Iwate prefecture’s antenna shop is located across the street from the Kabukiza theater. This was a great place to get your bento lunch if attending a kabuki show. The theater is closed at the moment as a new theater is being built, scheduled to reopen in the pring of 2013. However, the bentos have not disappeared and are a popular item as the bentos are brought in daily from Iwate. The wagyu bento is very popular. Also be sure to check out the seafood based bentos.
Seafood products are a highlight of the shop. In particular, packaged goods from Nakamuraya 中村家, from Kamaishi city in Iwate. The most popular item currently at the shop is above, awabi and ikura. This with a hot bowl of rice is a meal fit for a king.
A variety of noodles are also available. My personal favorite is the Morioka reimen, cold noodles in a refreshing broth. The noodles are made from potato starch and flour and as a result are very chewy. If you are craving a bowl of reimen there is a branch of the Iwate restaurant chain, Pyon Pyon Sha, in Ginza:

The other noodles from Morioka that are famous are soba and jya jya men (udon noodles with a miso meat sauce and vegetables). You’ll also find these at the Iwate antenna shop.
