How to use an onsen in Japan (first-timers)

A practical, step-by-step guide to visiting an onsen for the first time: tickets, washing, towels, and what to expect.

Visiting an onsen can be one of the best parts of a Japan trip, but the routine is different from a typical swimming pool or spa. Most facilities follow the same flow: change, wash, soak, and relax.

1) Check the rules (especially tattoos)

Before you pay, look for posted rules near the entrance. If you have tattoos, do not assume it is okay—policies vary by facility and can change. If you cannot find an official policy, ask staff or choose a facility with a clear, public policy statement.

2) Pay and enter the bathing area

Many onsen use a ticket machine. Pick the correct option (general admission/child, time-limited plans, towel rental), then hand the ticket to the front desk. Store shoes in a locker, then head to the correct changing room.

3) Wash thoroughly before soaking

This is the most important step. Sit at a washing station, rinse your body, and wash with soap and shampoo. Rinse again completely. Only then enter the bath.

4) Keep towels out of the water

Bring a small towel to the washing area. In the bath, keep it on your head or on the side—do not soak it in the water.

5) Soak quietly and take breaks

Onsen water can feel very hot. Start slowly, take breaks, and drink water. Keep voices low and avoid splashing.

6) After the bath

Dry off before returning to the changing area to avoid dripping water. Rehydrate. Some facilities have relaxation rooms, restaurants, or massage services—enjoy at your own pace.
