This rather large antenna shop sells a good variety of local food products from Kagoshima Prefecture, including freshly made satsuma-age (deep-fried vegetable- and fishcakes). Ready-made kakuni and tonkotsu stews made with local Berkshire pork can be found in the freezer cabinet alongside charcoal-grilled chicken and frozen fish.
There's also an impressive selection of shochu, and a bit of fresh produce (mostly yams). Up on the second floor is a Kagoshima restaurant, and on the third floor there's a local craft shop.
This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
