Japanese Prosecutors Charge U.S. Marine in Okinawa Killing
Japanese prosecutors have formally charged U.S. Marine Devin Jacob Ballard with murder and robbery in the death of Anna Yagi, the Guardian reported. Yagi, 39, was found dead in Naha, the capital of the Japanese island prefecture of Okinawa.
Ballard is a 20-year-old lance corporal, a junior enlisted rank in the U.S. Marine Corps. He is assigned to Marine Corps Air Station Futenma, a U.S. military base in Okinawa. According to the charges, he fatally strangled Yagi at a hotel and stole her backpack, which contained a wallet. Prosecutors indicted him on Sunday, according to the same report.
Ballard has reportedly denied the murder and robbery charges. Surveillance camera footage showed a man entering a room with a woman and later leaving with her belongings, according to the Guardian.
Yagi was found dead about a day before Ballard was arrested on 4 October. Reuters reported that Japanese leader Takaichi protested to the United States after the Marine was accused of murder. AP reported that Japan's leaders condemned the killing.
The case prompted protests in Okinawa and in Tokyo. It also led to a curfew and an alcohol ban for U.S. military members stationed in Okinawa, measures that restrict when personnel may be out and what they may drink.
Okinawa hosts most of the 54,000 U.S. troops stationed in Japan, and crimes involving American service members have long been a sensitive issue there. Yomiuri Shimbun reported that about 6,000 U.S. military personnel have been arrested since the United States returned Okinawa to Japanese control in 1972. The Guardian reported that there were 80 arrests of U.S. military personnel in 2024, a 20-year high.
Earlier cases have ended in lengthy prison terms. In June 2025, a Japanese court sentenced U.S. Marine Jamel Clayton, then 22, to seven years for choking and sexually assaulting a woman in her 20s. In 2017, former U.S. Marine Kenneth Shinzato was sentenced to life in prison for the rape and murder of an Okinawa woman.
