The Mukai Shuzo was founded in 1754. Mukai Kuniko, the toji of Mukai Shuzo is one of the first women toji in Japan. She is constantly experimenting with new types of sake, most of which are made in miniscule amounts. Ine Mankai, the product of one of these experiments, is using a unique variety of red rice that prevents ugly colour changes over time. The brewery itself is right on the Japan sea, in a picturesque village, known throughout Japan for its unique boat garages (funaya), located right under the houses that stick out over the water.
