A sports fishing boat capsized and sank Wednesday morning after colliding with a Maritime Self-Defense Force transport ship in the Seto Inland Sea off Otake, Hiroshima Prefecture, leaving two of the four men on board the leisure craft in critical condition, the Defense Ministry and the Japan Coast Guard said.

The owner of the boat and three other anglers were thrown into the water in the collision, which occurred at around 8 a.m.

They were rescued by the MSDF vessel, the 180-meter-long tank landing ship Osumi.
