Foreign Minister Yoriko Kawaguchi vowed Sunday to try to meet a call by Okinawa's governor for "tangible improvements" in reducing the heavy U.S. military presence in Okinawa Prefecture.

Kawaguchi reiterated the central government's commitments in a meeting with Keiichi Inamine, the island prefecture's governor.

The meeting covered other issues, such as Okinawa's demand to set a 15-year limit on the U.S. military's use of a planned airport as well as changes to the bilateral agreement on the status of U.S. military personnel.
