I saw a police movie made in Japan ca 1950 about a detective on a murder case. It was an unfiltered slice of Japanese life from that time that you just don’t see in the mainstream. I was a little surprised at how Western everyone dressed and acted. It was like watching an American crime flick from the same era, but with Japanese actors and English subtitles.
Wish I could remember the name.
I’m sure there are a lot of Japanese police movies, but these two are more well known in America because they were directed by Akira Kurosawa - “Stray Dog” and “High and Low”. Possibly one of those?
