Japanese Prime Minister Shinzo Abe will meet U.S. President Barack Obama on Wednesday ahead of this week's Group of Seven summit, a Japanese Foreign Ministry source said, with one topic being how to prevent crime by workers from U.S. military bases.
A U.S. civilian working on a base on Okinawa island was arrested last week in connection with the murder of a Japanese woman.
Okinawa, the site of a brutal World War Two battle, hosts the bulk of U.S. military forces in Japan and many residents resent what they see as an unfair burden.
Many also associate the bases with crime, pollution and noise. The rape of a Japanese schoolgirl by U.S. military personnel in 1995 sparked huge anti-base demonstrations.
Both governments want to keep the incident from fanning further opposition to an agreement to relocate the U.S. Marines' Futenma air base to a less populous part of Okinawa, a plan first agreed upon after the 1995 rape but opposed by the island's governor and many residents who want the base off the island entirely.
"The government is fully aware of the seriousness and graveness of the recent incident in Okinawa, and considering the feelings of the people, Prime Minister Abe will seek strict measures from President Obama," Japanese Chief Cabinet Secretary Yoshihide Suga said this week.
Suga said the leaders would also discuss the global economy, bilateral ties and other regional and global issues.
"We’d certainly expect Okinawa to come up," a U.S. official said separately, adding the meeting was still being finalized.
Obama is also set to make a historic visit to Hiroshima, site of the world's first atomic bombing, on Friday, after attending the G7 summit.
Both governments are hoping the Hiroshima visit will showcase the strong alliance between the former wartime foes.
Concerns about the health of the global economy will top the agenda at the G7 summit, although full agreement on macro-economic policy looks hard to come by.
"I want to make this a summit at which the G7 sends a clear, strong message to respond to all situations and contribute to the sustainable, strong growth of the world economy," Abe told reporters.
Summit topics also include terrorism, refugees, trade, cyber security and maritime security, including China's assertiveness in the East and South China Seas, where Beijing has territorial disputes with Japan and several Southeast Asian nations.
The G7 groups Britain, Canada, France, Germany, Italy, Japan and the United States. The Japanese Foreign Ministry source also said Abe would meet British Prime Minister David Cameron on Wednesday.
