Major city · Japan
Unzen雲仙市
Half-day trip from Nagasaki or Shimabara: see the Unzen Hells, soak in an onsen, then move on. One night only if you want a full day of hiking Mount Unzen.
Unzen is a small onsen town on the Shimabara Peninsula, part of the Unzen-Amakusa National Park. Its main draw is the Unzen Hells — a volcanic area with boiling springs and a dark history of Christian martyrdom. The town also offers hot-spring bathing (Unzen Onsen and Obama Onsen) and hiking on Mount Unzen. Most visitors come from Nagasaki or Shimabara for a few hours; an overnight stay suits those who want to hike or relax in an onsen ryokan.
