Japanese Prime Minister Yukio Hatoyama has sacked Social Democratic Party leader Mizuho Fukushima as the consumer affairs minister from his cabinet. State broadcaster NHK today reported the dismissal came after Fukushima refused to sign the cabinet resolution on the issue concerning the relocation of the U.S. Futenma base. On Thursday, Japan and the United States have agreed to relocate the Futenma airbase in Okinawa.
