Oishi Sake Brewery Co., Ltd. lies 15.5 miles (25 kilometers) west of Kyoto City center. For approximately 150 years, a long-established family dating back to the year 1700 has been producing sake. Sugio Oishi is the eighth-generation sake brewer and employs the traditional kimoto brewing style.

The Tanba region where the brewery is located is home to a group of sake-making artisans, the Tanba Brewers Guild (Tanba Toji) whose origin goes back to the Edo Period in the 18th century. Master brewers affiliated with this association have continued to hone their skills by working in sake breweries throughout Japan.
