The only sake brewery in Komoro City, Nagano Prefecture, Otsuka Shuzo crafts its sake using water known to be the hardest in the region. This unique water, combined with locally grown Shinshu sake rice, creates Asamadake — a sake that is rich in flavor yet remarkably crisp and clear.

We were also drawn to the passion for sake shared by Kiyomi Otsuka, the brewery’s eighth-generation brewmaster, and her husband Hironori Otsuka, the director of the film "The Story Beyond a Cup of Sake". Inspired by their dedication, we decided to begin working with them.
