The origin of this cargo vessel is not known, probably built in Europe, captured and used
by the Japanese Fleet. This freighter was sunk on 24 September 1944 by US aircraft, the wreck - 129m (425ft) long, 6,352 gross tons - lies on its starboard side pointing 230 degrees (compass bearing) in 36m (119ft) of water. The port-side hull is at 22m (72ft). A bulldozer and a cement mixer with about 1000 cement bags lies in one of the cargo holes at 30m (99ft) depth. In another cargo hole are still other construction supplies.
The Kogyo Maru is well covered with good corals, particularly very large lettuce corals, shoals of fish including fusiliers, snappers and batfish, plus the ubiquitous lionfish and
scorpionfish.
