TOKYO (AP) - The southern Japan island of Okinawa has marked the 68th anniversary of a decisive and bloody World War II battle that hastened Japan's surrender but left the island with a heavy US military presence that is still the source of intense friction and frequent protests.
Sunday's ceremony was attended by Prime Minister Shinzo Abe and other Japanese officials, along with US Ambassador John Roos, who is the first US ambassador to attend the ceremony in 18 years.
More than 200,000 people are believed to have died in the 1945 battle for Okinawa.
Roughly 50,000 US troops are stationed in Japan under a mutual security pact. About half, including thousands of US Marines and a major Air Force Base, are located on Okinawa.
Protests against the US troops are common on Okinawa amid concerns over crowding, troop-related crimes and the danger of accidents.
