Kashi was one of four Momo-class destroyers built for the Imperial Japanese Navy (IJN) during World War I.

[2] The engines produced a total of 16,000 shaft horsepower (12,000 kW) that gave the ships a maximum speed of 31.5 knots (58.3 km/h; 36.2 mph).

[3] They carried enough fuel to give them a range of 2,400 nautical miles (4,400 km; 2,800 mi) at a speed of 15 knots (28 km/h; 17 mph).

[2] Kashi was transferred to the Manchukuo Imperial Navy on 1 May 1937 and was renamed Hai Wei (Chinese: 海威; pinyin: Hǎi Wēi).

[2] On 6 June 1942, Hai Wei was transferred back to the IJN, and reclassified as the auxiliary escort Kaii.
