Hakkaisan Brewery is located in Minami-Uonuma, Niigata, one of the premier and most famous sake brewing regions in all of Japan, and was founded in 1922. The brewery derives its name from Mount Hakkai (八海山), a sacred mountain that is part of the Echigo Sanzan (越後三山) mountain range, the spring of the clear waters of the Haikkaisan river system. Hakkaisan represents local sake tradition in Niigata and produces sake, shochu, plum brandy, beer (Rydeen Beer), whisky and mirin (cooking sake). In 2013, Timothy Sullivan, the founder of Urban Sake, was appointed brand ambassador of Hakkaisan.
