Cha-196 or No. 196 (Japanese: 第百九十六號驅潜特務艇) was a No.1-class auxiliary submarine chaser of the Imperial Japanese Navy that served during World War II and with Japan during the post-war period.

History

Her construction was authorized under the Maru Sen Programme (Ship # 2001–2100). She was laid down on 6 March 1944 as ship 2046 at the Yamanishi Shipbuilding Iron Works (jp:ヤマニシ) in Ishinomaki[1] and launched on 8 August 1944.[2]

She was completed and commissioned on 15 October 1944,[2] fitted with armaments at the Yokosuka Naval Arsenal, and assigned to the Ōminato Guard District under lieutenant Mitsuharu Haneda (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 from the port of Muroran.[2] On 26 June 1945, she was assigned to the Maizuru Naval District.[2] Cha-196 survived the war and was decommissioned on 30 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 23 August 1948 as patrol vessel Wakataka (わかたか) (PB-25).[2] On 25 July 1950, she was re-designated as patrol vessel Wakataka (PS-25) and on 1 December 1951 she was redesignated as minesweeper Wakataka (MS-83).[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 April 1956 as special service boat No. 8 (MS-83).[2] On 1 September 1957 she was re-designated as special service boat No. 8 (ASM-58) and on 31 March 1962 as special service miscellaneous ship No. 31 (YAS-31).[2] She was delisted on 31 March 1964.[2]
