History[edit]

She was laid down on 11 April 1944 as ship number 2078 at the Shimonoseki shipyard of Hayashi Kane Heavy Industries (林兼重工業株式會社 - now known as Hayashi Kanesen Co., Ltd jp:林兼造船).[1][2] She was completed and commissioned on 21 September 1944 and assigned to the Mako Guard District operating out of Takao.[2] She conducted patrol, escort, and minesweeping duties between Kagoshima, Chiringashima, Koniya (jp:古仁屋), and Keelung.[2]

On 28 October 1944, she served as an escort of convoy KATA-916 along with a Type D escort ship (CD-30), a Chidori-class torpedo boat (Manazuru), a No.28-class submarine chaser (CH-49), a W-13-class minesweeper (W-15), 3 auxiliary minesweepers (Himeshima Maru, Shonan Maru No. 16, Toshi Maru No. 7), 3 auxiliary subchasers (Showa Maru, Cha-216, Cha-235), 3 auxiliaries (Kiyo Maru, Kochi Maru, Aikawa Maru), and an auxiliary netlayer (Kiri Maru No. 1 Go) for 13 transport/cargo ships (Tensho Maru, Amakusa Maru, Shinton Maru, Sanka Maru, Sanjin Maru, Hayama Maru, Torai Maru, Taikyu Maru, Sakishima Maru, Bansei Maru, Choki Maru, Kishin Maru, Kankyo Maru).[3] The convoy moved cautiously from island to island departing from Naha then the Kerama Islands then Miyako-jima and then Iromote-Jima, Yaeyama Islands before finally arriving at Keelung on 1 November 1945.[3] On 5 January 1945, she left Keelung escorting convoy Kita-9 consisting of 6 transports (Kankyo Maru, Torai Maru, Taiken Maru, Kishen Maru, Yaei Maru No. 10, Banshu Maru No. 31) along with 2 auxiliary netlayers (Choki Maru, Kiri Maru No. 1 Go), and 5 auxiliary subchasers (Showa Maru, Cha-216, Kochi Maru, Kyo Maru, Ayugawa Maru) headed to Kaohsiung.[3][2] On 6 November 1944, the convoy arrived at Kaohsiung.[3]

On 15 March 1945, she was assigned to the 2nd China Expeditionary Fleet.[2] She survived the war.[2] On 18 September 1945, she flooded and sank after being caught in a typhoon northeast of Sasebo.[2]
