Recommendations for movies set in Japan?

[Morsoth]

Hi guys, I'm very into Anime and Manga at the moment, and also into Japanese culture, so I wanted to ask you for recommendations (any genres) for live action movies available on Blu-ray (Region A) set in modern Japan. I looked at some lists on the web, but I prefer to ask here instead.

I have some, but I clearly need to expand my horizons. For reference, here is what I currently own (or have on order) :

Japanese Movies



American Movies



Thanks in advance!
