Japanese Prime Minister Sanae Takaichi condemned the murder of a 39-year-old woman in Naha, Okinawa, on Monday, following the arrest of a U.
S. Marine.
The case has intensified public anger across Japan over crimes linked to American military personnel.
Authorities arrested 20-year-old Lance Cpl. Devin Jacob Ballard, a U.
S.
Marine stationed at Futenma Air Station, on suspicion of killing Anna Yagi at a hotel early Saturday and stealing her wallet and backpack.
Japanese media reported that Ballard denied the allegations.
Investigation sources told public broadcaster NHK that security footage from the scene depicted a foreign man entering a room with a woman before departing with her belongings.
Officers later located a suspect in an entertainment district roughly 15 miles northeast of Naha whose shaved head and arm tattoos matched the footage.
Addressing lawmakers on Monday, Prime Minister Takaichi stated that Japan lodged a formal protest with U. S.
officials while demanding full investigative cooperation and strict military discipline.
"The occurrence of such a heinous crime is extremely regrettable," Takaichi said.
Japanese prosecutors began examining the case on Monday to evaluate potential formal charges, which could carry life imprisonment or the death penalty upon conviction.
In Naha, approximately 100 demonstrators gathered on Sunday to protest the killing, while a similar demonstration took place in Tokyo.
University student Sorane Sakihama, a 24-year-old Okinawa native who organized the Tokyo rally, expressed frustration over the military presence.
"We couldn't protect her. That made me so angry and sad," Sakihama said.
Sakihama noted plans to host another demonstration outside the U. S.
Embassy.
"I want to ask them — what are these soldiers stationed here for? They might say they are here to protect lives or boost security.
But how can they say that when a life was taken by their own?" Sakihama said.
Government officials confirmed that Japanese foreign affairs and defense ministers summoned senior U. S.
representatives to register extreme disappointment immediately after the arrest.
Chief Cabinet Secretary Minoru Kihara outlined the government's stance during a press conference on Monday.
"The government will work with the United States to thoroughly make sure there will be no recurrence, and reduce burdens on local residents," Kihara said.
Okinawa Governor Genta Koja emphasized the emotional impact of the incident on local communities already hosting 70% of U.
S. military facilities in Japan.
"Hugely shocked residents here who are forced to live side-by-side with the bases, and instilled new fear in them," Koja said.
Koja criticized existing institutional measures intended to maintain order among service members.
"I am infuriated," Koja said.
The governor noted that local preventative efforts have proven inadequate.
"Educate soldiers and improve their behavior have not been functioning at all," Koja said.
U. S.
Ambassador to Japan George Glass addressed the situation on social media on Monday, confirming conversations with Lt. Gen.
Benjamin Watson regarding military standards.
Glass stated he advised military commanders on the need "to hold our American service members to the very highest levels of discipline and integrity."
Glass added that discussions focused on the "next steps in strengthening that bond of trust with our Japanese partners and base-hosting communities."
Because the suspect was off duty during the incident and apprehended off base, Japanese authorities are processing the case under the bilateral Status of Forces Agreement.
