Onsen Basics
How Tokyo Onsen Work
The short version of what you need to know before you go.
1. Wash before you enter
Every onsen has a washing area. You must clean yourself before stepping into the bath.
2. No swimwear in the water
Onsen are naked bathing. Swimwear is not worn in the bath.
3. Tattoos — check first
Many restrict visible tattoos. We only list venues with confirmed tattoo-friendly policies.
4. Don't submerge your head
Keep your head above water. The bath is for soaking.
