Before you enter the bath
An onsen is a place to soak, slow down and share a quiet space with others. The routine may feel unfamiliar on a first visit, but you do not need to know every custom in advance. Start by reading the facility’s signs and following any directions from staff. Rules can differ between inns, day-use hot springs and individual baths, so local guidance takes priority over a general etiquette guide.
Many communal baths have separate changing rooms and bathing areas for men and women, though arrangements vary. Confirm which entrance you should use before passing through the curtain or doorway. In a typical communal onsen, visitors bathe without swimwear. Leave your clothes and larger belongings in the changing area, using the basket or locker provided. Bring a small towel into the bathing area if you have one; leave your larger drying towel somewhere it will stay dry. Phones and cameras are best left outside the bathing area to protect everyone’s privacy.
Wash first, then soak
The most important step is to wash before entering the shared water. Look for the washing stations, which usually have a stool, a shower or tap, and sometimes soap and shampoo. Sit down to wash, taking care not to splash people beside you. Rinse away all soap and shampoo before heading to the bath. If you have long hair, tie it up so it stays out of the water.
Enter the bath gently rather than jumping or diving in. Hot water can feel intense at first, so take your time and step out whenever you need a break. The bath is for soaking, not washing: do not use soap in it or rinse your towel there. You can place a small towel beside the bath or rest it on your head, but keep it out of the shared water. If you are unsure where to put it, notice the available ledges and follow posted instructions.
Share the space considerately
A calm, low-key manner helps everyone enjoy the bath. Speak quietly, give other bathers room and avoid splashing. Do not reserve a washing station with your belongings while you soak, especially when the area is busy. Before returning to the changing room, lightly dry yourself with your small towel if possible so you do not carry too much water onto the floor.
You may see several pools with different temperatures or an outdoor bath alongside an indoor one. Follow the signs for each area rather than assuming they all work the same way. Some facilities have additional spaces with their own rules. When in doubt, pause and look for instructions or ask a staff member. Being attentive matters more than performing every detail perfectly.
Check tattoo policies before you travel
Tattoo rules vary considerably by facility. Some welcome tattooed guests, some allow small tattoos if they are covered, and others do not permit tattoos in communal baths. A cover that works at one onsen may not be accepted at another, particularly if it cannot fully conceal the tattoo. Do not assume a policy based on the size or meaning of your tattoo.
If you have tattoos, check the facility’s own information before booking or making a special trip. If the wording is unclear, contact the staff and explain the approximate size and location of your tattoos. Ask whether covers are permitted and, if so, what kind. A private bath, sometimes offered for a reserved time or as part of a room, may be another option, but confirm its availability and rules in advance.
Let the visit be simple
For a first visit, choose a place whose instructions you can understand and allow enough time that you do not feel rushed. Pack a change of clothes and check whether towels and washing supplies are provided or available to rent. At the entrance, it is fine to ask a short practical question rather than guess.
The rhythm is straightforward: change, wash thoroughly, rinse, soak and dry off before dressing. If you respect the posted rules and the people sharing the space, you can focus less on getting everything exactly right and more on the pleasure of a quiet bath.
