Foreign Minister Makiko Tanaka will pay a weekend visit to Honolulu on her way back from San Francisco to encourage the salvage crew attempting to move the Ehime Maru, the Japanese fisheries training vessel sunk by a U.S. submarine in February, according to ministry officials.

Tanaka is scheduled to leave Japan for San Francisco on Friday to attend Saturday's commemoration of the 50th anniversary of the signing of the San Francisco Peace Treaty, which officially ended World War II. The event is being sponsored by a private group.

Also on Saturday, Tanaka and U.S. Secretary of State Colin Powell will host a separate ceremony commemorating the 50th anniversary of the Japan-U.S. Security Treaty, which was signed several hours after the peace treaty, the officials said.
