Dive-site story
What makes this site worth diving
US Navy air strikes sank the 158-meter Japanese auxiliary supply ship Kogyo Maru in September 1944 during Operation Hailstone's Coron raid. Resting on her starboard side in Coron Bay, the hull serves as an artificial reef covered in sponges and soft corals. Cargo holds contain airfield construction equipment, including a bulldozer, tractor, air compressors, and cement bags hardened underwater decades ago.

Plan this dive with care
- Wreck penetration requires dive lights and precise buoyancy control to prevent stirring up thick silt inside cargo holds.
- The profile reaches 34 meters at the seafloor, making bottom time and NDL monitoring critical.
