This stylish, contemporary counter bar offers a selection of sakes from 17 different breweries located throughout Japan's Toyama prefecture, across the alps from Tokyo and bordering the Japan Sea. A set of three 30mL cups costs a bargain ¥700 (90mL cups from ¥700 each). English tasting notes are available.
It's part of the Nihonbashi Toyama-kan (日本橋とやま館), which promotes goods from the prefecture. Pick up a bottle of anything you like at the attached shop.
