He made a 10hr film criticizing Japan's role in WWII (based on the autobiography of Junpei Gomikawa ) titled The Human Condition 「人間の條件」, burning indictments of samurai code Harakiri 「切腹」 and Samurai Rebellion 「上意討ち 拝領妻始末」, and a collection of folk ghost stories called Kwaidan 「階段」 to name a few.
Basically if you like Kurosawa films but wish they were more critical of power, check this guy out
Dude also looks like a Japanese DeVito
I'll update this post with DLs for some of his films in 1080p once they're done uploading
Different director but I think the film Humanity and Paper Balloons (1937) directed by Sadao Yamanaka and focuses around these people living in a slum in Edo.
I watched for a film class about Sumurai films and it was the first one the professor showed, not what I expected but I really liked it.
Interesting thing we talked about is that the film was made before Japan kicked off its invasion into China and there is a feeling of dread present in the film, even the director was drafted and died in 1938.
