All 12 seafarers have been rescued after abandoning a listing ro-ro that hit an underwater rock off southern Japan.

Broadcaster NHK reported that the accident involving the 2,200-lane-metre Suou (built 2019) happened in the early hours of Tuesday off the city of Matsuyama.

The crew members took to life rafts and were picked up by a coastguard patrol boat about 90 minutes later.
