History

[edit]

She was laid down on 18 January 1944 at the Takamatsu shipyard of Shikoku Dock Industry Co., Ltd. (株式會社四国船渠工業所) and launched on 3 July 1944.[1][2] She was completed and commissioned on 28 August 1944,[2] fitted with armaments at the Kure Naval Arsenal, and assigned to the Kii Defense Unit, Osaka Guard District under commanding officer Teruo Takeuchi.[2] She mostly conducted patrol and escort duties out of the port of Yura, Wakayama.[2] On 6 May 1945, she was attacked and damaged by two Consolidated B-24 Liberators off Komatsushima.[2] She was repaired at Osaka in June 1945.[2] Cha-221 survived the war.[2]

On 1 December 1945, she was demobilized and enrolled as a minesweeper by the occupation forces.[2] On 1 January 1948, she was released to the Ministry of Transportation.[2] On 1 May 1948, she was assigned to the Japan Maritime Safety Agency, a sub-agency of the Ministry of Transportation, and designated Minesweeper No. 221 (MS-02) on 20 August 1948.[2] On 1 December 1951, she was renamed Yoshikiri (MS-02) (よしきり).[2] On 1 July 1954, she was transferred to the newly created Japan Maritime Self-Defense Force and designated as Yoshikiri (MS-02) and later MSI-690.[2] She was delisted on 31 March 1962.[2]
