Sarushima (猿島) was a small Natsushima-class minelayer of the Imperial Japanese Navy, which was in service during World War II.
Sarushima was a slightly enlarged version of the Natsushima class, with the same armament, but with diesel engines.
Sarushima was launched by the Mitsubishi Yokohama shipyards on December 16, 1933, and was commissioned into service on July 20, 1934.
At the time of the attack on Pearl Harbor in December 1941, Sarushima was assigned to the Yokosuka Guard District, remaining in Japanese home waters for most of the duration of the war, and occasionally escorting convoys to the Bonin Islands.
On April 15, 1944, Sarushima departed Tokyo with a convoy for Saipan, returning safety on May 4.
