Juzo Itami, director of "Tampopo," is back in the food business again. This time he hits the big supermarkets and their nefarious ways. They buy cheap and sell high, they repackage yesterday's fish and refry last week's croquettes. Worst of all, they willfully market Australian beef dressed up as Japan's precious steak. But they meet their match in Nobuko Miyamoto, who steps in and cleans things up. Just as she outwitted tax offenders, big business scammers and evil gangsters in previous Itami films, so she now does her level best to make the super market safe for the local housewife.
