Kikaku Sembei

"A longstanding senbei rice cracker shop located a one-minute walk from Exit 1 of Monzen-Nakacho Station on the Tokyo Metro Tozai Line. From old school hard-baked senbei such as the Nihon Ichi Katai Genkotsu (""Japan's Hardest Rice Cracker"") and Shinjitsu no Shoyu Senbei (""The True Soy Sauce Senbei"") to snackable arare cracker bits, the shop's products are loved not only by locals but also fans across the country. In all, the shop offers over 100 varieties of rice snacks - in addition to standard katayaki hard rice crackers, you'll also find Okaki Macarons, a novel new, macaron-like rice cracker dessert; light and crispy arare snack bit mixes; and more. The shop's products also make great gifts and souvenirs. The popular shop has also been featured on television."
