redeem the  convertible  notes and meet its other near
term cash requirements.


Certain Significant Risks and Uncertainties
-------------------------------------------


The Company participates in a dynamic high technology industry and believes that
changes in any of the following areas could have a material adverse effect on
the Company's future financial position, results of operations or cash flows:
advances and trends in new technologies and industry standards; competitive
pressures in the form of new products or price reductions on current products;
changes in product mix and overall demand for products offered by the Company;
changes in certain strategic relationships or customer relationship; litigation
or claims against the Company based on intellectual property, product,
regulatory or other factors; risk associated with change in domestic and
international economic and/or political conditions or regulations; and
fluctuation in stock price of available-for-sale securities which the Company
owns.


The Company relies on telecommunications carriers, including NTT Communications
Corporation ("NTT Communications") for a significant portion of network
backbone, and Nippon Telegraph and Telephone East Corporation, Nippon Telegraph
and Telephone West Corporation, electric power companies and their affiliates
for local connections to customers, and third-party suppliers for the use of
hardware components such as routers and servers. The Company believes that its
use of multiple carriers, suppliers, and alternative facilities significantly
mitigates concentrations of credit risk. However, any disruption of
telecommunication services or the inability of suppliers to deliver hardware
components on a timely basis or to develop alternative sources of components
could have an adverse effect on operating results.


Financial instruments that potentially subject the Company to concentrations of
credit risk consist principally of cash investments, accounts receivable and
guarantee deposits. The Company's management believes that the risk associated
with accounts receivable is mitigated by the large number of customers
comprising its customer base.


Summary of Significant Accounting Policies


                                       18


Basis of Presentation
---------------------


IIJ maintains its record in accordance with generally accepted accounting
principles in Japan. Certain adjustment and reclassifications have been
incorporated in the accompanying consolidated financial statements to conform to
generally accepted accounting policies in the United States of America ("U.S.
GAAP"). These adjustments were not recorded in the statutory accounts.


Consolidation
-------------


The consolidated financial statements for the third quarter of the fiscal year
ended March 31, 2005 include the accounts of IIJ and all of its subsidiaries:
Net Care, Inc. ("Net Care"), IIJ Technology Inc. ("IIJ Technology"), IIJ Media
Communications Inc. ("MC"), IIJ Financial Systems, Inc. ("IIJ-FS"), and IIJ
America, Inc. ("IIJ America"), which have third quarters ended December 31,
except for IIJ America. IIJ America's third quarter end is September 30 and such
date was used for purposes of preparing the consolidated financial statements as
it is not practicable for the subsidiary to report its financial results as of
December 31. There were no significant events that occurred during the
intervening period that would require adjustment to or disclosure in the
accompanying consolidated financial statements. Significant intercompany
transactions and balances have been eliminated in consolidation. Investments in
companies over which IIJ has significant influence but not control are accounted
for by the equity method. For other than a temporary decline in the value of
investments in equity method investees below the carrying amount, the investment
is reduced to fair value and an impairment loss is recognized.


Use of Estimates
----------------


The preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and reported amounts of revenues and
expenses during the reporting period. Significant estimates and assumptions used
are primarily in the areas of impairment loss on investment in and advances to
equity method investees, valuation allowances for deferred tax assets, allowance
for doubtful accounts, and estimated lives of fixed assets. Actual results could
differ from those estimates.


Revenue Recognition
-------------------


Revenues from customer connectivity services consist principally of dedicated
Internet access services and dial-up Internet access services. Dedicated
Internet access services represent full-line IP services and standard-level IP
services (T1 Standard and IIJ FiberAccess/F Service). Dial-up Internet access
services are provided to both enterprises and individuals (IIJ4U). The term of
these contracts is one year for dedicated Internet access services and generally
one month for dial-up Internet access services. All these services are billed
and recognized monthly on a straight-line basis.


