About this site
Yamagiri Maru is a large cargo ship that was carrying artillery shells when it was sunk during Operation Hailstone. It now rests at depths of 30 to 40 metres (100 to 130 feet), with its cargo still visible in the holds.
The holds are filled with massive artillery shells, some nearly six feet long, covered in corals. The engine room is accessible to technical divers, and the bridge and superstructure are largely intact, covered in soft corals and sponges.
Large schools of fish gather here, and the occasional shark passes. The depth and location make it a less frequented wreck.
