This rather expansive prefectural specialty shop sells everything from crabmeat, uni and ikura bento boxes at the front entrance to mochi rice cakes, Iwate beef and dairy products. There's a respectable sake selection as well as craft beers from three different local breweries (Zumona, Baeren, and Iwate Kura). The shop closes at 5pm on the last day of the month.
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.
