OSE was built in Hamburg, Germany for the Dutch firm La Corona of the Hague. She was completed in 1935 and named GENOTA. Later, she saw service as a tanker for Royal Dutch Shell. In 1942, GENOTA was captured in the Indian Ocean by Japanese armed merchant cruisers AIKOKU and HOKOKU MARUs. Later that year, she was converted to a fleet oiler, renamed OSE and commissioned in the IJN. In March 1944, OSE was bombed and sunk at Palau by Task Force 58 carrier-based aircraft.
