At the Kimura Shoten store, which is the sole producer of the unique liquor containers called "Ika Tokkuri," the skins of cuttlefish caught off the Sanriku Coast are formed by hand in the shape of tokkuri (sake bottles) and then repeatedly dried in the sun.
When you pour warm sake into an Ika Tokkuri, the taste of squid melts into the sake, giving it a mild taste.
After you down the sake, you can even eat the squid container itself.
Ika Tokkuri are sold at tourist spots in Iwate Prefecture and through the Internet. They are priced at around 1,000 yen ($9) each.
