The alleged murder of a Japanese woman by a US Marine in Okinawa has triggered widespread public anger in Japan, renewing scrutiny of the long-standing security alliance and the history of criminal incidents involving American personnel.
Prime Minister Sanae Takaichi condemned the incident on Monday as a “heinous crime,” stating that the Japanese government had lodged a strong protest with Washington. She urged for full cooperation with the investigation and strict discipline among US military staff.
The disturbance began on Sunday when approximately 100 people gathered in Naha, the capital of Okinawa, to protest after news emerged that a US Marine had allegedly killed a 39-year-old woman at a hotel the previous day and stolen her wallet. According to public broadcaster NHK, security footage captured a foreign man entering a room with a woman and leaving alone with her belongings. Police subsequently arrested a 20-year-old man matching the description.
Authorities have identified the suspect as Devin Jacob Ballard and the victim as Anna Yagi. Reports indicate that Ballard has denied the allegations.
Kozue Akibayashi, a professor of gender and peace studies at Doshisha University in Kyoto, argued that the tragedy underscores a persistent structural issue. “The Japanese government has always chosen the US-Japan alliance over the safety and lives, and voices of the people of Okinawa,” she told Al Jazeera.
Japan currently hosts roughly 54,000 US military personnel. However, Okinawa bears a disproportionate share of this presence, accommodating approximately 70 percent of US military facilities in the country. These arrangements stem from a bilateral security treaty and the Status of Forces Agreement (SOFA), initially signed in 1951 and revised in 1960.
Under the SOFA, Japan holds primary jurisdiction over crimes committed by US personnel off-base while they are not on duty, whereas the US retains primary jurisdiction for offenses occurring on bases or during duty hours.
Tokyo and Washington view Okinawa as a strategic bulwark against potential military aggression from China. Akibayashi noted that both governments frequently cite the archipelago’s geopolitical significance to justify the heavy military concentration. “However, in reality, it was convenient for the Japanese government to keep the larger number of US troops and military facilities in Okinawa that nobody wants,” she explained.
Okinawa constitutes just one percent of Japan’s population and less than one percent of its territory. Akibayashi added that the islanders’ political influence appears minimal in Tokyo, compounded by historical discrimination dating back to Japan’s annexation of the Ryukyu Kingdom in 1879.
After the US administered Okinawa from the end of World War II until 1972, it transferred many bases from the main Japanese islands to Okinawa to alleviate local protests on the mainland. Since then, resentment has frequently flared over noise pollution, aircraft crashes, and misconduct by service members.
The current case follows a troubling pattern of alleged crimes. In 2024, a Japanese court sentenced a US Marine to seven years in prison for choking and attempting to rape a woman in her twenties. In 2017, a former Marine and civilian base worker received a life sentence for the rape and murder of an Okinawan woman, while another Marine was implicated in a fatal drunk-driving crash that killed a 61-year-old local driver.
The most notorious incident occurred in 1995, when the rape of a 12-year-old girl by three US servicemen sparked mass protests. According to the Yomiuri Shimbun, roughly 6,000 US military personnel have been arrested since 1972, with 80 arrests recorded in 2024, marking the highest figure in two decades.
Japanese officials have expressed continued alarm. Defence Minister Shinjiro Koizumi stated that incidents involving US military personnel cause significant anxiety within local communities and must be prevented.
The US Embassy and the Marine Corps issued condolences and pledged full collaboration. A Marine Corps spokesperson confirmed that Ballard, assigned to the III Marine Expeditionary Force based at Marine Corps Air Station Futenma, is in Japanese custody. “The Marine Corps takes these allegations very seriously and expects every Marine to adhere to the highest standards of behavior,” the statement read.
US Ambassador George Glass also offered sincere condolences and promised continued cooperation with investigators.
Despite such promises, Akibayashi remained skeptical about meaningful change. She observed that whenever crimes are committed, “the US government and the military always say they would address the issue or promise tighter discipline,” adding, “They never worked.”
Okinawa bears too much of the burden. It is frustrating to see their safety consistently ignored for political strategy.
This keeps happening and nothing changes. The SOFA needs a serious overhaul before another life is lost.
