October 7: A 20-year-old United States Marine is in Japanese custody on suspicion of killing a 39-year-old woman in a hotel in Naha, the capital of Okinawa, and taking her belongings. Japanese prosecutors began examining the case on Tuesday to decide on formal charges, the Associated Press (AP) reported. The Marine denies the allegations, according to CBS News and Stars and Stripes. The case has drawn a formal protest from Tokyo, a demand from Okinawa’s governor to revise the agreement that governs US forces in Japan, and a street protest in Naha.
Key highlights
- The Marine Corps identified the suspect as Lance Corporal Devin Jacob Ballard, 20, of III Marine Expeditionary Force, ABC News reported. The victim was Anna Yagi, 39, of Naha.
- Police allege he killed her in a Naha hotel early on Saturday, October 3, and took her wallet and backpack. He denies it.
- Prime Minister Sanae Takaichi called the crime “extremely brutal and heinous” and said Japan had lodged a strong protest, Military Times reported.
- Okinawa Governor Genta Koja told the top Marine commander on the island that US discipline and education efforts were “completely ineffective”, Stars and Stripes reported.
- About 160 people protested in Naha on Monday, according to AP.
What police allege
Police say the killing took place between 2 a.m. and 4 a.m. on Saturday in a hotel in Naha, according to a police statement carried by NHK and cited by Military Times. ABC News reported that the body was found at about 4:30 a.m. Police allege that Ballard pressed on Yagi’s neck and caused her death by asphyxiation, Stars and Stripes reported, and that he took her wallet and backpack, according to AP. ABC News reported that the backpack was later recovered near a hotel with the wallet still inside.
Security camera footage showed a man matching the suspect’s appearance entering the hotel with the woman and leaving alone, AP reported. He was arrested after a patrolling officer noticed him in an entertainment district in Okinawa City, about 25 kilometres north-east of Naha, and matched his shaved head and arm tattoos to the footage, according to AP and CBS News.
Ballard has denied the allegations, CBS News and Stars and Stripes reported. Under Japanese law a suspect is presumed innocent until a court rules otherwise. Police sent the case to prosecutors on Monday, Stars and Stripes reported. AP said a conviction for robbery and murder could bring life imprisonment or the death penalty.
The reports differ on one detail. AP, CBS News and Stars and Stripes say Ballard is assigned to Marine Corps Air Station Futenma. Military Times placed him with III Marine Expeditionary Force at Camp Courtney, where that force has its headquarters.
Tokyo’s protest
Takaichi wrote on social media that the incident was “extremely brutal and heinous” and that Japan had lodged a strong protest and asked for cooperation with the investigation and steps to prevent a repeat, Military Times reported. AP quoted her as saying that “the occurrence of the heinous crime is extremely regrettable”.
Defence Minister Shinjiro Koizumi summoned Lieutenant General Stephen Jost, the commander of US Forces Japan, and Foreign Minister Toshimitsu Motegi conveyed his outrage to US Ambassador George Glass, AP reported. “Incidents and accidents involving U.S. military personnel cause significant anxiety to the local community and must never occur,” Koizumi wrote, as quoted by Military Times.
Glass offered condolences and pledged “full cooperation as the investigation continues”, CBS News reported. III Marine Expeditionary Force said the Marine Corps “takes these allegations very seriously and expects every Marine to adhere to the highest standards of behavior”, according to Military Times, and that it was cooperating with the Japanese authorities, ABC News reported.
Okinawa’s response
Governor Genta Koja and Naha Mayor Satoru Chinen met Lieutenant General Benjamin Watson, who commands III Marine Expeditionary Force, and US Consul General Andrew Ou to protest, Stars and Stripes reported. “The fact that such an atrocious crime has again taken place leads us to conclude that U.S. military efforts regarding discipline and human rights education are completely ineffective,” Koja said, according to the newspaper. He asked for a revision of the US-Japan Status of Forces Agreement, stricter discipline and preventive measures.
“It is absolutely unforgivable and we are outraged,” Koja said, as quoted by AP. Watson replied: “Any serious incidents that cause anxiety and concerns for the people of Okinawa cause us concern. We are committed to being good neighbors,” Stars and Stripes reported.
The victim’s brother said in a statement carried by CBS News: “We have lost a family member and are deeply saddened. My parents, in particular, are utterly devastated.” About 160 people gathered in Naha on Monday, and one sign read “We’ve had enough of this!”, AP reported.

Background: a long list of cases
AP puts the number of US troops in Japan at about 50,000, with roughly half of them on Okinawa. Criminal cases linked to the US military rose to 101 last year from about 40 in 2020, the agency reported.
The best-known case is the 1995 rape of a 12-year-old girl by three US service members, which set off mass protests, Military Times recalled. Stars and Stripes listed two earlier killings: one in 2016 by a former Marine, after which troops were placed under a midnight curfew and an alcohol ban, and one in 2019 by a Navy petty officer. Since October 2024, US personnel on Okinawa have been barred from drinking off base between 1 a.m. and 5 a.m., the newspaper said. ABC News reported that no change to those liberty rules had been announced.
What it means for Japan and the region
The case lands on two fault lines at once. The first is inside Japan. Okinawa carries a large share of the US military presence, and each serious crime renews the argument that the island bears a burden the rest of the country does not. Koja’s call to revise the Status of Forces Agreement goes further than Tokyo’s request for discipline and prevention, and the gap between those two positions is where the political pressure will build.
The second is the alliance itself. The US bases on Okinawa sit close to Taiwan and the East China Sea, and both governments describe them as central to deterrence in the region. Takaichi, who in her recent Diet speech called China an “important neighbour”, now has to show Okinawans that a protest produces results without unsettling the alliance. For other Asian countries that host US forces, how Washington answers Tokyo will be watched closely.
What to watch
- Whether prosecutors indict Ballard, and on what charges.
- Whether the US military tightens its liberty rules on Okinawa, as it did after the 2016 killing.
- Whether Tokyo takes up the governor’s demand for changes to the Status of Forces Agreement or limits itself to preventive measures.
- The size of further protests in Okinawa.
