Onsen (Hot Spring) Etiquette for First-Timers

Onsen and public baths (sento) are for soaking, not washing. Use the shower stations to wash and rinse thoroughly before entering the bath.

Bathing is typically done without swimwear. A small modesty towel is common to carry (not to dip in the water) and is often available to rent or buy on site.

Many onsen still restrict visible tattoos, though this is loosening in tourist-heavy areas. If you have tattoos, it's worth checking a specific facility's policy before you go — some offer cover stickers, others are fully tattoo-friendly. (Verify locally — policies vary by facility and change over time.)
