[1] On 12 December 1997, TSUSHIMA MARU was positively identified by Dolphin 3K deep sea detection equipment at a depth of 2, 858 feet (871 m), 6 miles NW of Akuseki Island, Kagoshima Prefecture. Portions of the vessel were video taped and the ship's name was found painted on the hull.

[2] Corbus claims four other ships sunk, but postwar, the claim is not substantiated.

Little data were found about HASU's movements during Feb-Oct '42. Readers with access to such data are requested to post the information on the Discussion and Questions board or j-aircraft.org's IJN Ship Message Board
