Nagasaki Onsen Unzen Furusato

Nagasaki Onsen Unzen Furusato is a thermal bathing facility at Unzen in Nagasaki Prefecture, set in the volcanic highland of the Shimabara Peninsula where the Unzen volcanic complex produced Japan's deadliest historical volcanic disaster in 1792 when the collapse of the Mayuyama lava dome triggered a massive tsunami that killed nearly 15,000 people in the Ariake Sea, and where the active Heisei Shinzan lava dome that grew from 1990 to 1995 remains among Japan's most closely monitored volcanic features. Unzen's Christian history is among the most tragic in Japanese history, as the site of the Unzen martyrdom of 33 Christian converts in 1622 who were tortured with boiling volcanic water and sulfurous steam in the jigoku (hell) thermal vents before execution during the intense persecution of Christianity in early Edo Japan, a memory commemorated in a monument at the Unzen Jigoku volcanic thermal field. The sulfurous spring waters of Unzen Furusato emerge from the same volcanic system that has shaped this dramatic peninsula's history in fire, faith, and geological transformation, offering bathing in a setting of volcanic power where the memory of Christian martyrdom, spectacular volcanic scenery, and Nagasaki Prefecture's extraordinary cultural history converge in one of Kyushu's most historically layered thermal destinations.
