Momotarō no Umiwashi (桃太郎の海鷲, literally Momotarō's Sea Eagles) is an animated Japanese propaganda film produced in 1942 by Geijutsu Eigasha and released March 25, 1943.
Running at 37 minutes, it was close to being feature-length, but it was not the first animated feature film in Asia; that honor goes to China's 1941 Princess Iron Fan, which was 73 minutes long.
