Following the arrest of U.S. Marine Lance Corporal Devin Jacob Ballard on suspicion of the robbery and murder of 39-year-old Anna Yagi at a Naha hotel, the U.S. military in Okinawa has implemented strict disciplinary measures.

Lt. Gen. Benjamin Watson, commander of the III Marine Expeditionary Force, ordered a 48-hour operational pause beginning at noon on October 7. During this suspension, personnel are prohibited from consuming alcohol and engaging in off-base liberty. The military stated this period will be used for training on standards, discipline, and community responsibility, and they have pledged to cooperate fully with Japanese investigations. The military also plans to present revised rules regarding off-base activities to the Okinawa Regional Coordination Committee.

Following the 48-hour pause, a 30-day reflection period is being enforced, which includes a nightly curfew from midnight to 5 a.m. for all U.S. personnel in Okinawa and increased security at base entrances. On the night of October 10 and the early morning of October 11, U.S. military police conducted safety patrols in the entertainment district near Gate Street in Okinawa City. During these patrols, military police detained two men believed to be affiliated with the military for allegedly violating nighttime curfew regulations.

The incident has prompted formal protests from the Japanese government, with Prime Minister Sanae Takaichi describing the crime as “extremely brutal and heinous,” and Okinawa Governor Genta Koja demanding a review of the Japan-U.S. Status of Forces Agreement (SOFA).
