''Nashi'' was sunk in July 1945, but salvaged in 1954 and refitted to join the Japan Maritime Self-Defense Force in 1956 as ''Wakaba'', later being utilised as a radar trials ship, but stricken in 1971 and scrapped in 1972–1973.
==Design and description== The ''Tachibana'' sub-class was a simplified version of the preceding ''Matsu'' class to make them even more suited for mass production. The ships measured {{convert|100|m|ftin|sp=us}} overall, with a beam of {{convert|9.35|m|ftin|sp=us}} and a draft of {{convert|3.37|m|ftin|sp=us}}.<ref name=g6>Sturton, p. 196</ref> They displaced {{convert|1309|t|LT|sp=us|lk=on}} at standard load and {{convert|1554|t|LT|sp=us}} at deep load.<ref>Whitley, p. 208</ref> 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 {{convert|19000|shp|lk=on}} for a speed of {{convert|27.8|kn|lk=in}}. They had a range of {{convert|4680|nmi|lk=in}} at {{convert|16|kn}}.<ref name=j3>Jentschura, Jung & Mickel, p. 153</ref>
The main armament of the ''Tachibana'' sub-class consisted of three Type 89 {{convert|127|mm|adj=on|0|sp=us}} 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. They carried a total of 25 Type 96 {{convert|25|mm|adj=on|0|sp=us}} anti-aircraft guns in 4 triple and 13 single mounts. The accuracy of the Type 89 guns was severely reduced against aircraft because no high-angle gunnery director was fitted. The ''Tachibana''s were equipped with Type 13 early-warning and Type 22 surface-search radars.<ref name=s1>Stille, p. 41</ref> The ships were also armed with a single rotating quadruple mount amidships for {{convert|610|mm|in|adj=on|0|sp=us}} torpedoes. They could deliver their 60 depth charges via two stern racks and two throwers.<ref name=g6/><ref name=s1/> Photos of her taken in drydock after her salvage showed that she had been equipped with a ramp at her stern designed to launch midget submarines.
==Construction and career== ''Nashi'' was launched by Kawasaki, Kobe, on 17 January 1945 and completed on 15 March.<ref name=j3/> She was assigned to Desron 11, Combined Fleet, for training on 15 March 1945. In May 1945 she was assigned to Destroyer Division 52, Cruiser-Destroyer Squadron 31. ''Nashi'' escaped an attack on Kure Harbour by B-29s on 22 June 1945, but on 28 July 1945 was sunk at Mitajirizaki, Kure ({{coord|34|14|N|132|30|E|display=inline}}) by aircraft from Halsey's Task Force 38. Commander Takeda and most of the crew survived.<ref>{{cite web |url=http://www.seaforces.org/marint/Japan-Maritime-Self-Defense-Force/Destroyer-Escort/DE-261-JDS-Wakaba.htm |title=DE 261 JDS Wakaba - Destroyer Escort - DE |work=Seaforces Online |access-date=25 July 2020}}</ref> On 15 September 1945, ''Nashi'' was officially struck from the Navy list.{{Citation needed|date=July 2020}}
The ship was refloated in 1954, and after repair at Kure recommissioned in the JMSDF as ''Wakaba'' on 31 May 1956. She was refitted in 1958 for use as a radar trials ship, and sonar was added in 1960. As such, she was the only ship of the Imperial Japanese Navy to become part of the post-war Japan Maritime Self-Defense Force, and for some time was the biggest ship in the JMSDF.{{Citation needed|date=July 2020}}
''Wakaba'' was struck on 31 March 1971, and scrapped in 1972–1973.
== Name == 'Nashi' is a type of pear. 'Wakaba' means "Young Leaves" in Japanese, suggesting the "green shoots" of recovery, a symbol of a new start after the war. Additionally, while the name 'Nashi' in the logographic Japanese Kanji script unmistakably means: 'pear' (梨), in the phonetic Japanese script of Hiragana, 'Nashi (なし)' can mean "Not exist". Therefore, to avoid misunderstanding the term: "Not exist" (over radio or other communication) she was renamed.{{Citation needed|date=July 2020}}
