About this place

Oito Jigoku is a hot spring area located within the Unzen Onsen region, known for its characteristic white steam and the strong scent of sulfur that envelop the site. The landscape features exposed rocky ground from which hot spring waters bubble up, creating visible steam vents that can be observed closely along the designated walking paths. These paths are well-maintained, allowing visitors to safely view the dynamic geothermal activity.

The name “Oito Jigoku” comes from a local legend involving a woman named Oito, who was executed after murdering her husband in the castle town of Shimabara. Around the time of her execution, heightened geothermal activity began in the area, and the name was given as a form of caution. Informational signs provide details of this story and the history behind the place, and visitors often pause to read these as they stroll through the area.

On cloudy days, the combination of fog and steam creates a unique, white-shrouded atmosphere that envelops the surroundings, obscuring the rocky terrain in a misty veil. The walking routes connect to other nearby hot spring sites, enabling a continuous circuit for exploration through the volcanic landscape.
