The Yellow Handkerchief

You could describe it as a gritty, "thinking man's Tora-san" (in fact it shares a script-writer and some of the same cast as the early Tora-san films). Funny in many places but not a comedy; more like a slice-of-reality, on-the-road film in which three strangers are thrown together and romantic love triumphs in the end. Not an art film by any means, but great in its own way.
