Watch: South Korean-flagged tanker capsizes in rough seas off the coast of Japan
Eight people have been confirmed dead after a South Korean-flagged tanker capsized off the west coast of Japan.
One other person was found in a non-life-threatening condition while two others remain missing, Japan's coast guard said.
Aerial footage shows the overturned Keoyoung Sun vessel and a life-raft in the sea as the Japan coastguard launches a rescue operation to find survivors.
The tanker capsized off Yamaguchi prefecture after the crew radioed for help around 07:00 on Wednesday (22:00 GMT Tuesday).
