If you like cooking and tableware, Kappabashi dori is a must go when visiting Tokyo. This street between Ueno and Asakusa is the home of many shops selling cooking gear and tableware for professionals. Most of the shops sell also to individuals (but it's better to ask before being disappointed). There, you can find pretty much anything from metal sakura shapes to amazing laqueware bowls. Crazy knives and delicates bamboo baskets. With Prunellia we spent a few hours there the other day, and got plenty of new things to cook with!
