Why go
Hot springs and public baths reveal a social side of travel that a hotel shower cannot. Outdoor rotenburo, inn baths and neighborhood sentō differ in setting, while bathing customs and tattoo policies can affect access before you set out for the day.
The full story
Onsen are hot springs, and volcanic Japan has them in many regions. A stay at a hot-spring inn can include an indoor bath, while rotenburo are outdoor baths that frame the surrounding landscape. Some inns offer reservable private baths, often called kashikiri-buro, for visitors who prefer a separate setting. Sentō are public bathhouses, especially associated with cities. Some remain straightforward neighborhood facilities, while others have developed into larger spa-style complexes. The purpose and atmosphere differ from an onsen, even though both center on shared bathing. Japanese-style bathing is usually done naked in gender-separated facilities. Wash before entering the bath, and treat the water as a place to soak rather than wash. Tattoo policies vary, and some baths restrict entry, so confirm the house rules before making a trip. Choose a private bath if that better suits your group or comfort.
Useful to know
- Wash before entering the bath and keep soap outside the soaking water.
- Check tattoo and private-bath policies directly with the facility before you go.
