Onsen areas are regions in Japan with natural hot springs. These hot springs are rich in minerals and are heated by geothermal activity. Onsen areas often have multiple hot spring baths, public bathhouses, and traditional inns (ryokan).
Onsen areas are spread across Japan, with each region having unique water qualities and scenic surroundings. Some are located in the mountains, offering beautiful views and serene environments, while others are by the sea or nestled in quiet valleys.
