Mikata Onsen is a relaxing hot spring destination in the Wakasa-cho area of Fukui Prefecture, set within the scenic Mikata-Goko (Five Lakes of Mikata) region, a designated Ramsar Wetland of international importance. The siliceous waters here offer restorative mineral bathing with views of the surrounding freshwater and brackish lakes, home to diverse waterfowl and traditional fishing communities. This onsen provides an unusual combination of natural wetland ecology and thermal wellness, attracting nature lovers and spa enthusiasts to this coastal corner of the San'in-Kinki National Park.
Insider tip — Mikata Onsen sits beside the Mikata Five Lakes in western Hyogo, a UNESCO-recognized wetland area where five interconnected lakes form a brackish ecosystem. The bicarbonate spring waters at 40°C complement the area's wellness-focused resort culture. Dawn kayaking on the mirror-flat Suigetsu Lake followed by an onsen soak is the quintessential local sequence. A viewing tower overlooking all five lakes is a short walk from most bath facilities.
