Yeah, loved Zatoichi, especially the closing dance number. Crazy. Made me want to see more movies by Takeshi Kitano (aka "Beat Takeshi").

I've only managed to catch one or two others. I can recommend Kikujirô no natsu, a really gentle and offbeat comedy/road movie about a washed-up gangster who gets roped into taking a young boy up north to see his mother. It's sad, strange, slow-moving, hilarious, highly unlikely, and totally Takeshi. His sense of humor and directorial choices are utter unique.
