History

Magane Maru was laid down on 14 December 1939 at the shipyard of Harima Zosensho at the behest of shipping company, Nihon Kaiun.[3][4] She was launched on 15 June 1940 and completed 5 August 1940.[4] On 5 September 1941, she was requisitioned by the Imperial Japanese Navy and converted to an auxiliary minelayer/gunboat under Reserve Lieutenant Maniwa Kenji (間庭建爾).[4] Armaments mounted were 1 x 8 cm/40 3rd Year Type naval gun, 1 twin Type 93 machinegun (jp) (based on the Hotchkiss M1929 machine gun), 1 Type 3 heavy machine gun, and 120 mines.[3] In December 1941, she was assigned to Gunboat Division 10 of the 5th Fleet under Lieutenant Commandeer Sasaki Heiji (佐々木丙二)(jp).[4] On 10 April 1942, she was detached from Gunboat Division 10[4] and attached to the Adak-Attu invasion force under Rear Admiral Sentarō Ōmori during the Aleutian Islands campaign.[5][6] On 25 September 1942, she was reassigned to the Yokosuka Naval District.[4] On 25 May 1943, Sasaki was replaced by Reserve Lieutenant Yamazaki Kiyoichi (山嵜來代一).[4] On 18 September 1943, Yamazaki was replaced by Reserve Lieutenant Shigematsu Yoshioka (吉岡茂松).[4]

On 24 January 1944, she was attacked and sunk by the American submarine USS Snook about 175 miles northwest of Chichi Jima (29°49′N 140°08′E)[4] (Japanese sources indicate 30°06′N 141°19′E).[3] She was struck from the Navy List on 10 March 1944.[4]
