Onsen (温泉) are Japanese hot spring baths - natural geothermal springs used for bathing. They have distinct cultural practices including specific towel etiquette.
Onsen Towel Etiquette
The small tenugui towel serves multiple purposes:
Before bathing:
- Used to wash thoroughly (you must clean before entering onsen)
- Provides modesty when walking to the bath
During bathing:
- Kept OUT of the water (never submerged)
- Often folded and placed on the head
- Or set aside at the bath's edge
After bathing:
- Light drying
- Often supplemented by larger towels in changing areas
Why the Small Towel?
Japanese bathing culture prioritises:
- Hygiene (small towel for washing, not contaminating bath)
- Modesty (covering when walking)
- Tradition (tenugui is the historical form)
Onsen vs Sento
- Onsen: Natural hot springs (volcanic/geothermal)
- Sento: Public bathhouses with heated tap water
Similar etiquette applies to both.
