Rich in trace elements — gentle on the skin.
Soft water — natural, classic buoyancy.
Beer Spark Shimotsuma in Shimotsuma City, Ibaraki Prefecture, is a uniquely conceived third-sector facility that combines thermal spring bathing with an on-site craft beer brewery—an integration that reflects the contemporary Japanese enthusiasm for artisanal brewing within a wellness facility context, creating a destination where the pleasures of natural mineral bathing and freshly brewed craft beer form a complementary evening itinerary. Operated by a public-private partnership with investment from both Ibaraki Prefecture and Shimotsuma City, the facility draws approximately 500,000 visitors annually, establishing itself as one of the region's most successful examples of thermal spring tourism anchored by distinctive culinary production. Opening in May 1999, Beer Spark Shimotsuma has become a template for the creative pairing of onsen culture with Japanese craft food and beverage traditions.
