Otokoyama Sake Brewery Museum (Asahikawa City) exhibits materials and information related to Japanese sake. Visitors can learn about 'Otokoyama' in particular, which was first created in the 17th century. In the brewing season, there is a tour around the factory. A movie introducing the process of brewing is available anytime. At a Japanese garden in front of the building, there is a spring of natural, pure water which is used for the sake. You are allowed to have a drink from the spring throughout the year, but large amounts of water cannot be taken away. This water is called Long Health Life Water.
