Prime Minister Yukio Hatoyama is planning to go back to Okinawa Prefecture around May 23 and formally propose his plan for the relocation of U.S. Marine Corps Air Station Futenma to Gov. Hirokazu Nakaima, government sources said Tuesday.

At a news conference, Chief Cabinet Secretary Hirofumi Hirano gave no exact date for Hatoyama's planned visit but acknowledged the prime minister's intention to visit Okinawa sometime in May.

"I believe it is the prime minister's intention to hopefully visit" Okinawa by the end of the month, Hirano said.
