An utterly bizarre Japanese cartoon from 1934, found courtesy of the excellent Cartoon Brew website. A whole lot more interesting information on this can be found in the comments there.

Here is part of a comment there by “EricW”:

This appears to be Komatsuzawa Hajime’s “Toybox Series #3: Picture Book 1936″ (a.k.a. Momotaro vs Mickey Mouse). I found this description at http://www.kinema.uwaterloo.ca/white962.htm: “One very popular cartoon character was Momotaro, the “Peach boy,” who appeared in a number of cartoons designed not just for domestic consumption within Japan, but for propaganda use in occupied countries as well. For example, Picture Book 1936 (Momotaro vs. Mickey Mouse) presented fanged Mickey Mouse look-alikes riding giant bats, attacking peaceful Pacific islanders (represented by cats and dolls, for some reason); the hero Momotaro jumps out of a picture book, repels the American mice, and cherry trees blossom throughout the island as the grateful natives sing “Tokyo Chorus.”
