She was laid down by Nippon Kokan K.K. (日本鋼管株式會社) at their Tsurumi, Yokohama shipyard on 15 July 1944, launched on 29 September 1944, and completed and commissioned on 2 November 1944. She was attached to the Yokosuka Defense Force, Yokosuka Naval District under Lieutenant Commander Fukuji Chiba. During the war CD-47 was mostly busy on escort duties mainly to the Ogasawara Islands and the Kurile Islands.

Convoy-Chi
On 26 May 1945, she departed Paramushiro for Otaru, Hokkaido in convoy-Chi consisting of cargo/transport ships Kuretake Maru, Kasugasan Maru, Tenryo Maru, and supply ship  Shirasaki, with Shimushu-class escort ships JAPANESE ESCORT Shimushu and JAPANESE ESCORT Hachijo, fellow Type C escort ship CD-205, and Type D escort ship CD-112. Hachijo was lost in the fog around 50°N, 146°W and CD-205 left the convoy to search for her. On 29 May 1945 at 2055, the U.S. submarine USS Sterlet (SS-392) fired two spreads of three torpedoes hitting two of the freighters. Tenryo Maru quickly sank at 46.76667°N, 144.26667°W killing 773 out of 947 men of the 23rd Air Defense Battalion, 26 gunners, and 83 sailors. Sterlet also severely damaged Kuretake Maru which sank the following day with a death toll of 272 soldiers and six sailors.

On 15 July 1945, off Otaru, she was damaged along with CD-55 and Etorofu-class escort ship Kasado by U.S. Navy planes from Task Force 38.

On 14 August 1945, while escorting a freighter, she was torpedoed and sunk by the submarine USS Torsk (SS-423) off Tottori in the Sea of Japan (at 35.68333°N, 134.63333°W). On 15 November 1945, she was struck from the Navy List.
