Founded in 1902 (Meiji 35), Watanabe Shuzojo, located in Hayashi Town, Ogaki City, Gifu Prefecture, has been committed to making delicious sake for over 100 years, continuing to be loved by the local community. Ogaki City, where Watanabe Shuzojo is located, is known as the "City of Water" due to its abundant spring water and clear streams. The brewery uses this natural spring water, along with "Koga no Mori Water," which comes from the high-quality spring water of Mount Koga in the Oku Nagara River area. With a focus on the quality of water, Watanabe Shuzojo continues to innovate in its sake production.
