Ah Japanese films, I used to watch a lot of those. That's how I got interested in Japanese.
I think I have over 500 in my home country, thanks to the golden days of edonkey networks. I wonder if people still use them.
I think the best website about asian cinema is http://www.midnighteye.com
They have good reviews, and not only about extremely violent flicks. They even have interviews with directors.
I think the Snowblood Apple site looks like a myspace page and is interesting to people who are solely into the gore extreme violent stuff (like me when I was 16). To each his own.
A few random favorites in English (at the time of watching I didn't know any Japanese), all set in contemporary Japan.
The Eel (unagi, original story)
Drunken Angel (Yoidore Tenchi, by Kurosawa, great acting)
Survive Style 5+ (very funny!)
Happyness of the Katakuris
Go-con, japanese love culture (actually not so interesting, but it explains about go-con, and i think it's good for learning Japanese, because the guys repeat their stories to each girl)
Bounce, Kogalls (Kogalls = Call girls, surprizingly good)
Tampopo (makes you love ramen if you didn't already)
Blue Spring (cool music and images)
Ping Pong
Go
Monday
The Taste of Tea (cha no aji, this one is the king of Japanese sunday afternoon movies, funny relaxed and beautifull)
Picnic (by Shunji Iway)
All about Lily Chou Chou (beautifull music and images, one of the first fully digitally shot mainstream movies in Japan)
Audition (this one is gory, but not your average horror movie)
As you will notice there isn't anything from the last couple of years. After I moved to Japan, I pretty much stopped watching them!
