Momotaro: Sacred Sailors (桃太郎 海の神兵, Momotarō: Umi no Shinpei)[2] is the first Japanese feature-length animated film.

[3] It was directed by Mitsuyo Seo, who was ordered to make a propaganda film for World War II by the Japanese Naval Ministry.

While Santa frolics in the field chasing the cap in the wind, the monkey observes the dandelions spreading their seeds and is mesmerized by its beauty.

The Japanese forces are seen clearing a forest and constructing an airbase on a Pacific island with the help of the jungle animals who sing as they work.

A plane lands at the airstrip and from inside emerges Momotaro, depicted as a General, together with the bear, monkey, dog, and pheasant, who by this point have become high-ranking officials.

Thereafter, a narration of the story of how the island of Celebes was acquired by the Dutch East India Company follows and it is revealed that the Japanese are attempting to invade it.

A brief epilogue shows Santa and other children playing paratrooper and jumping onto a chalk outline of continental America.

Inspired by this, Seo tried to give dreams to children, as well as to instill the hope for peace, just as he did in the film's predecessor, Momotaro's Sea Eagles.
