The wives of the leaders of the Group of Eight nations will visit a peace memorial in Okinawa while in the prefecture for the G8 summit slated for July 21-23, government sources said Tuesday.

The wives will visit Heiwa no Ishiji (Cornerstone of Peace) memorial, which bears the names of victims of the Battle of Okinawa during World War II, the sources said.

Tokyo arranged the visit after Okinawa Gov. Keiichi Inamine filed petitions with the embassies of each country asking their leaders to visit U.S. bases in Okinawa and the memorial during the summit.
