Sweet potato shochu_Kokubu Shuzo/Kuroishidake

In 1986, six companies agreed to the unification of manufacturing licenses and established the Kokubu Shuzo Cooperative in Kokubu City, Kagoshima Prefecture (now Kokubu, Kirishima City), built a brewery, and began producing sweet potato shochu. In 1997, they became the first in the industry to produce sweet potato shochu made from 100% sweet potatoes without using rice koji. In 2000, they began producing shochu using yellow koji and aged koji, and have continued to make tireless efforts to improve quality, including working to revive the Tsurunashi Genji sweet potato, which was cultivated during the Taisho era.
