Momotaro in the Sky

Overview

Momotarou, a protagonist in a traditional Japanese story, appears in a contemporary story and sets off to the Antarctic instead of Onigashima Island to defeat a rogue eagle. Released at the time of the Manchurian Incident in 1931 and the Shanghai Incident in 1932, this film quickly gained popularity and Umi no Momotarou, its sequel, was produced shortly afterward.
