Yonezawa Shuzo Co., Ltd.

Visit and take a look at the equipment for “sakabune-shibori,” a method to make sake that is rarely practiced today.
It involves carefully lining up in a sakabune (sake tank) the bags used to strain and then slowly straining sake from them. (From early May to mid-October; reservation required.)
You can also enjoy sake-tasting at the shop here.
