For over 150 years since 1866 (Keio 2), when the founder, Jirohei Nagai, began brewing sake using the underground water of the Yahagi River, the brewery has prioritized quality, crafting sake with great care to be recognized as "delicious" and "umai." With the integrity and deep sense of community characteristic of the people of Mikawa, the brewery has upheld trust as its core value. The sake, brewed with time-honored techniques and a strong commitment to craftsmanship, reflects the rich natural environment of Mikawa, resulting in a full-bodied, flavorful (noujun-umakuchi) masterpiece.
