Two cargo ships have collided off Tokyo leaving five Japanese crew members critically injured, and another missing.
The five sailors rescued on Friday evening from the Japanese-flagged Eifuku Maru No 18 were found in a state of cardiorespiratory arrest, the Japan Coast Guard said.
The coast guard was searching for the sixth crew member, the Kyodo News Agency reported.
The 498-tonne ship and the 2,962-tonne Jia Hui, registered in Sierra Leone, collided at about 1.25am on Friday near Izu Oshima island, 100km south of Tokyo.
The Japanese vessel, found capsized with all its crew missing, was heading for Chiba, east of Tokyo, from Nagoya, central Japan.
The 13 Chinese and Myanmar nationals that made up the Sierra Leone freighter’s crew were rescued from waters nearby, Kyodo said.
The Jia Hui was on its way to Busan, South Korea, from Kawasaki, south of Tokyo.
