    TOKYO--(BUSINESS WIRE)--March 29, 2007--Internet Initiative Japan
Inc. ("IIJ", NASDAQ: IIJI, TSE1: 3774), one of Japan's leading
Internet access and comprehensive network solutions providers, today
announced that its Board of Directors resolved to acquire 100% of the
equity of hi-ho, Inc. ("hi-ho") from Panasonic Network Services Inc.
("PNS"). hi-ho will become a consolidated subsidiary of IIJ on June 1,

becoming more common in Japan, Internet users are facing more threats
such as cyber-attacks, computer viruses, spam and phishing. As a
result, demand for a safer Internet environment is continually
increasing. Through this acquisition, IIJ plans to expand its Internet
service business by enhancing the development and provision of
high-quality network-related services that consumers can use more
safely, leveraging its engineering and network operating expertise
that it has cultivated in its Internet related business for its
corporate customers.

IIJ and Panasonic Network Services Reach Agreement on Transfer of ISP Operations

Internet Initiative Japan Inc. ("IIJ") and Panasonic Network Services Inc.
("PNS"), which is a 100% owned subsidiary of Matsushita Electric Industrial
Co., Ltd., today announced that both companies agreed to transfer PNS's
Internet Service Provider ("ISP") business, currently operating under the
"hi-ho" service brand, and the corporate solutions business based on this
service, to IIJ.

As part of the agreement, PNS will spin off these ISP-related operations into a
wholly-owned subsidiary under the name hi-ho, Inc., on June 1, 2007. On that
date, IIJ will acquire the new company through a transfer of all its shares from
PNS to IIJ. The "hi-ho" service brand and associated domain name will remain
unchanged and service will continue uninterrupted.

Since 2001, low-cost ADSL and FTTH (Fiber-to-the-home) broadband services has
been continually growing among Internet users, and the equipment connected to
the broadband network has also diversified from the conventional PCs and mobile
phones to digital televisions and other information appliances. At the same
time, the Internet contents have transformed as well. Under these changes, new
threats on the Internet security, such as phishing, are emerging and expanding.

IIJ pioneered high-quality, reliable Internet services primarily to corporate
customers in Japan, and will use its long experience and technical strengths to
provide individual customers with the same safe and secure network services and
products. As part of the Matsushita Electric Group, whose strengths lay in
digital television and mobile phone manufacturing, PNS is shifting its focus to
network services for household appliances. Thus both companies consider this
asset transfer mutually beneficial.

IIJ and PNS will continue to build their relationship by leveraging each other's
strength and cooperating on new network services.
