Notoro (能登呂) was an oiler of the Imperial Japanese Navy commissioned in 1920, which was rebuilt in 1924 into a seaplane tender and in 1941 back into an oiler. She participated in the First Shanghai Incident in 1932 and the Second Sino-Japanese War since 1937. In the fall of 1941, she was rebuilt back into an oiler. On 9 January and 20 September 1943, she was damaged by US Navy submarines but returned to service after repairs. On 29 June 1944, she was hit by two torpedoes launched by submarine USS Flasher. During repairs in Singapore Notoro was again damaged on 5 November 1944, this time by B-29 bombers. No further repairs were made until the end of the war and she was probably scrapped in 1947.
