My favorite is the first one. The first half hour is so interesting that I fall in love with the quietness of the movie, the beautiful landscape and the way the movie is made. Simple, nothing outrageous, with quiet soundtracks, little dialogues and lots of silent sweet gestures. Misaki Ito as the painter and Wilson Chen, a Chinese cartoonist living in Tokyo, act exceptionally well.
The second one is the least interesting but the one that gets me laughing the most. A reckless Japanese man helps a woman get over her broken heart, but he doesn't really know how to. They go through a painful conversation - painful because they cannot understand what each other is speaking.
The last one is teary and beautiful. The daughter of the shopkeeper who rents the house to a Japanese teacher falls in love with him. But her love seems unrequited, and he does not even know she loves him until he comes back a year later. Out of every Japanese movie ever made, I think this is the best one. I love it!
