The Japanese destroyer Kaki (柿) was one of 21 Momi-class destroyers built for the Imperial Japanese Navy (IJN) in the late 1910s. She was converted to a training ship and survived the Pacific War as an auxiliary ship and was subsequently scrapped in 1948.

The Momi class was designed with higher speed and better seakeeping than the preceding Enoki-class second-class destroyers.^[1] The ships had an overall length of 280 feet (85.3 m) and were 275 feet (83.8 m) between perpendiculars. They had a beam of 26 feet (7.9 m), and a mean draft of 8 feet (2.4 m). The Momi-class ships displaced 850 long tons (864 t) at standard load and 1,020 long tons (1,036 t) at deep load.^[2] Kaki was powered by two Parsons geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers.^[3] The turbines were designed to produce 21,500 shaft horsepower (16,000 kW) to give the ships a speed of 36 knots (67 km/h; 41 mph). The ships carried a maximum of 275 long tons (279 t) of fuel oil which gave them a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 15 knots (28 km/h; 17 mph). Their crew consisted of 110 officers and crewmen.^[4]

The main armament of the Momi-class ships consisted of three 12-centimeter (4.7 in) Type 3 guns in single mounts; one gun forward of the well deck, one between the two funnels, and the last gun atop the aft superstructure. The guns were numbered '1' to '3' from front to rear. The ships carried two above-water twin sets of 533-millimeter (21 in) torpedo tubes; one mount was in the well deck between the forward superstructure and the bow gun and the other between the aft funnel and aft superstructure.^[2]

Kaki, built at the Uraga Dock Company in Uraga, Japan, was launched on October 20, 1919, and completed on August 2, 1920. She was decommissioned on April 1, 1940, before being converted to a training ship. The ship was then re-converted to a auxiliary ship and was renamed Ōsu (大須). She served in that capacity throughout the Pacific War before being finally scrapped in 1948.
