Momi (樅, translation: "White fir") was a Matsu-class destroyer of the Imperial Japanese Navy (IJN) built during World War II.

Completed in late 1944, the ship was designed as an anti-submarine escort and defended convoys between Japan and its occupied territories during the war.

Designed for ease of production, the Matsu class was smaller, slower and more lightly armed than previous destroyers as the IJN intended them for second-line duties like escorting convoys, releasing the larger ships for missions with the fleet.

Between 25 October and 2 November, together with the destroyer Hinoki, she escorted the aircraft carriers Ryūhō and Kaiyō on a transport mission from Sasebo to Keelung, Japanese Taiwan, then returned to Kure.

Because an American invasion fleet had been spotted approaching the Philippine Islands, Unryū was intended to deliver a squadron of 30 Ohka kamikaze planes to Manila.

From there the pair escorted the ex-Italian reefer ship Ikutagawa Maru from Cape St. Jacques to Manila, arriving on 4 January 1945.

[9][11] The following day the trio attempted to leave Manila for Indochina despite the presence of a nearby Allied convoy headed towards Lingayen Gulf.

By this time, Bennion was 30 nautical miles (56 km; 35 mi) from its convoy and had expended 349 five-inch rounds without scoring a single hit.
