US Marine arrested for murder prompts month‑long curfew on Okinawa troops
Lance Corporal Devin Jacob Ballard, 20, of the U.S. Marine Corps’ Futenma Air Station, was arrested on Sunday on suspicion of robbing and murdering 39‑year‑old Anna Yagi at a hotel in Naha, Okinawa.
The arrest prompted III Marine Expeditionary Force commander Lt. Gen. Benjamin Watson to order a 48‑hour pause in operations and to impose a month‑long curfew on all U.S. service members stationed on the island, citing the need for “reflection” on discipline, standards and alliance responsibilities.
Police say Yagi died from suffocation caused by pressure on her neck, according to Japanese broadcaster NHK. Ballard denies the allegations, and it was not immediately clear whether he has legal representation.
Prime Minister Sanae Takaichi called the incident “brutal and heinous” in an Oct. 4 post and announced a strong protest to the United States, urging full cooperation with the investigation, stricter discipline among U.S. personnel, and measures to prevent a recurrence.
She will meet Okinawa Governor Genta Koja on Wednesday to discuss the response, amid protests in Naha and Tokyo that echo decades of local opposition to the U.S. military footprint.
About 18,000 Marines are stationed on Okinawa, part of a U.S. presence of roughly 80,000 people on the island. Crime involving U.S. service members has risen sharply, from about 40 cases in 2020 to 101 in 2025, according to Okinawa prefectural police.
Historical incidents—including the 1995 kidnapping and rape of a 12‑year‑old girl, the 2017 murder of Rina Shimabukuro by a former Marine, and the 2024 conviction of an Air Force airman for assaulting a minor—have fueled ongoing protests and calls for relocation of forces.
Watson said the curfew and subsequent training period, which will include discussions on liberty policy, alcohol awareness and cultural responsibilities, are intended to remind troops that “liberty is a privilege and a collective responsibility.”
The next steps include continued investigation by Japanese authorities, further coordination between Washington and Tokyo, and monitoring of the curfew’s impact on the island’s security environment.