Value-added service revenues consist principally of sales of various Internet
access-related services such as firewall services. Value-added services also
include monthly fees from data center services such as housing, monitoring, and
security services. Other revenues under connectivity and value-added services
consist principally of call-center customer support and wide-area network
services, which offer connectivity services for the construction of networks
that connect a customer's multiple operational sites. The terms of these
services are generally for one year and revenues are recognized on a
straight-line basis during the service period.


Initial set up fees received in connection with connectivity services and
value-added services are deferred and recognized over the contract period.


Systems integration revenues consist principally of the development of Internet
network systems or design and related maintenance, monitoring, and other
operating services. The period for the development of the systems or designs is
less than one year and revenues are recognized when network systems and
equipment are delivered and accepted by the customer under the completed
contract method. The development of the Internet network systems or design
include multiple element arrangements such as planning, systems design, and
construction services, and equipment and software purchased from third parties.
When the equipment or system is delivered prior to other elements of the
arrangement, revenue is deferred until other service elements are completed and
accepted by the customer. Maintenance, monitoring, and operating service
revenues are recognized ratably over the separate contract period, which is
generally for one year.


Equipment sales represent revenues earned in which the Company acts as principal
in the transaction, takes title to the equipment and has risks and rewards of
ownership while in inventory and are reported gross as the indicators outlined
in the provisions of the Emerging Issues Task Force ("EITF") of the Financial
Accounting Standards Board ("FASB") Issue No. 99-19 "Reporting Revenue Gross as
a Principal versus Net as an Agent" are met.


                                       19


From the third quarter of the fiscal year ended March 31, 2005, the Company
adopted EITF Issue No. 00-21, "Accounting for Revenue Arrangements with Multiple
Deliverables." EITF Issue No. 00-21 addresses certain aspects of the accounting
by a vendor for arrangements under which it will perform multiple
revenue-generating activities with respect to when revenue should be recognized
and how arrangement consideration should be measured. The adoption of EITF Issue
No. 00-21 did not have a material effect on the Company's consolidated financial
position or results of operations.


Cash and Cash Equivalents
-------------------------


Cash and cash equivalents includes time deposit and readily marketable
securities with original maturities of three months or less.


Allowance for Doubtful Accounts
-------------------------------


An allowance for doubtful accounts is established in amounts considered to be
appropriate based primarily upon the Company's past credit loss experience and
an evaluation of potential losses in the receivables outstanding.


Other Investments
-----------------


In accordance with Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," all
marketable equity securities are classified as available-for-sale securities,
which are accounted for at fair value with unrealized gains and losses excluded
from earnings and reported in accumulated other comprehensive income (loss). The
cost of securities sold is determined based on average cost.


The Company reviews the fair value of available-for-sale investments on a
regular basis to determine if the fair value of any individual investment has
declined below its cost and if such decline is other than temporary. If the
decline in value is judged to be other than temporary, the cost basis of the
investment is written down to fair value. Other than temporary declines in value
are determined taking into consideration the extent of decline in fair value,
the length of time that the decline in fair value below cost has existed and
events that might accelerate the recognition of impairment. The resulting
realized loss is included in the consolidated statements of operations in the
period in which the decline was deemed to be other than temporary.


Non-marketable equity and debt securities are carried at cost, however, if the
value of a security has declined and is judged to be other than temporary, the
security is written down to the estimated fair value.


Inventories
-----------


Inventories consist mainly of network equipment purchased for resale and
work-in-process for development of Internet network systems. Network equipment
purchased for resale is stated at the lower of cost, which is determined by the
average-cost method, or market. Work-in-process for development of network
systems is stated at the lower of actual production costs, including overhead
cost, or market. Inventories are reviewed periodically and items considered to
be slow-moving or obsolete are written down to their estimated net realizable
value.


Property and Equipment
----------------------


Property and equipment are recorded at cost. Depreciation and amortization of
property and equipment, including purchased software and capitalized leases, are
computed principally using the straight-line method based on either the
estimated useful lives of assets or the lease period, whichever is shorter.


