"If this drop of water spreads all over the world..."
That phrase always pops into my mind when I drink sake. Sake is a complex drink that begins with rice and clean water and is helped along by microorganisms known as koji. It has an ancient origin with roots connecting it directly to the initial cultivation of rice. Brewing techniques and beautiful surroundings have been passed down from this era and into today, these practices being protected and refined for over 1,000 years.
There are more than 1,000 Sake breweries in Japan, and the taste of the Sake produced is highly dependant on the local climate, history, and brewing policy, all of which determines a brewery's distict flavor. Japan itself, along with each individual prefecture, is tightly confined in each drop.
We want many people, both domestic and foreign, to visit Sake breweries in various regions and experience the ancient breath of history. We aim to help spread the charm of each region in Japan, including the hometowns where each of us were born and raised.
