The geyser is officially recognized as a Place of Scenic Beauty by the Japanese government.
The water contains high concentrations of chloride, which leaves mineral deposits on the surrounding rocks.
The name 'Tatsumaki' translates to 'tornado' or 'twister' in Japanese, referencing the swirling nature of the eruption.
Unlike other hot springs in the region that flow continuously, this site is strictly an intermittent erupting spring.
The eruptive force is driven by the pressure of underground thermal gases accumulating in a narrow conduit.
Tatsumaki Jigoku is a rare, naturally erupting geyser located in the Kannawa district of Beppu. It is one of the designated Beppu Hells, a collection of geothermal hot springs. The geyser erupts with a high-pressure jet of hot water reaching temperatures of approximately 100 degrees Celsius. Due to the site's geology, a rock roof prevents the geyser from spraying its full potential height of 50 meters, limiting it to a vertical burst of roughly 6 to 10 meters. Eruptions occur at relatively predictable intervals, typically repeating every 30 to 40 minutes. The viewing area is enclosed by a circular stone wall to protect spectators from the scalding spray. It is classified as a national scenic spot of Japan due to its unique geothermal activity.

Check the eruption schedule board immediately upon arrival to plan your waiting time.
The viewing area is partially exposed to weather, so carry a light rain jacket if the forecast is uncertain.
The spray carries fine mist; protect camera lenses and electronic devices during the eruption.
Do not attempt to touch the water or cross the stone barrier, as the geyser temperature is dangerous.
Open daily throughout the year with no seasonal closures.
Stay behind the stone containment wall at all times for safety due to the high temperature of the water.
