1. It is stipulated in “the Basic Law on the Formation of an Advanced Information and Telecommunications Network Society” that enrichment of content shall be promoted through close linkage with expansion of advanced information and telecommunication networks.

2. The IT Strategy Headquarters of Japan set the goal in the e-Japan strategy that within five years, at least 40 million household will enjoy continuous connection (ultra) high-speed Internet services. To achieve the goal effectively based on market principles, killer content is indispensable in demand boosting.

What is What is HSACHSAC ? ?

HIKARI Service Architecture Consortium (HSAC)HIKARI Service Architecture Consortium (HSAC) aims to make “HIKARI Service PlatformHIKARI Service Platform” a reality.

- The Platform provides consistent interfaces for both senders and receivers.- The Consortium studies functional models of HIKARI services and

requirements for the Platform.

- Study reports of HSAC are completely open to everyone. http://www.hikari-sac.org/e/index-e.html

- Market creation of HIKARI services is in progress in collaborated HSAC-based companies.
