Somewhere Only We Know -- Chinese but it is my favorite asian movie so far. Very very beautiful, imo.
Teacher's Diary -- it's Thai, but I found it very beautiful and enjoyable. It's not in a very high quality on this site though, so I'd recommend you to watch it on kissasian.com.
The Beauty Inside -- Korean; it is one of my favorite movies ever, it is super good.
Our Times -- it's Taiwanese, but again, very enjoyable and fun.
The Witness -- Chinese remake of the Korean movie Blind, I haven't seen the original but this was pretty intense, and I quite liked it.
