Onsen etiquette for first-timers, step by step
You want to try a hot spring but worry about doing something wrong in front of strangers.
Seasons and when to go
Outdoor onsen in winter or summer
You picture a hot spring under open sky and wonder which season your body will enjoy.
Winter is the classic season for an outdoor onsen, because hot water against cold air feels special. Summer works too, early or late in the day. For heat-used bodies, winter is more surprising and summer is more tiring, so plan short soaks either way.
What does winter feel like?
The water is hot, but the walk between the room and the bath is cold. Tokyo’s January mean is 5.4 °C 1, and onsen towns in the hills run colder. Wear a robe, bring slippers and keep warm until you enter.
Soak for short periods, then rest. Avoid getting chilled when you leave the water.
What does summer feel like?
Tokyo’s August mean is 26.9 °C 1. A hot bath at midday is tiring, especially for elders. Go early or after dinner, drink water before and after, and keep soaks short.
How do modesty and private baths fit in?
Onsen bathing is usually without clothing and in single-gender baths. If that is uncomfortable, choose a ryokan with a private bath, available by the hour or in the room. Read onsen modesty and private bath options and private open-air bath rooms.
For the rules of shared baths, see onsen etiquette for first-timers and bathing etiquette.
Which season should you choose?
Choose winter if you want the classic open-air feel and are ready for cold walks. Choose summer if you prefer warm nights and do not mind choosing off-peak hours. Either way, Hakone offers both shared and private options, and the onsen glossary entry explains the basics.
Tell us your season and who is bathing, and we will suggest an onsen stay with the right balance of open-air feel and privacy.

Questions travellers ask
Is a winter onsen too cold to enjoy?
The water is hot, so the bath itself feels wonderful, but the walk and the changing area are cold. Tokyo's January mean is 5.4 °C, and onsen towns in the hills are colder. Keep warm until you step in, and stay in short sessions.
Is summer onsen comfortable?
It can be, early in the morning or at night when the air has cooled. Midday heat makes a hot bath tiring, especially for elders. Drink water before and after, and keep each soak short.
What if we prefer privacy?
Many ryokan have private baths you book by the hour or have in the room, which suits modesty, families and anyone unsure about shared baths. Ask about this when you enquire, as availability varies. We help you request it.
