Onsen Etiquette & Why Public Baths Ban Tattoos & Swimsuits
Undress completely in the locker room. Swimwear is never permitted in communal baths.
Sit on the low wooden stool to wash and rinse off all soap before entering the bath.
Keep your small towel & hair out of the spring water—place the folded towel on your head.
Have tattoos or traveling as a couple? Book an in-room private cypress bath for zero restrictions.
Soaking in a natural volcanic hot spring (Onsen) is the quintessential Japanese luxury ritual. However, first-time international guests are often surprised by three strict communal bathhouse rules:
- No Swimsuits Permitted: All communal baths are entered completely unclothed. Fabric fibers and laundry detergents are considered contaminants to pure geothermal spring water.
- Visible Tattoos Are Restricted (~80% of Public Baths): Due to historical associations in Japan, most traditional public onsens and hotel communal spas deny entry to guests with tattoos (unless small enough to conceal beneath a waterproof skin patch).
- Gender-Separated Wings: Men (marked 男 with a blue curtain) and women (marked 女 with a red curtain) bathe separately—meaning couples and families cannot soak together in public baths.
