A lot of these movies are fantastic. Tampopo, Seven Samurai, Departures; all of these are masterpieces of Japanese film, and I would be too hard-pressed to say one is best of all. Tampopo is in my opinion the best Japanese comedy, Departures is the best Japanese drama and Seven Samurai is the best Japanese period film. I'lll say that much, but they're too different and distinct in their genres to call one the "all time best", in my opinion.
