History
editHer construction was authorized under the Maru Sen Programme (Ship # 2001–2100). She was laid down on 26 November 1943 as ship 2053 at the Murakami Shipyard (村上造船所) in Ishinomaki[1] and launched on 15 June 1944.[2]
She was completed and commissioned on 14 October 1944,[2] fitted with armaments at the Yokosuka Naval Arsenal, and assigned to the Ōminato Guard District under lieutenant Keio Ebisawa (海老澤 経男).[2] On 1 November 1944, she was assigned to the Tsugaru Defense Force and tasked with defending the Tsugaru Strait.[2] She spent most of the war conducting anti-submarine and minesweeping patrols between the ports of Hachinohe, Hakodate, and Muroran.[2] Cha-203 survived the war and was decommissioned on 20 November 1945.[2][3]
On 1 December 1945, she was enrolled as a minesweeper by the occupation forces,[2] one of 269 Japanese ships that served as a minesweeper under the Allied forces after the war.[4] She conducted minesweeping operations based out of Ominato and later Shimonoseki.[2] On 1 August 1947, she was demobilized[2] and on 28 August 1947, 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 on 20 August 1948 as patrol vessel Hiyodori (ひよどり) (PB-22).[2] On 21 July 1950, she was re-designated as patrol vessel Hiyodori (PS-22) and on 1 December 1951 she was redesignated as minesweeper Hiyodori (MS-84).[2] On 1 August 1952, she was assigned to the Coastal Safety Force.[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 minesweeper inshore Hiyodori (MSI-700).[2][5] She was delisted on 31 March 1965.[2]
