What Is an Onsen?
Definition of Onsen
An onsen is a natural hot spring bath filled with mineral-rich, geothermally heated water. It’s a place to relax, refresh, and feel close to nature.
Difference Between Onsen and Sento
A sento is a regular public bath using heated tap water, often in cities.
An onsen uses natural spring water and offers a more traditional, scenic experience.
Cultural Meaning in Japan
Onsens symbolize purity and harmony in Japanese culture — not just bathing, but quiet reflection.
