Kao, aka Faces by Junji Sakamoto

Sakamoto-san won a Japanese Academy Award for Best Director for this film.
Faces is a dark comedy,
a Japan “road movie”. A honest portrait of different Japanese lives. A fable
of “you are responsible for your own actions”. A dark “coming of age” movie.

Best quote from the movie, slightly paraphrase: Do not die. You have
to go on. When you are hungry, you eat. When you are hungry again.
You eat again. That is the only way to keep going.

Go find it and see it.
