History
She was laid down on 13 January 1944 at the Tokushima shipyard of Tokushima Joint Shipbuilding Co., Ltd. (徳島合同造船株式會社) and launched later in the year.[1][2] She was completed and commissioned on 15 August 1944,[2] fitted with armaments at the Kure Naval Arsenal, and assigned to the Saiki Defense Unit, Kure Naval District.[2] In December 1944, Captain Shunji Inuchi (井内 俊治) was appointed as commanding officer and on 10 June 1945, she was assigned to the Tokuyama Defense Force, Kure Naval District.[2]
She mostly conducted patrol and minesweeping duties in and around Saiki, Ōita and later Tokuyama.[2] Cha-215 survived the war and was decommissioned on 30 November 1945.[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 20 August 1948, she was assigned to the Japan Maritime Safety Agency, a sub-agency of the Ministry of Transportation, and designated on 20 August 1948 as Minesweeper No. 215 (MS-16).[2] On 20 October 1949, she was re-designated as Minesweeper Special No. 215 (MS-16) and on 1 December 1951 she was assigned the name Tomozuru (ともづる) (MS-16).[2] On 1 July 1954, she was transferred to the newly created Japan Maritime Self-Defense Force and re-designated on 1 September 1957 as Tomozuru (MSI-693).[2] She was delisted on 31 March 1962.[2]
