Okikawa Maru wreck dive is the largest of all the wreck dives in the Coron Bay area and is a dive site with many things for divers to do. The Okikawa Maru was a 168-meter long Japanese tanker that now provides divers with many different possibilities for wreck penetration diving. There can be strong currents on this wreck but that does provide for divers to be able to see more ocean life as more fish come to the wreck to feed.

The wreck is covered with beautiful corals and the deck is only at 10 to 16 meters making it a great dive for beginner divers but it also means that divers can have a longer dive on the wreck.

Divers will be able to penetrate up the propeller shaft, and make their way through the ship into the engine room. The engine room is empty apart from two boilers but it is an amazing place to dive as the light fills the room making it a surreal experience.

Marine life includes schools of snappers, batfish, and a resident grouper at the bottom of the boat. There are sponges, large lettuce corals, and puffer fish, scorpion fish, and lionfish. Macro divers will also be kept busy, as there are many different types of nudibranchs, and other smaller creatures.
