She was laid down on 26 August 1944 at the Ujiyamada shipyard of Nishii Shipyards (西井=西井造船所) and launched in 1944.[1][2] She was fitted with armaments at the Yokosuka Naval Arsenal, completed and commissioned on 31 December 1944, and assigned to the Sasebo Guard Force.[2] On 15 May 1945, she was assigned to the Shimonoseki Defense Team.[2] Cha-232 survived the war.[2]

On 30 December 1945, she was demobilized and enrolled as a minesweeper by the occupation forces operating out of Shimonoseki.[2] On 28 August 1947, she was assigned to the Japan Maritime Safety Agency and on 20 August 1948 she was designated as a patrol boat (PB-09) and renamed Ōtaka.[2] On 1 July 1950, she was re-designated as PS-09 and on 1 August 1951 as minesweeper MS-86.[2] On 1 July 1954, she was transferred to the newly created Japan Maritime Self-Defense Force.[2] On 1 April 1956, she was re-designated Special Boat No. 10 (MS-86).[2] She was delisted on 31 March 1957.[2]
