“Basically, we try to make an honest sake,” says Yoshihiko Nishioka, the brewery’s director. “For us, that’s a sake that is gracious and accommodating. We don’t go in much for sakes with assertive individual characteristics. In a word, we make the kind of sake we like to drink ourselves, and that the people from around here can be proud of.”
There are 27 sake breweries in Gunma, most of them quite small with the toji-owners working side by side with the brewery workers. There are few pretensions, and the brewers freely exchange information with one another. In many breweries, Seitoku included, the toji do not belong to traditional guilds. They make Gunma sake as they see it, and the brewery workers are all from Gunma too.
Nishioka-san studied under Dr. Chieko Kumagaya, regarded as the grand doyen of ginjo sake-brewing in Japan. Brewers from all over the country would come for advice on how to improve their sake, and as she pointed out faults, praised virtues and proffered advice her protege gained invaluable insights on what it takes to brew award-winning sake.
When the time came to return to his brewery in Gunma he was determined to follow her teachings. “Great advances have been made in our scientific understanding of how sake is made. Knowledge is our foundation and we take pride in that. But we never forget Prince Shotoku’s precept and our company’s guiding motto.”
