The largest wreck in the lagoon at 155m (510ft), the Heian Maru was built in 1930 as a passenger cargo ship. Recalled to Japan during a normal voyage between Hong Kong and Seattle in 1941 she was then converted to a submarine tender. Her name is found in English and Japanese on the hull and she was named after the ancient city of Heinkyo, “The City of Peace and Tranquility.”

Artifacts have also been gathered from inside the ship and placed together including a fantastic medical kit with several different colored bottles.
