Message from CEO

Representative introduction


​ Representative Director Nanako Miyauchi

Born in Asahi City, Chiba Prefecture. JSA Sake Diploma, WSET SAKE Level3, SSI International Sake Instructor. At the University of Tokyo and the Graduate School of the University of Tokyo, researched the environmental tolerance mechanism of rice. She became addicted to sake when she was a university student, and in 2018 she became the representative of Miss Sake Ibaraki. After working at Goldman Sachs, established Iris Co., Ltd. in July 2022 to contribute to increasing consumption of Japanese alcoholic beverages through regional tours.

"If this drop of water spreads all over the world..."

I always feel that way when I drink sake. Sake is made from rice and clean water with the help of microorganisms. It has an ancient origin, and it is said that the history of sake began with the introduction of rice farming. Brewing techniques and beautiful surroundings have been passed down, protected and refined for over 1,000 years.

There are more than 1,000 sake breweries in Japan, and the taste of the sake produced is completely different depending on the local climate, history, and brewing policy. Japan is tightly confined in that drop.

We want many people, both domestic and foreign, to visit sake breweries in various regions and feel the breath of history and climate. We would like to help spread the charm of various regions, including the hometown where we were born and raised.
