The ship was laid down as hull number 364[1] on 12 July 1918 at the Tsurumi shipyard of Asano Shipbuilding Company[3][2] for the benefit of the Kokusai Kisan Kaisha (玉井商船株式會社).[5] She was the fourth ship of the Yoshida Maru No. 1 class of 25 standard cargo ships (referred to as Type B at the time) built by Asano Shipyard (one was built at the Uraga Dock Company) between 1918 and 1919.[6] She was launched on 5 February 1919, completed on 19 March 1919, and given the name Buyo Maru (武洋丸)[5][3] with the identification number 24999.[1] On 12 July 1932, she was sold to Tamai Shosen K.K. of Kobe and registered in Hashidate.[2][5]

On 16 November 1941, she was requisitioned by the Imperial Japanese Army.[3]

On 2 January 1943, she departed Singapore en route to Ambon[3] as part of a convoy including fellow Imperial Japanese Army transports Pacific Maru and the Fukurei Maru No. 2. Buyo Maru was carrying 1,126 soldiers and 269 Indian prisoners of war (POWs) from the 16th Punjab Regiment. On 26 January 1943, the convoy was spotted by the US submarine Wahoo and Buyo Maru was torpedoed and sunk at 02°00′N 139°33′E.[3][7][8] 195 Indian POWs and 87 Japanese died.[9]
