Who was Anna Yagi, and why was a U.S. Marine indicted in Okinawa? On Oct. 25, 2026, prosecutors in Okinawa, Japan, indicted a 20-year-old U.S. Marine on a charge of robbery causing death in the Oct. 3 death of Anna Yagi, 39, at a hotel in Naha. He has denied the allegations, according to Okinawa police, and is presumed innocent. We do not name him: he is charged, not convicted.

What we don't know

  • What the evidence shows beyond what prosecutors have said.
  • How the two knew each other, if at all. Police and prosecutors haven't said.
  • When a court will hear the case. No trial date has been announced.
  • Reports differ on some details (where exactly he was arrested, the time she was found), so we leave them out.

What happens next

The case goes to trial in Japan; no date has been set. We will post a dated update here when the court sets one or the case moves.
