Since it was founded in 1837, Miwa Shuzo, which used to be an Ogaki Domain warrant sake brewery, has been brewing the favorite local sake of Ogaki, which is famous for its plentiful spring water. About 50 years ago, the mayor of Shirakawa village requested to produce unrefined sake like Doburoku, which was served at the Doburoku Festival in the Historic Villages of Shirakawa-go. The resulting product, Shirakawa-go pure rice Nigori-zake (unrefined sake), has become one of Miwa Shuzo’s popular brands, with strong support from domestic and international sake fans.
