Eight sailors have died after a South Korean-flagged tanker overturned 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.

It's not clear yet what the tanker was carrying.

This tanker is known for carrying oil and chemicals, according to shipping information websites.

The efforts to save the crew happened near Shimonoseki city.

Reports say the tanker's crew included two people from Korea, eight from Indonesia, and one from China.

The wind was blowing really hard in the area on Wednesday, going as fast as 54 kilometers (33 miles) per hour.
