Outrage in Japan as US Marine Allegedly Murders Woman in Okinawa, Reigniting History of Military Crime

People in Tokyo protested against the killing of a woman in Okinawa allegedly committed by a US Marine Corps member, on October 5, 2026. The murder of a Japanese woman allegedly committed by a US marine on the southern island of Okinawa has sparked public outrage across Japan, highlighting a long history of incidents involving American personnel.

Japan’s Prime Minister Sanae Takaichi condemned the incident as a “heinous crime” on Monday, announcing that the government had lodged a strong protest with Washington while demanding “full cooperation with the investigation” and “strict discipline among US military personnel”.

Approximately 100 individuals gathered for a rally in Naha, the capital of Okinawa, on Sunday following reports that a US marine had allegedly killed a 39-year-old woman at a local hotel and stolen her wallet just a day prior. Public broadcaster NHK reported that security camera footage captured a foreign man entering a room with a woman and later departing alone with her belongings. Police subsequently apprehended a 20-year-old man matching that description, though the suspect has reportedly denied the allegations.

Authorities identified the suspect as Devin Jacob Ballard and the victim as Anna Yagi. Kozue Akibayashi, a professor of gender and peace studies at Doshisha University in Kyoto, Japan, stated that the event highlights decades of systemic issues.

“The Japanese government has always chosen the US-Japan alliance over the safety and lives, and voices of the people of Okinawa,” she informed Al Jazeera.

The United States currently stations roughly 54,000 military personnel in Japan. Okinawa shoulders an unequal burden, accommodating about 70 percent of all US military facilities in the nation under a bilateral security treaty and Status of Forces Agreement (SOFA) established initially in 1951 and revised in 1960.

Under these agreements, Japan holds the “primary right to exercise jurisdiction” for off-base offenses committed while US personnel are off duty, whereas the US retains primary jurisdiction for on-base crimes or incidents occurring while personnel are on duty. Both Tokyo and Washington view Okinawa as a critical strategic hub for deterring potential military aggression from China.

“The US and the Japanese governments have always cited the ‘geopolitical’ importance of the location of the archipelago to justify not only the presence itself but also the disproportionately high concentration of the US military there,” Akibayashi noted. “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.”

The professor pointed out that Okinawa accounts for 1 percent of Japan’s total population and under 1 percent of its territory. “Their political voice does not seem to bear significance to the Japanese government,” she added. “Probably more importantly, Okinawa was colonised by Japan in the late 19th century and has always been a subject of discrimination within Japan.”

Formerly an independent trading nation known as the Ryukyu Kingdom, Okinawa was annexed by Japan in 1879. The US later administered Okinawa—situated just 100 kilometres (60 miles) from Taiwan at its nearest point—from the conclusion of World War II until 1972.

“Many US military bases located on the main islands of Japan were transferred to the islands of Okinawa … because the mainland Japanese people had started to protest the presence of the US military in their neighbourhood,” Akibayashi explained.

The continuous presence of US marines has repeatedly fueled local resentment over disturbances such as noise, aircraft accidents, and misconduct by personnel.

Past incidents include a Japanese court sentencing a US marine last year to seven years in prison for choking and attempting to rape a woman in her 20s. In 2017, a former US marine and civilian military base worker received a life sentence for the rape and murder of a local woman in Okinawa. That same year, an intoxicated US marine collided with a mini-truck, resulting in the death of its 61-year-old local driver. Furthermore, the 1995 abduction and rape of a 12-year-old Okinawan girl by three US servicemen sparked massive demonstrations.

Data from the Yomiuri Shimbun newspaper indicates that approximately 6,000 US military personnel have faced arrest since Okinawa's return to Japanese control in 1972. Arrest numbers reached 80 in 2024, marking a 20-year high.

Akibayashi emphasized that Okinawans view these offenses as direct violations of their basic human rights. “Their lives and even survival have been made insecure and threatened by the US military presence,” she stated. “They have expressed countless times their opposition to and anger at the US military presence, and unequal burden of ‘security’ policies imposed on them throughout the decades. Their protests have been ignored and nullified.”

In response to Yagi’s murder, Japanese officials voiced profound indignation, while Washington promised complete cooperation with ongoing inquiries. Japanese Defence Minister Shinjiro Koizumi remarked, “Incidents and accidents involving US military personnel cause great anxiety among the local community and must not be allowed to happen.”

Prime Minister Takaichi reiterated that Japan lodged a formal protest with US authorities, labeling the offense “exceptionally brutal and vicious”. The administration has pressed the US “to provide maximum cooperation with the investigation, enforce stricter discipline among US military personnel, and take thorough measures to prevent the recurrence of similar crimes”, Takaichi added.

The US embassy and the Marine Corps offered condolences and affirmed their collaboration with Japanese authorities. In an official statement, the Marine Corps noted that the suspect—assigned to the III Marine Expeditionary Force and stationed at Marine Corps Air Station Futenma—remains 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.

Additionally, US Ambassador George Glass shared on social media that he communicated with Japan’s Ministry of Foreign Affairs and Okinawa’s governor, expressing “our sincere condolences and pledging full cooperation as the investigation continues”.

Nevertheless, Akibayashi observed that whenever crimes occur, “the US government and the military always say they would address the issue or promise tighter discipline. They never worked.”