The useful lives for depreciation and amortization by major asset classes are as
follows:

--------------------------------------------------------------------------------

                                                        Range of Useful Lives
--------------------------------------------------------------------------------

  Data communications, office and other equipment        2 to 15 years

  Leasehold improvements                                 3 to 15 years

                                       20



  Purchased software                                           5 years

  Capitalized leases                                      4 to 7 years
--------------------------------------------------------------------------------

Impairment of Long-Lived Assets
-------------------------------


Long-lived assets consist principally of property and equipment, including those
items leased under capital leases. On April 1, 2002, the Company adopted SFAS
No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which
addresses financial accounting and reporting for the impairment or disposal of
long-lived assets. The adoption of SFAS No. 144 did not have a material effect
on the Company's consolidated financial position and results of operations.
Prior to the adoption of SFAS No. 144, the Company accounted for long-lived
assets in accordance with SFAS No. 121, "Accounting for Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." The Company evaluates the
impairment of long-lived assets whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. There was
no impairment loss for long-lived assets in the third quarter of the fiscal year
ended March 31, 2005.


Goodwill and Intangible Assets
------------------------------


On April 1, 2002, the Company adopted SFAS No. 142, "Goodwill and Other
Intangible Assets." Under the statement, goodwill (including equity-method
goodwill) and intangible assets that are deemed to have indefinite useful lives
are not amortized, but are subject to impairment testing. Impairment testing is
required to be performed at adoption and annually or more frequently if events
or changes in circumstances indicate that the asset might be impaired. The
Company selected March 31 as its annual impairment testing date. Upon the
adoption of the statement, the Company ceased the amortization of goodwill
recorded in past business combinations and acquisitions. Additionally, the
Company ceased the amortization of intangible assets that are deemed to have
indefinite lives. As required by SFAS No. 142, the Company also reassessed the
useful lives and the classification of its identifiable intangible assets and
determined them to be appropriate. In the third quarter of the fiscal year ended
March 31, 2005, the Company recorded impairment loss on goodwill and intangible
assets of YEN 25,954 thousand.


Income Taxes
------------


The provision for income taxes is based on earnings before income taxes and
includes the effects of temporary differences between assets and liabilities
recognized for financial reporting purposes and income tax purposes and
operating loss carryforwards. Valuation allowances are provided against assets
that are not likely to be realized.


Foreign Currency Transactions
-----------------------------


Foreign currency assets and liabilities, which consist substantially of cash and
accounts payable for connectivity leases to international carriers denominated
in U.S. dollars, are stated at the amount as computed by using exchange rates at
the end of the quarter and the resulting transaction gain or loss is recognized
in earnings.


Derivative Financial Instruments
--------------------------------


In accordance with SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities," as amended by SFAS No. 138 and No. 149 (collectively, "SFAS
No. 133"), the Company recognizes all derivatives as either assets or
liabilities in the balance sheet and measures those instruments at fair value.
In accordance with SFAS No. 133, the Company designated interest swap contracts
as a hedge of the variability of cash flows to be paid related to interest on
floating rate borrowings (cash flow hedge) and an effective portion of the
derivative's gain or loss is initially reported as a component of other
comprehensive income and subsequently reclassified into earnings when the
underlying transaction affects earnings. An ineffective portion of the gain or
loss is reported in earnings immediately.


The Company enters into contracts to hedge interest rate risks and does not
enter into contracts or utilize derivatives for trading purposes.


Stock-Based Compensation
------------------------


The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" and related interpretations. Accordingly, the
companies recognize compensation expense in an amount equal to the excess of the
quoted market price over the exercise price of the option at the grant date. For
options with a vesting period, the compensation expense is charged to operations
ratably over the vesting period. The Company has not recognized any stock-based
compensation expense for the third quarter of the fiscal year ended March 31,
2005.


                                       21


Advertising
-----------


Advertising costs are expensed as incurred.



