A 20‑year‑old US Marine, Lance Corporal Devin Jacob Ballard, was taken into custody by Japanese police on Sunday after police linked him to the murder of Anna Yagi, a 39‑year‑old hotel guest in Naha, Okinawa.
“Not again,” 52‑year‑old resident Ai Sato told the BBC, echoing a collective grief that has simmered for decades. “We will stop becoming surprised at the same terrible incidents.”
Sato’s frustration reflects a historical pattern of crimes committed by US service members on the island, including robberies, rapes and assaults, many of which have led to protests that have drawn thousands of Okinawan residents.
Ballard, assigned to the III Marine Expeditionary Force and stationed at Marine Corps Air Station Futenma in Ginowan City, is not on official duty when it is thought he committed the crime, a fact that places the primary criminal jurisdiction with Japan. Under the Status of Forces Agreement, however, US authorities can retain custody until Japanese prosecutors file charges, a practice that has often left victims and their families feeling abandoned.
Video footage displayed by police reportedly shows Ballard entering the hotel with Yagi, leaving alone with her belongings, and an alleged strangulation by cord. Police confirmed that Yagi was found dead early on 3 October in a hotel room in Naha.
Prime Minister Sanae Takaichi registered an official protest with Washington, but local activists view her statement as a thin gesture. “I want her to call the President of the United States directly and demand concrete steps to stop these crimes, again,” Sato urged.
In the days since the arrest, roughly 100 people marched in Naha and another group gathered in Tokyo to voice their anger. Social media buzzed with posts calling for justice and the end of the current system that has, critics say, protected US servicemen from accountability.
Okinawa’s unique situation stems from being home to about 70% of Japan’s US military land use and hosting some 55,000 American troops. Since the islands were returned to Japan in 1972, there have been 6,409 arrests of US personnel for offenses committed on Okinawa, according to the Prefectural Government.
Past incidents compound the present outrage: the 2016 rape and murder of a young woman sparked 70,000‑strong protests; in 1995 the abduction and assault of a 12‑year‑old girl led to the first U.S. Marine life sentence in Okinawa; and in 2025 a Marine was convicted of choking and sexually assaulting a Japanese woman.
Local voices keep warning that the heavy American military presence “has an unnerving effect even eight decades after the war” and that the island’s future requires a shift toward peace and equal rights for all residents.
