Momotarou: Umi no Shinpei

Like the prior film, the movie features the "Peach Boy" character of Japanese folklore. The film is about the surprise maneuver on Sulawesi island, depicting parachute troops' actions. The whole movie also depicts how Japan "liberates Asia", as proclaimed by the Government at the time.
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.
