All about Japan - Onsen: Volcanic Hot Springs
What is an onsen?

An onsen (温泉 - hot spring) is a hot spring of volcanic origin. It allows you to relax, free yourself from stress and fatigue and has several medicinal and regenerating properties for the body.
This bath of almost 50°C is often located outside, in a heavenly environment. The onsen has been very present in Japanese culture for millennia, particularly for its effects on the skin and health.
Onsen ≠ Sento (indoor public bath with non-natural water sources).
