Journey on the Nakasendo: From Historic Teahouse to Modern Sake Innovator
Originally the owners of a “dango” (sweet dumpling) and tea shop in the historic post town of Otajuku along the Nakasendo route, the Watanabe family transitioned to the art of brewing in 1893. Today, Miyozakura Brewing Company operates as a “small but mighty” team of five, led by sixth-generation president and brewer Hiroe Watanabe, who took the helm at just 29 years old. The brewery carefully maintains two distinct identities: the traditional “Miyozakura” brand, which honors regional roots;, and the limited-production “Tsushimaya” brand, a platform for bold experimentation and premium craftsmanship.
Our opportune meeting with President Watanabe
Our journey with this brewery began when our team members in Japan attended an event hosted by the Gifu Prefecture Sake Brewers Association, featuring about 30 local producers. While navigating the vibrant gathering, we were immediately struck by the clarity and depth of the Tsushimaya line. We had the opportunity to speak directly with President Hiroe Watanabe and learned that while their flagship brand was already available in the U.S., these more exclusive “Tsushimaya” labels remained largely undiscovered abroad. This inspiring encounter left a lasting impression, as we realized we had found a hidden gem of Gifu that we hoped to one day share with our community of sake enthusiasts in the U.S.
Roots in the Otajuku post town
The brewery sits in a corner of Minokamo, Gifu prefecture, that feels like a living museum preserving the atmosphere of the Edo period (1603-1868) post town of Otajuku. Otajuku was once a vital stop for travelers on the Nakasendo — a historic highway that connects Kyoto with present-day Tokyo — famous for the Ota no Watashi river crossing. The brewery’s original name, Tsushimaya, was actually the name of the family’s ancestral dumpling teahouse. By reviving this name for their premium brand in 2012, they have signaled a return to their original mission of creating a place of “healing and relaxation” for people to gather and enjoy life.
Meticulous craftsmanship by the sixth generation
Hiroe Watanabe is a hands-on brewer who lives and breathes the craft, often staying in the brewery day and night during the winter months. He remains committed to traditional, labor-intensive methods, such as using a “koshiki” (a traditional large steamer) to steam the rice and producing 100% of their koji rice by hand. He follows the Tajima-style of brewing, a method that emphasizes a slow, 47-hour koji-making process to ensure the rice is perfectly transformed for fermentation. This dedication is evident in their production scale; they have focused on smaller batches of approximately 400 to 500 “koku” (roughly 19,000 to 24,000 gallons) to ensure that every drop meets their exacting standards for an easy-drinking yet memorable flavor.
Why this matters
We selected Miyozakura Brewing Company because they represent a perfect balance of historic reverence and youthful energy. Their refusal to cut corners — investing incredible time and labor into every step of the brewing process — mirrors our own dedication to quality. The result is a collection of sake defined by a delicate, fruity and elegant character that is both sophisticated and approachable. When you open a bottle, you aren’t just tasting fermented rice; you are experiencing the heritage of a Nakasendo post town and the heart of a brewer who is thoughtfully redefining Gifu’s sake for the modern world.
