HITACHI COMMUNICATION TECHNOLOGIES, LTD. AND HITACHI, LTD. COMPLETE ASSET ACQUISITION OF U.S.'S SALIRA OPTICAL NETWORK SYSTEMS TO STRENGTHEN DEVELOPMENT OF OPTICAL ACCESS SYSTEMS BUSINESS

TOKYO, Japan – April 25, 2005 – Hitachi Communication Technologies, Ltd. (President: Eiji Aoki) and Hitachi, Ltd. (NYSE:HIT/TSE:6501) today announced the April 1, 2005 closing of their joint acquisition of substantially all of the assets of U.S.-headquartered Salira Optical Network Systems, Inc., a leading developer and manufacturer of GE-PONs, in a move designed to strengthen the respective optical access systems businesses of Hitachi Communication Technologies and Hitachi.

Hitachi Communication Technologies and Hitachi have jointly established a subsidiary to hold the assets acquired from Salira Optical Network Systems, Inc. and will operate the new business under the name "Salira Systems, Inc.". Hitachi Communication Technologies and Hitachi expect to position Salira Systems, Inc. as one of the development bases for their global expansion of the optical access systems business. This acquisition is expected to strengthen Hitachi Communication Technologies' GE-PON development capabilities, and give impetus to the full-scale development of business in the global optical access markets where high growth is expected.

GE-PON (Gigabit Ethernet Passive Optical Network) is a system in which an optical splitter is used in an optical access network to branch out signals from a single optical fiber, thereby facilitating Gigabit Ethernet in the multiple homes of subscribers.

Salira Optical Network Systems was established in July 2000 and developed advanced optical access GE-PON products and carried out various laboratory trials and field tests jointly with major telecommunication carriers.

Hitachi Communication Technologies has positioned optical access systems as one of its core businesses since its establishment in October 2002. Hitachi Communication Technologies expects to benefit from the acquired optical access business know-how as well as the acquired business' ability to develop system products suited to needs in the global markets. It is expected that this will help improve the efficiency of GE-PON product development at Hitachi Communication Technologies.

Hitachi Communication Technologies and Hitachi expect the world optical access systems market to enter a full-scale expansion phase in 2006. To become world-leading suppliers in the optical access systems business, the two companies plan to drive the global development of business with GE-PON and other optical access products.
