Japanese Onsen Etiquette Guide | Washing, Towels & Bathing Rules

Rules for the Changing Room (Dressing Room)

Before entering the bathing area, you must pass through the changing room (脱衣所, datsu-i-jo). Store all valuables in the provided lockers. Cameras, smartphones, and any device with a camera are not permitted in the changing room or bathing area — this protects the privacy of other bathers.

• Lock valuables, phones, and cameras in the locker before entering
• Keep your belongings tidy in your basket so they do not inconvenience others
• Dry your body thoroughly with your towel before stepping from the wet bathing area back into the dry changing room

Before Entering the Bath: Rinse First (Kakеyu)

Always rinse your entire body before stepping into the communal bath. This is called kake-yu (掛け湯). Using the shower or a wooden bucket (桶, oke) at the washing area, pour water from your feet upward to your shoulders. This removes dirt and grime, and helps your body adjust to the hot water temperature — preventing sudden cardiac stress.

Using the Washing Stations

• Rinse the faucet and showerhead before and after use
• Keep shampoo and soap lather contained — do not splash neighbours
• Do not occupy a washing station for an extended period; be mindful of others waiting
• Rinse the stool and bucket before returning them to their place

Bathing in the Communal Bath

• Never put your towel into the bath water — this is unhygienic and prohibited
• Do not use soap or shampoo inside the bath
• Keep voices low; the onsen is a place of relaxation for everyone
• Avoid monopolising space in the bath, especially during busy periods
