Japan’s Supreme Court has dismissed a U.S. airman’s appeal against his five-year prison sentence for kidnapping and sexually assaulting an underage girl in Okinawa Prefecture.

The decision, issued by the top court’s Second Petty Bench on Friday, finalizes the sentence for Brennon Washington, a 26-year-old service member at Kadena Air Base in the prefecture.

According to the district and high court rulings, Washington drove the victim to his home in December 2023 and sexually assaulted her, knowing the girl was under 16 at the time.

While the defense pleaded not guilty, the Naha District Court found the defendant guilty in December 2024, saying that the victim’s claim of damage was fairly credible.

In September 2025, the Naha branch of the Fukuoka High Court upheld the district court’s ruling and dismissed Washington’s appeal.
