There had been quite some confusion for a while about the true name of Okikawa Maru. Some called it Taiei Maru, but researches proved that this ship was already sunk by a submarine in August 1944. To further increase the confusion, the site is also known as Concepcion Wreck (due to its location).
The Okikawa Maru with its length of 160m is the largest of the Coron wrecks. It is richly covered with hard and soft corals, sponges and hydroids, giving home to various species of fish, like sweetlips, groupers, wrasses, soldier fish, lionfish and many more.
The Okikawa Maru is lying upright in a depth of 26 m, the bow area is nearly completely ripped off and twisted facing to the port side. The main deck area is in a depth of between 10 to 15m, which allows longer dives and makes it suitable also for beginners.
For more advanced wreck divers there are some areas where penetration is possible to explore the inside of the ship. One point is through the propeller shaft and up to the engine room. Another one is a cargo hold on top of the deck, an impressive swim through and coming out at the twisted bow section.
The wreck is located in a channel, so there can be currents, specially towards the stern. But there are still enough current protected areas around the superstructure to enjoy the dive.
