Toshimitsu Motegi, the new minister in charge of Okinawa and affairs related to the Northern Territories, says he will review what Japan can do to improve implementation of the accord that governs U.S. military activities in the country.

"The people of Okinawa Prefecture may wonder what the government means when it says it will 'improve the implementation' of the agreement," said Motegi in a recent interview.

"I intend to consider seriously what and how much improvement (Japan) can make to wipe out Okinawa's concerns," said the 48-year-old Lower House member of the Liberal Democratic Party, who served as senior vice foreign minister until he was appointed to his new ministerial post last week.
