Overview (history, characteristics, attractions)
Unzen Jigoku is a fumarolic zone (hot mud zone and fumarole group) that spreads out near the Unzen hot spring town in Unzen City, Nagasaki Prefecture. Volcanic activity causes high-temperature steam and hot mud to spew from the ground, and the smell of sulfur and the rising steam of hot water give it the nickname "hell," making it a popular tourist spot since ancient times.
Historically, the Unzen area has been affected by volcanic activity, and retains the memories of several major eruptions and disasters, such as the earthquake and mudslides of 1792 and the eruption of Mount Fugen in the 1990s. Currently, walking trails and observation spots have been developed, allowing you to observe the fumes up close, and the surrounding hot spring towns offer great opportunities to enjoy bathing and dining.
Highlights