                                       22



Basic and Diluted Net Income per Share
--------------------------------------


Basic and diluted net income per share are computed using the weighted-average
number of shares of common stock outstanding during the third quarter of the
fiscal year ended March 31, 2005. IIJ's potential common shares, shares issuable
upon exercise of stock options or conversion of convertible notes, have been
excluded from the computation of diluted net income per share for the third
quarter of the fiscal year ended March 31, 2005 because the exercise price of
stock options is higher than the average market price of common stock and the
effect of conversion of convertible notes would be antidilutive. Diluted net
income per share does not include the effects of the following potential common
shares:



--------------------------------------------------------------------------------------------------------------------

                                                              At the end of the third quarter of the fiscal year
                                                                             ended March 31, 2005
                                                                           (As of December 31, 2004)
--------------------------------------------------------------------------------------------------------------------

                                                                                                       
  Shares issuable under stock options                                                                     545

  Shares  issuable  related  to  convertible  notes  on an
  "as-if-converted" basis                                                                                 558
--------------------------------------------------------------------------------------------------------------------


Other Comprehensive Income (Loss)

The Company entered into interest rate swap contracts to manage its interest
rate exposure resulting in a fixed interest rate for a portion of its long-term
debt.


On March 14, 2003, the Company  entered into a long-term  installment  loan
agreement  with a leasing  company to finance the  payment  for rental  deposits
given to other lessor for its new head office. The principal of the loan was YEN
345,433 thousand and YEN 456,265 thousand at the end of the third quarter of the
fiscal year ended March 31, 2005,  and at the end of the fiscal year ended March
31,  2004,  respectively,  and the loan is  secured by a first  priority  pledge
against a claim for the guarantee deposits of YEN 1,705,036 thousand.  Also, the
Company  provided  banks  with  collateral  for  outstanding  loans  by means of
establishing a second priority pledge against such guarantee deposits.


                                       28


The Company entered into bank overdraft agreements with certain Japanese banks
for which the unused balance outstanding at the end of the third quarter of the
fiscal year ended March 31, 2005, and at the end of the fiscal year ended March
31, 2004, was YEN 1,789,156 thousand and YEN 800,906 thousand, respectively.


The 1.750  percent  unsecured yen  convertible  notes due March 2005 in the
aggregate  principal amount of YEN 15,000,000  thousand were issued on April 11,
2000. The notes are  convertible  at the option of the holders  currently at YEN
19,875 thousand per share at any time on or before March 15, 2005. The notes are
currently  redeemable at the Company's option at any time before March 15, 2005,
in whole or in part, at par with unpaid and accrued interest;  provided that the
closing  trading  price for the Company's  shares for a certain  period prior to
giving notice of redemption is at least 140 percent of the conversion price. For
the fiscal year ended March 31, 2004, and third quarter of the fiscal year ended
March 31, 2005, the Company  repurchased  and cancelled a portion of convertible
notes.  At March 31, 2004, and at December 31, 2004, the Company had outstanding
convertible  notes  of YEN  11,832,000  thousand  and YEN  11,088,000  thousand,
respectively.


For the third quarter of the fiscal year ended March 31, 2005, IIJ concluded a
securities loan agreement with a financial institution and in exchange for
securities received cash of YEN 722,800 thousand, as of December 31, 2004. Such
transactions are accounted for as secured loans. Proceeds (amount received) from
the agreement are shown as payable under securities loan agreement. IIJ pays
interest on such loans at a variable rate 0.56% above LIBOR. The interest rate
was 0.6311% at December 31, 2004.


IIJ  provided  available-for-sale  securities  of YEN  989,600  thousand as
lending stock for the securities loan agreement.


6. Commitments and Contingent Liabilities


The Company adopted FASB Interpretation No. 45, "Guarantor's Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others" ("FIN 45"). FIN 45 elaborates on the disclosures to be
made by a guarantor about its obligations under certain guarantees. It also
clarifies that a guarantor is required to recognize, at the inception of a
guarantee, a liability for the fair value of the obligation undertaken in
issuing the guarantee.


