If you’ve ever dreamt of soaking in steamy water surrounded by mountains or beneath the stars, welcome to the world of the bathhouse Japanese, or santo and onsen. Deeply rooted in tradition and wellness, Japanese bathhouses are more than a place to get clean—they’re a cultural ritual, social hub, and a healing experience.
Whether you’re visiting Japan or simply curious about its bathing traditions, this guide will walk you through everything you need to know about bathhouses in Japan—from their origins to etiquette and where to experience them.
What Is a Bathhouse Japanese?
A Japanese bathhouse, traditionally called a sento, is a public facility where people bathe in large communal tubs after washing themselves. While onsen (hot springs) are naturally heated by geothermal activity, sento uses heated tap water.
Both offer a similar communal bathing experience, but onsen are known for their mineral-rich waters and scenic settings, often located in mountainous or rural areas.
A Brief History of Bathhouses in Japan
- 6th Century: Bathing rituals were influenced by Buddhist practices, emphasizing purification.
- Edo Period (1603–1868): Communal bath houses flourished in urban centers.
- Post-War Japan: Bathhouses became essential in densely populated cities where private baths were rare.
- Modern Day: With modern homes having private baths, bathhouses now offer relaxation, nostalgia, and cultural preservation.
