Japan Protests After U.S. Marine Arrested in Okinawa Woman’s Death

Japan has lodged a formal protest with the United States after a 20-year-old U.S. Marine was arrested in connection with the death of a woman in Okinawa, a case that could reignite long-standing anger over the heavy American military presence on the island.

Devin J. Ballard, a lance corporal assigned to the III Marine Expeditionary Force, is being held by authorities in Naha, the capital of Okinawa Prefecture. Japanese police suspect Ballard of robbing and killing 39-year-old Anna Yagi, who was found unconscious at a hotel in the city’s Wakasa district early Saturday morning.

Ballard has denied the allegations, according to police.

Japanese media reported that surveillance footage showed Ballard entering the Naminoue Crystal Hotel with Yagi in the early hours of Saturday. Police said Ballard allegedly left the hotel alone sometime later. A hotel employee later called emergency services after finding Yagi unconscious.

Authorities suspect Ballard stole Yagi’s wallet and another item and killed her sometime between 2:10 a.m. and 4:17 a.m. Saturday. He was arrested the following night while walking in an Okinawa nightlife district.

The U.S. Embassy in Tokyo said American officials are cooperating with Japanese authorities.

“We extend our sincere condolences to the victim’s family,” the embassy said in a statement.

Japan’s Foreign Ministry said Foreign Minister Toshimitsu Motegi lodged a “strong protest” with the U.S. side, calling the incident “extremely brutal and heinous” and “extremely regrettable.”

Motegi urged the United States to fully cooperate with the investigation and called on American military officials to strengthen discipline and prevent similar incidents from happening again.

Defense Minister Shinjiro Koizumi also condemned the alleged crime, saying the incident was “unacceptable” and that he was “deeply outraged.”

Prime Minister Sanae Takaichi said Japan expects “maximum cooperation” from the United States as the investigation moves forward.

The case is especially sensitive because Okinawa hosts a large share of U.S. forces stationed in Japan. Roughly 30,000 active-duty U.S. military personnel are based in the southern prefecture, which has long been a flashpoint for anti-base protests and local resentment.

The United States seized Okinawa from Japan during World War II and returned it to Japanese control in 1972, but American bases have remained a major presence on the island. Critics have long argued that Okinawa bears an unfair burden for hosting U.S. military facilities, while supporters of the alliance say the bases are strategically vital, especially given Okinawa’s proximity to Taiwan and China.

The arrest could complicate ongoing plans involving the relocation of some Marines from the Futenma air base to a more remote facility at Henoko, a project that has faced years of local opposition.

The case also recalls previous crimes involving U.S. military personnel or contractors in Okinawa. In 2017, Kenneth Franklin Shinzato, a former U.S. Marine who was working as a civilian contractor, was sentenced to life in prison for the rape and murder of 20-year-old Rina Shimabukuro.

Japanese police have reportedly assigned a 200-member investigative team to the latest case. Ballard remained in Japanese custody Sunday, and authorities were expected to refer the case to the Naha Public Prosecutors Office within 48 hours of his arrest.
