Name Origin
Name Origin
The name comes from Mount Sanko in northwestern Okayama Prefecture.
Sanko Masamune stands in a valley where Kamishiro River, the source of the Takahashi River, one of Okayama's three major rivers, flows behind it. The mountain in front is said to be home to the Sanko bird, whose call is said to resemble the Japanese words for “moon, sun, and stars”.
Nearby is the beautiful Koi no Kubo wetland, known as the Oze of the West, with seasonal plants.
The Yamada Nishiki rice used at our brewery is also grown just downstream from here.
Surrounded by highland mountains, with clear air, brewing water, and high-quality rice, Sanko Masamune is located in an area blessed with ideal conditions for sake brewing.
