You might not need a bamboo tub to hold 25 pounds of sushi rice, but there is plenty for the home kitchen at the Japanese Culinary Center, a retail and wholesale showroom for a major importer. They have elegant knives, porcelain dishes that start at $1.50 and simple slicers for around $35. There’s hand-crafted plastic sushi ($8.30 to $38.90 a piece), as well as real edibles, like organic tamari, $26.50 for two quarts, and earthy purple sweet potato vinegar ($33.20 for 16.6 ounces), which also comes honey-sweetened ($39.70 or $9.40 for four ounces) and is good in iced tea.
