US Marine Arrest in Okinawa Sparks Renewed Protests Over American Military Crimes
On October 3, Okinawa police arrested 20‑year‑old Lance Corporal Devin Jacob Ballard of the U.S. Marine Corps on accusations of robbing and murdering a 39‑year‑old hotel guest in Naha. The incident has reignited a decades‑old frustration among Okinawan residents who accuse the American military of a pattern of violent and unlawful behaviour.
"Not again," said 52‑year‑old resident Ai Sato, echoing a sentiment that many local voices share. "We have had enough of these victims and the families who suffer," she told the BBC. Similarly, Ginowan native Akemi Oshiro said the series of incidents had eroded any surprise for locals, leading to a sense that the same crimes have simply become routine.
Ballard was stationed at Marine Corps Air Station Futenma and appointed to the III Marine Expeditionary Force. Japanese police say the alleged crime was unrelated to his official duties, meaning that Japan has primary jurisdiction. When a suspect under U.S. custody is subject to Japanese jurisdiction, Japan can hold the suspect until it brings charges. The U.S. has 55,000 troops in Japan, 70 % of whom are based in Okinawa, the smallest Japanese prefecture by area, but with the highest military concentration.
The murder victim, Anna Yagi, died early on October 3 in a hotel room in Naha. Security footage suggests Ballard entered the hotel with Yagi and left alone with her belongings; she had been strangled with a cord, investigators report. Tokyo’s Prime Minister Sanae Takaichi has recorded an official protest with Washington, but many residents feel that still falls short of demanding concrete changes.
The arrest has sparked protests in Naha and Tokyo, with about 100 people gathering in each city. Social media posts have flooded with angry remarks, one user writing, "Enough is enough." Residents urge the Japanese and U.S. governments to take tangible steps to prevent future incidents.
Okinawa’s history of conflict with the U.S. military dates back to the island’s return to Japanese control in 1972. Since then, more than 6,400 arrests of U.S. service members have been recorded for criminal offences. The 2016 rape and murder of a 20‑year‑old local woman sparked mass demonstrations, and in 2025 a U.S. Marine was convicted of choking and sexually assaulting a Japanese woman.
Citizens describe a pervasive sense of unease: 48‑year‑old mother Hitomi Miyagi said, "Even 80 years after the war, Okinawa is still an unnerving place." She adds, "We will not stop raising our voices for a peaceful Okinawa."
