Mount Unzen, one of Japan's leading active volcanoes, is located in the center of the Shimabara Peninsula. Its rich nature is so great that it was designated as the first national park in Japan, and Unzen Onsen, where the entire town is enveloped in steam, is a historic hot spring town that was once a popular summer resort for foreigners during the Meiji period.

Unzen shows different faces as the seasons change.
