The park is situated directly above an active geothermal field that has been utilized for centuries for both bathing and traditional steam cooking.
Local geothermal activity in the Kannawa area produces constant steam, which is often visible rising from the ground near the park's perimeter.
The park layout incorporates traditional Japanese landscaping elements designed to withstand the acidic mineral content of the local geothermal vapors.
It is frequently used by locals as a cooling-off point after visiting the neighboring commercial hell-spring attractions.
Kannawa Jigoku Area Park is a public green space located in the heart of Beppu’s historic steam-vent district. The park features footbaths (ashi-yu) fed by natural geothermal water, reflecting the area's volcanic landscape. It serves as a community hub near the dense concentration of Kannawa's famous 'hell' hot springs. The grounds are designed to showcase the contrast between landscaped recreational areas and the subterranean thermal activity characteristic of Oita Prefecture. Visitors can view the rising steam clouds that define the surrounding Kannawa neighborhood from within the park limits.
The elevated viewing points within the park that frame the background of steam rising against the town buildings.
Bring a small hand towel for the footbath, as they are not always available on-site.
Visit during the shoulder season to avoid the intense humidity that lingers in the valley during mid-summer.
Wear slip-on shoes for easier access to the footbath facilities.
Do not attempt to touch or bathe in the steaming vents outside designated park facilities due to scalding temperatures.
Rinse feet before using the communal footbaths; maintain a quiet demeanor as it is a neighborhood park.
