A motorcyclist died over the weekend after colliding with a vehicle driven by an unidentified U.S. sailor stationed at Yokosuka Naval Base, according to Japanese police.

The sailor’s vehicle struck the motorcycle around 6:50 p.m. Sunday at an intersection in Heisei-cho, southeast of the base, a Yokosuka police spokesman said by phone the next day.

The motorcyclist — a man whom the spokesman declined to identify — was pronounced dead at a nearby hospital at 7:53 p.m.

The sailor’s vehicle was making a right turn when it collided with the motorcycle, which was traveling straight through the intersection, the spokesman said.

It’s customary in Japan that some government officials speak to the media on the condition of anonymity.

Spokespeople for the base and Naval Forces Japan did not immediately respond to a request for comment Monday afternoon.

The death marks the second fatal motorcycle accident involving a U.S. sailor in Yokosuka since September.

Llano Jaden Edwin, 22, was charged March 6 with negligent driving causing death in the Sept. 18 collision.

Japanese prosecutors allege the USS Blue Ridge sailor made an illegal right turn at a five-way intersection near the base and struck a 22-year-old motorcyclist.

Edwin is scheduled to appear May 7 at Yokohama District Court in Yokosuka.
