The foot of Yatsugatake and Mt. Tateshina, which is located, is one of Japan's leading agar production areas.
This climate, which produces the finest agar that can not be done without severe cold air, and the clear cold, is a suitable place for sake brewing.
The brewing water is clear underwater, which is the source of Mt. Tateshina, which looks up to the east.
This Yui, which is called a woman, is a soft water that is neither sweet nor dry, and has a very soft mouthfeel.
