Maruyama Onsen sits in Sapporo, Hokkaido, drawing sodium-chloride water at 41°C. Guests can use an indoor bath, an outdoor rotenburo and a sauna, right within the island's largest city.
Insider tip — Maruyama Onsen is located in the Maruyama district of western Sapporo, adjacent to the forested Maruyama Park and Hokkaido Shrine. Urban Sapporo draws saline sodium-chloride waters from sedimentary basins beneath the Ishikari Plain, and neighborhood onsen facilities like this one are integral to Sapporo's residential culture. The baths offer a restorative experience after hiking Maruyama Hill or visiting the nearby zoo and botanical garden. In winter, Sapporo's famous powdery snow season makes a warming saline soak a perfect cap to a day of skiing or exploring the Susukino festival district.
