A US Marine just got arrested in Okinawa.
He's accused of robbing and killing a Japanese woman at a hotel.
And Japan's government just filed a formal protest over it.
So here's what happened.
Lance Cpl. Devin Jacob Ballard is 20 years old. He's based at Marine Corps Air Station Futenma, with the III Marine Expeditionary Force.
Police arrested him at 1am local time, two days ago.
They say he robbed and killed Anna Yagi. She was 39, from Naha. She died at a hotel in the city, some time between 2:10am and 4:17am that same night.
Police say CCTV shows Yagi walking into the hotel with a man. They've identified that man as Ballard. The footage then shows him leaving alone.
A hotel worker found Yagi unconscious after the pair didn't check out. They called the fire department. Police say Ballard stole her wallet and one other item.
According to two of the outlets that reported this, officers spotted a man matching the suspect's description walking in an Okinawa nightlife district the night after the killing. They questioned him. Then they arrested him.
Ballard denies the allegations.
Police expect to refer the case to prosecutors within 48 hours of the arrest.
So what has Japan said?
Sanae Takaichi, Japan's Prime Minister, says Japan has lodged a strong protest with the United States. She called the killing exceptionally brutal and vicious. She's demanding full cooperation with the investigation, stricter discipline for US troops in Japan, and steps to stop this happening again.
Japan's Ministry of Defense says it is deeply outraged. Same demands — stricter discipline, and measures to prevent it happening again.
Shinjiro Koizumi, Japan's Defence Minister, called it unacceptable. He says he feels deep anger.

Genta Koja is Okinawa's governor. He called the case unforgivable. He says discipline and training for US troops on the island are not working.
That's Okinawa's own governor saying the system has failed.
So what does the US side say?
George Glass, the US Ambassador to Japan, says he's spoken with Japan's foreign ministry and with Governor Koja. He's pledged full cooperation. He's offered condolences to Yagi's family.
The US Embassy in Tokyo says it is communicating and cooperating with the Japanese government and local authorities. It has also offered condolences.
The III Marine Expeditionary Force says it's cooperating with Japanese authorities. 1st Lt. Tyler Thomas, a Marine Corps officer, says quote "the Marine Corps takes these allegations very seriously and expects every Marine to adhere to the highest standards of behavior".
Yagi's brother spoke through police. He says his family is deeply saddened, and that his parents are utterly devastated at the loss of their daughter.
And here's the thing. This isn't new for Okinawa.
Around 54,000 US troops are based in Japan. Most of them are on Okinawa. America held the island from the end of the Second World War until 1972. Its bases have caused tension with local people ever since.
Arrests involving US troops and their families on Okinawa topped 100 last year, according to prefectural police.
Last year, a Japanese court gave a US Marine seven years for choking and attempting to rape a woman in her twenties. In 2017, a former Marine and civilian base worker was sentenced to life for raping and killing a local woman, Rina Shimabukuro. In 1995, three US servicemen raped a 12-year-old Okinawan girl. That set off mass protests against the American presence on the island.
So what don't we know?
What led to Yagi's death beyond the alleged robbery isn't known. Whether Ballard and Yagi knew each other, or how they ended up at the hotel together, hasn't been explained by police. Whether more charges will be filed is also not known.
One more thing is unclear. Reports don't agree on which Japanese official formally lodged the protest with Ambassador Glass, and that hasn't been resolved.
For now, Ballard is in Japanese custody, denying the charges. And Japan's government is saying, once again, that its trust in US military discipline on Okinawa has been broken.
