Nissan Maru began civilian service as a cargo vessel. On July 19, 1939 while steaming down the Whangpoo River at Shanghai accidentally collided with SS President Coolidge tied up at a pier without injuries aboard either ship. The bow of Nissan Maru was damaged and later repaired. At the start of World War II, Japanese flag was painted amidships designating the vessel as flagged to a neutral nation.

On September 20, 1941 registered as an auxiliary collier/oiler attached to the Maizuru Naval District at Maizuru and the same day assigned to the 5th Fleet under the supervision of Captain Takao Sakuma. Four days later, began a conversion into Koshin Maru-class Auxiliary Transport at Osaka Iron Works K.K. for use as a collier/oiler and was ready by the middle of October 1941.

Sinking History
On June 19, 1942 at 5:00am again bombed by three B-17s and four B-24s plus a single LB-30 and is again hit by bombs and sinks at 7:00am at roughly Lat 52° 30' N, Long 176° 30' E into Kiska Harbor. On June 21, 1942 the sunken ship was confirmed by U.S. photographic reconnaissance. On July 1, 1942 officially removed from the Navy list.

The bow of the shipwreck is partially above the surface of Kiska Harbor with the name of the vessel in kanji and the letters "N A" of Nissan Maru. On the bow is the 3" gun on a ten sided mount.

The bow has a 76.2mm deck guns on ten-sided gun mount with ammunition boxes nearby with their lids still closed reflecting the sudden air attack that sank the vessel. The stern has another 76.2mm gun on a ten sided mount. The telegraph in place, but the binnacle has been removed, probably by SCUBA divers in recent years.
