U.S. Marine Arrested in Killing of Okinawa Woman, Japan Calls It 'Heinous'
The killing of a woman in Okinawa, allegedly by a young U.S. Marine, has sparked outrage across Japan, with the country's prime minister calling it a "heinous" crime and officials demanding that the U.S. military tighten discipline.
Japanese police arrested Lance Cpl. Devin Jacob Ballard, 20, on Sunday, October 4, on suspicion of murder and robbery. He has denied involvement, according to police.
What Police Say Happened
The victim, 39-year-old Anna Yagi, was found dead at a hotel in Naha, Okinawa's capital, at about 4:30 a.m. on Saturday, October 3, according to ABC News. Police believe she was killed sometime between 2 and 4 a.m. Investigators said she died of suffocation caused by pressure on her neck.
Security camera footage showed a person who appeared to be a foreigner entering the hotel with a woman and later leaving with her belongings, police said. Investigators said the person's hair and tattoos resembled Ballard's. Some of the victim's belongings were later found abandoned near the hotel.
Ballard was located late Saturday night in an entertainment district in Okinawa City and arrested the following day.
He is assigned to the III Marine Expeditionary Force at Marine Corps Air Station Futenma, which sits in the middle of the city of Ginowan near Naha.
Japan's Leaders Respond
Prime Minister Sanae Takaichi condemned the killing.
"The occurrence of such an extremely brutal and heinous incident is a matter of profound regret," she said. She said the Japanese government had lodged a strong protest with the United States and urged the U.S. side to cooperate fully and enforce military discipline.
Japan's foreign and defense ministers summoned senior U.S. officials to formally protest. Foreign Minister Toshimitsu Motegi "strongly urged the U.S. side to strengthen discipline" to prevent future incidents, his office said.
Okinawa Gov. Genta Koja said the crime was "extremely malicious in nature" and had "hugely shocked residents."
"I am infuriated," Koja said, according to CBS News. He also criticized U.S. efforts to educate service members about behavior and discipline as ineffective.
The U.S. Response
U.S. Ambassador to Japan George Glass said his office was "providing full cooperation" with Japanese investigators.
The III Marine Expeditionary Force said in a statement, "We extend our deepest condolences to the victim's family and friends."
Protests and a Long History of Tension
About 100 people rallied in Naha to protest the killing, and another demonstration was organized in Tokyo.
The case has reopened deep frustration in Okinawa, which hosts about 70% of U.S. military facilities in Japan despite making up a tiny share of the country's land. Crimes involving American service members have long fueled resentment on the island.
In 2025, a U.S. Marine was sentenced to seven years in prison for attempted rape in Okinawa. In 2017, a former Marine who worked as a civilian on a U.S. base was sentenced to life in prison for the rape and murder of a 20-year-old Okinawan woman, a case that drew tens of thousands of protesters.
Many Okinawans have pushed for years to reduce the U.S. military presence and to relocate Futenma, which is surrounded by homes and schools. The American military footprint overseas has been shifting in other parts of the world, including the recent U.S. withdrawal from Iraq, but Japan remains one of its most important bases in Asia.
Under the agreement that governs U.S. forces in Japan, American service members accused of crimes can sometimes be held by the U.S. military until they are charged. In this case, Ballard was arrested and is in the custody of Japanese police.
