If you like Tampopo I recommend everything else by Jūzō Itami. Especially "Minbo no onna", a comedy about the Yakuza (Japanese mafia), one of the most brilliant comedies I know.
I thought it was a serious introduction for foreigners for the first few minutes until I settled on it being sarcasm, which is heavily punctuated towards the end.
Made by the inimitable comedy duo "Rahmens" - some of their other work is subtitled and on youtube, all highly recommended! (though I couldn't attest to how well the humor translates..)

Even if you don't like Sushi the documentary itself, the style, the characters, the subjects are just every well done.