In December 2001, a class action complaint alleging violations of the federal
securities laws was filed against the Company, naming IIJ, certain of its
officers and directors as defendants, and underwriters of IIJ's initial public
offering. An amended complaint was filed on April 24, 2002 alleging, among other
things, that the underwriters of IIJ's initial public offering violated the
securities laws (i) by failing to disclose in the offering's registration
statement certain alleged compensation arrangements entered into with the
underwriters' clients, such as undisclosed commissions or tie-in agreements to
purchase stock in the after-market, and (ii) by engaging in manipulative
practices to artificially inflate the price of IIJ's stock in the after-market
subsequent to the initial public offering. On July 15, 2002, the Company joined
in an `omnibus' motion to dismiss the amended complaint filed by the issuers and
individuals named in the various coordinated cases. In June 2003, the Company
approved a settlement with the plaintiffs in this matter. The settlement
releases IIJ and the individual defendants for liability for the conduct alleged
in the action. Under the settlement, the Company agreed to assign away, not
assert, or release certain potential claims the Company may have against IIJ's
underwriters. Approximately 260 defendant issuers participated in this
settlement. As to financial impact on the Company, the settlement provides that
the class members will be guaranteed $1 billion in recoveries by the insurers of
the issuers. In addition to IIJ's portion of the proposed settlement, some of
the continuing legal expenses incurred in connection with the partial settlement
would be borne by IIJ's insurer based on the settlement agreement and an
individual agreement between IIJ and IIJ's insurer. Consequently, the Company
believes that there will be no significant financial impact on the Company as a
result of this matter.


7. Derivative and Other Financial Instruments


Interest Rate Swap Agreement
----------------------------


The Company is exposed to changes in interest rates that are associated with
long-term bank borrowings. The Company's policy on managing the interest rate
risk is to hedge the exposure to variability in future cash flows of floating
rate interest payments on the long-term bank borrowings. In order to reduce cash
flow risk exposures on floating rate borrowings, the Company utilizes interest
rate swap agreements to convert a floating rate borrowing to a fixed rate
borrowing.


                                       29


The Company is also exposed to credit-related losses in the event of
non-performance by counterparties to interest rate swaps, but it is not expected
that any counterparties will fail to meet their obligations, because
counterparties are internationally recognized financial institutions.


Changes in fair value of interest rate swaps designated as hedging instruments
is reported in accumulated other comprehensive income during the third quarter
of the fiscal year ended March 31, 2005, and the fiscal year ended March 31,
2004.


Changes  in fair  value  of  interest  rate  swaps  designated  as  hedging
instruments are reported in accumulated  other  comprehensive  income during the
third quarter of the fiscal year ended March 31, 2005, and the fiscal year ended
March 31, 2004.  These  amounts  subsequently  are  reclassified  into  interest
expense  as a yield  adjustment  in the same  period  in which the  hedged  bank
borrowings  affect earnings.  The term,  notional amount,  and repricing date of
interest rate swaps exactly  match those of the long-term  borrowings.  The swap
terms are "at the market," so they have zero value at inception. Thus, there was
no  ineffectiveness  recognized  in earnings for the third quarter of the fiscal
year ended March 31, 2005,  and the year ended March 31,  2004.  At December 31,
2004,  the  notional  amount of  interest  rate swap  contracts  amounted to YEN
1,400,000  thousand,  and net  derivative  loss on those  contracts  totaled YEN
13,966 thousand.


8. Subsequent Events


(for the third quarter of the fiscal year ended March 31, 2005)


The Company repaid all of the outstanding  amount of the convertible  notes
due March 2005,  on the due date of March 31, 2005 with the  proceeds  from cash
and  cash  equivalent  and  gain  on  sale of a  portion  of  available-for-sale
securities  through  the fiscal year ended March 31,  2005.  Proceeds  and gross
realized  gain  from this sale were YEN  2,614,768  thousand  and YEN  2,477,607
thousand, respectively.
