A 20‑year‑old US Marine, Devin Jacob Ballard, stationed at Futenma Air Station, was indicted for strangling and robbing Anna Yagi, a 39‑year‑old Japanese hotel guest, in Naha, Okinawa. Video evidence and statements from investigators support the charges, though Ballard denies the allegations.

The case is the latest in a series of military‑related crimes that have strained US‑Japan relations, especially in Okinawa, home to the largest concentration of US troops abroad.
US Marine Indicted in Murder of Japanese Woman Sparks Protests
A 20‑year‑old US Marine, Devin Jacob Ballard, was indicted on suspicion of strangling and robbing Anna Yagi, a 39‑year‑old Japanese woman, at a hotel in Naha, Okinawa, on 3 October.
Ballard, stationed at US Marine Corps Air Station Futenma, is alleged to have used a telephone cord to strangle Yagi and then stole her backpack and wallet. Security footage shows a man believed to be the suspect entering the hotel with Yagi and leaving alone with her belongings.
While Ballard denies the allegations, investigators say he has made statements that suggest involvement. Prosecutors are pursuing charges of murder, robbery, and sexual exploitation.
The death of Yagi has provoked outrage across Japan. Prime Minister Sanae Takaichi called the crime “brutal and heinous” and the government registered a strong protest with the United States, demanding strict disciplinary action against US military personnel.
Okinawa governor Genta Koja condemned the incident as a sign of a lack of discipline and reiterated calls for the US to prevent such crimes. The incident follows a history of US military‑related crimes in the region, including four sexual‑assault cases in 2024 and a 2025 sentencing of a Marine for rape.
Around 100 people protested in both Naha and Tokyo, and social media users demanded justice, with comments calling for “enough is enough.” The case highlights ongoing tensions over the presence of approximately 55,000 US troops in Okinawa, the most heavily‑concentrated US military installation in Japan.
