Japan's government has protested to the United States and summoned the US ambassador in Tokyo over the killing of a 39-year-old Japanese woman on Okinawa, in which a US marine is suspected, according to TASS, RBC and Kommersant. TASS reported that Foreign Minister Toshimitsu Moteqi summoned the US ambassador and called on the American side to give full cooperation to the investigation; Kommersant named the ambassador as George Glass and said the minister also demanded stronger discipline among US service members stationed in the country. Kommersant reported that Prime Minister Sanae Takaichi wrote on X that the incident was monstrous and a cause of deep regret, that the Japanese government was lodging a resolute protest, and that she demanded the US military command tighten discipline and take exhaustive measures to prevent similar incidents.

Okinawa police detained a 20-year-old US serviceman, Devin Ballard, Kommersant reported. According to the investigation, as described by the outlet, on 3 October he killed a 39-year-old Japanese citizen at a hotel in the city of Naha and then stole her purse and backpack. Kommersant said the American did not admit guilt. RBC, publishing earlier, reported only that a marine had been arrested on suspicion of robbing and killing a 39-year-old woman at a hotel on Okinawa. [ 2 , 4 ]
Kommersant reported that the US Embassy and the Marine Corps command expressed condolences over the incident and said they were cooperating with Japanese authorities, and that the Marine Corps said it takes the accusations seriously and expects every marine to uphold the highest standards of conduct. TASS reported that the US Marine Corps on Okinawa published a statement expressing its deepest condolences to the family of the deceased. [ 1 , 4 ]
Kommersant placed the case in the context of the US military presence on Okinawa, reporting that most of the 18,000 US service members stationed in Japan are based there, that the presence has repeatedly prompted protests by local residents over crimes, noise and aircraft accidents, and that Okinawa covers 0.6% of Japan's territory but accounts for 74% of the area of US bases in the country. The outlet also recalled that in June 2025 the Naha district court sentenced a US marine to seven years in prison for attempted rape of a local resident, and that in a January 2026 publication Japanese media reported four cases of attempted rape by US military personnel on Okinawa over the previous year.

The accounts differ in emphasis rather than substance: TASS and Kommersant focus on the foreign ministry's summoning of the ambassador and the demand for cooperation and discipline, while Kommersant additionally attributes the protest statement to the prime minister and provides the criminal details. The documents do not say what charges the marine faces, where he is being held, or whether Washington has responded beyond expressions of condolence and pledges of cooperation. [ 3 , 4 , 5 ]
Why it matters
The case involves a US service member and a Japanese resident on Okinawa, and Japan's prime minister and foreign ministry have both raised it with Washington, moving the incident into a bilateral channel between the two governments. Kommersant linked the case to the long-running local dispute over the concentration of US bases on the island, where it said the American presence has repeatedly drawn protests. The documents give no basis for judging what consequences, if any, will follow for the two governments.
