Momotarō: Umi no Shinpei (Momotaro's Divine Sea Warriors) - Mitsuyo Seo [1945]

First feature length animated film from Japan. Released in March 1945. Directed by Mitsuyo Seo.

Momotarō: Umi no Shinpei (桃太郎 海の神兵, lit. Momotarou: God Warriors of the Sea or Momotaro, Sacred Sailors) is the first Japanese feature-lengthanimated film. It was directed by Mitsuyo Seo, who was ordered to make apropaganda film for World War II by the Japanese Naval Ministry. Shochiku Moving Picture Laboratory shot the 74-minute film in 1944 and screened it on April 12, 1945. It is a sequel to Momotarō no Umiwashi, a 37-minute film released in 1943 by the same director. It is black and white.^[4]

In English, the film is known as Momotaro's Divine Sea Warriors.

After completing naval training, a bear cub, a monkey, a pheasant, and a puppy say goodbye to their families. While they are preoccupied, the monkey's younger brother falls into a river while chasing the monkey's cap and is carried towards a waterfall. The dog and the monkey work together to save the child just before he is swept downstream. A time skip occurs and Japanese forces are seen clearing a forest and constructing an air base in a Pacific island with the help of the jungle animals. A plane lands in the airstrip and from inside emerges Momotaro, depicted as a General, together with the bear, monkey, dog and pheasant, who by this point have became high-ranking officials. The subsequent scenes show the jungle animals being taught the alphabet via singing, washing clothes, given military training, and loading weapons in warplanes. The animal residents of the island are shown as simple primitives who are star struck by the glamorous and advanced Japanese animals.

A narration of the story of how the island of Celebes was acquired by the Dutch East Indian Company follows and it is revealed that the Japanese are attempting to invade it. The monkey, dog and bear cub become parachute jumpers while the pheasant becomes a pilot. The paratroopers ambush a halftrack and hastily invade a British fort, causing the unprepared British soldiers to panic and flee. Momotaro, the monkey and the puppy are then shown negotiating with three British officials and after a brief argument, the British agree to surrender Celebes and the surrounding islands to Japanese rule in exchange for freedom. A brief epilogue shows children playing at parachuting onto continental America outlined on the ground. Plainly the United States is to be the target of their generation.

There are some musical scenes. Of note is The Song of AIUEO (アイウエオの歌 AIUEO no Uta), a scene where Japanese soldiers teach local animals how to speak.

The Naval Ministry previously showed Seo Fantasia, a 1940 Disney film. 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 prequel movie, Momotaro's Sea Eagles.

For a long time, the film was presumed to have been confiscated and burnt by the American occupation. However, a negative copy of the film was found in Shochiku's Ofuna warehouse in 1983 and was re-released in 1984. A reproduced movie was later screened and the VHS package is now available in Japan.

The Song of AIUEO (アイウエオの歌 AIUEO no Uta) is famous for being given a homage in the series Kimba the White Lion (ジャングル大帝 Janguru Taitei) by Osamu Tezuka. Tezuka had seen the film in April 1945. He later said that he was moved to tears by the movie's hints of dreams and hopes, hidden under the appearance of war propaganda.
