What Exactly is an Onsen?
An onsen (温泉) is a traditional Japanese hot spring naturally heated by volcanic activity. These aren’t just ordinary hot tubs – they’re mineral-rich waters with healing properties deeply rooted in Japanese spiritual traditions.
Cultural Significance
In Japanese culture, onsens are tied to purification concepts in Shintoism and Buddhism. The experience transcends bathing, offering a chance to find harmony with nature and restore both body and mind.

Essential Onsen Etiquette Tips
