The tanker was anchored 8 kilometers north-northwest off Mutsurejima island in Shimonoseki, Yamaguchi Prefecture.

The Japan Coast Guard dispatched four patrol vessels and two aircraft.

According to the Coast Guard, nine of the 11 crew members, including Indonesians, were retrieved from the water by helicopter. Eight were confirmed dead, and one was alive.
