Through the story that sake spins
​ Connecting people and regions

Japanese Sake is brewed by reflecting the climate and customs of the land and the skills of the craftsmen. Currently, there are more than 1,000 sake breweries across Japan, and each brews Sake with its own unique character and taste.
​We provide a cultural experience through Sake, and work on domestic sales and exports. In addition, we will operate an online community where fans of sake and Japanese culture from various countries can gather to expand the circle of fans.

​ Through these efforts, we will increase the added value of sake and strive to maintain and develop Sake and Japanese culture.
