The focus of America's business interests in Japan has changed from "trading with Japan" to "doing business in Japan," according to a biennial report released Wednesday by the American Chamber of Commerce in Japan.

The ACCJ meanwhile urged Tokyo to further liberalize Japanese markets, especially in telecommunications. The report specifically calls for more competition among the group companies of Nippon Telegraph and Telephone Corp., the country's dominant telecom carrier.

Reflecting changing U.S. corporate interests here, the latest report bears the title "2001 U.S.-Japan Business White Paper," instead of "U.S.-Japan Trade White Paper," which has been used since the 1970s, ACCJ President Robert Grondine said at a news conference.
