If you loved The Adventure of Denchu-Kozo, try Tetsuo: The Iron Man
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Shinya Tsukamoto, and they both carry the body horror, surreal mood tags, and they sit in Horror / Science Fiction territory. If that's the register that drew you to The Adventure of Denchu-Kozo, the second film will land in a comparable space — through a different lens.

What Tetsuo: The Iron Man is
Dawn on a rain-slicked Tokyo backstreet. A man sprays molten scrap into open sores, melts into flickering neon. Two lovers flee his collapsing body under a salvage crane. The iron begins inside him, spreads like rust through veins.
