Ship History
Originally, she was a three deck passenger ship designed for luxury service between Yokohama and Seattle.

Sinking History
USS Yorktown planes hit the ship and started fires aboard the vessel. It smoldered and was attacked all day until it finally sank in Truk Lagoon on February 17, 1944.

Shipwreck
Large 18" Roman letters spelling out "Heian" are still visible on the forward hull with the Japanese Kanji above it. Ammunition, guns, torpedo and submarine parts are among lots of debris. Exploration of the ship is difficult form its sideways orientation.

Dan E. Bailey adds:
"The most interesting artifact I have seen is an optical signaling device. It is a rare find and its presence on the ship belies the importance of the Heian Maru as a sub-tender for the 6th Submarine Fleet."
