Kisoji is the flagship brand of Yukawa Shuzoten, a brewery with over 370 years of history situated at 933 meters elevation in Kisomura, Kiso Valley, Nagano Prefecture, among the highest-altitude sake breweries in Japan. The brewery describes itself as Japan's closest sake brewery to the stars, and the extreme cold of the mountain winters suppresses bacteria and enables slow, precise fermentation. Multiple IWC Gold medals, including for the Kisoji Junmai Sankeinishiki, mark the brand's standing as a benchmark for Kiso Valley sake.
