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.[1] The ships measured 100m (300feet) long overall, with a beam of 9.35m (30.68feet) and a draft of 3.3m (10.8feet).[2] Their crew numbered 210 officers and enlisted men.[3] They displaced 1282sp=usNaNsp=us at standard load and 1554t at deep load.[4] The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by two Kampon water-tube boilers. The turbines were rated at a total of 19000shp for a speed of 27.8kn. The Matsus had a range of 4680nmi at .[5]
The main armament of the Matsu-class ships consisted of three 1270NaN0 Type 89 dual-purpose guns in one twin-gun mount aft and one single mount forward of the superstructure. The single mount was partially protected against spray by a gun shield. The accuracy of the Type 89 guns was severely reduced against aircraft because no high-angle gunnery director was fitted. The ships carried a total of twenty-five 250NaN0 Type 96 anti-aircraft guns in 4 triple and 13 single mounts. The Matsus were equipped with Type 13 early-warning and Type 22 surface-search radars.[6] The ships were also armed with a single rotating quadruple mount amidships for 610mm torpedoes. They could deliver their 36 depth charges via two stern rails and two throwers.[2] [6]
Authorized in the late 1942 Modified 5th Naval Armaments Supplement Program,[7] Sakura (cherry blossom) was laid down on 2 June 1944 at the Yokosuka Naval Arsenal and launched on 6 September.[8] Upon her completion on 25 November, the ship was assigned to Destroyer Squadron 11 of the Combined Fleet for training. On 12 February 1945, Sakura departed Moji as part of the escort for Convoy MOTA-36 bound for Keelung, Taiwan. She then escorted the cruiser to Shanghai, China and remained in the area, tasked with patrol and escort duties. On 15 March the ship was reassigned to the squadron's Destroyer Division 53. Six days later Sakura arrived at Kure, Japan. The squadron was briefly attached to the Second Fleet from 1–20 April before rejoining the Combined Fleet.[9]
Sakura was slightly damaged when she struck a mine in Shimonoseki Strait between Kyushu and Honshu on 25 May. The ship was tasked with minesweeping duties the following month. When she struck a mine on 11 July in Osaka Harbor, her aft magazine exploded, severing her stern. The ship sank at coordinates 34.6°N 163°W with the loss of 130 crewmen. Sakura was removed from the navy list on 10 August.[9]
