5. Momotaro: Umi No Shinpei (Momotaro’s Divine Sea Warriors) 1945
When Momotaro’s army arrives at one island, they warn the animals about the Western colonists and inform the animals of the army’s mission to free them from their oppressors. Thereafter, Momotaro leads his army and the local animals on an attack against a British military outpost on the island.
The cartoon flopped upon release because most of the intended viewers (the children) had been evacuated from the Japanese cities due to heavy Allied bombings. The few still around worked in factories and were unable to watch the cartoon.
The cartoon was lost after the war until a copy was found in 1983. It was released on home video and has now been rereleased on Blu-ray as Momotaro, Sacred Sailors.
