Japan protests to US after Marine arrested for murder in Okinawa

Japan’s foreign ministry lodged a formal grievance on Sunday after a U.S. Marine was arrested in connection with the death of a local woman in the island’s capital, Naha. The protest, described by foreign minister Toshimitsu Motegi as “strong,” was submitted to Washington amid renewed sensitivities surrounding the U.S. military presence on Okinawa.

The suspect, 20‑year‑old lance corporal Devin J. Ballard of the Third Marine Expeditionary Force, is being held by Japanese authorities in Naha. Police say Ballard is accused of robbing and killing 39‑year‑old Anna Yagi, whose body was discovered at a hotel in the city. Surveillance footage released by local police reportedly shows Ballard entering the hotel with Yagi early on Saturday, after which she was found dead.

Ballard has denied the allegations, and U.S. officials have indicated that the Marine is cooperating with the investigation. The U.S. embassy in Tokyo issued a statement expressing “sincere condolences to the victim’s family” and confirming that Washington is working closely with Japanese law‑enforcement agencies on the case.

The incident arrives at a time of ongoing local opposition to the concentration of U.S. bases on Okinawa, where roughly 30,000 active‑duty American service members are stationed. The island has long been a focal point for peace and anti‑base movements, and the Japanese government’s protest underscores concerns that high‑profile crimes involving U.S. personnel could inflame public sentiment.

Both governments have emphasized the importance of continued cooperation in the investigation, while Japanese officials have warned that the case could revive broader debates over the U.S. military footprint on the island.
