Anime Like Momotaro under the Sea
Nobody talks about this one. A 1930s propaganda film that trades the sky for the ocean, swapping mechanical spectacle for the genuine strangeness of deep water, Momotaro piloting a submarine to fight a giant shark is exactly as surreal as it sounds, and the film leans into that weirdness instead of fighting it. The animation captures something most early anime never attempts: the alien weight and pressure of being underwater, where even a folk hero looks small. Watch it for the historical curiosity. Stay because it moves like nothing else from that era.
SYNOPSIS
A young warrior born from a giant peach finds himself aboard a mechanical submarine, descending into the ocean's darkest depths. His mission is clear: confront the massive shark terrorizing the waters below and restore peace to the realm beneath the waves. What begins as a straightforward adventure becomes something stranger the further down he travels. The submarine's cramped corridors give way to bioluminescent caverns and impossible underwater cities. Momotaro discovers that his legendary strength means little in this alien environment where pressure, darkness, and ancient creatures test him in ways no surface battle ever could. The shark itself proves far more formidable than expected, forcing Momotaro to abandon traditional heroism and learn to fight on the ocean's terms. His companions and ingenuity become as crucial as his courage. This underwater sequel transforms a familiar folk tale into a claustrophobic science fiction spectacle that asks whether a hero's greatest victory might come not from triumph, but from understanding a world completely foreign to his own.
