Onsen Etiquette Tips
♨️ Tattoo policy
Many onsen prohibit tattoos. Private bath (kashikiri buro) rentals are available at most ryokan for guests with tattoos. Call ahead to confirm policy before booking.
♨️ Bathing procedure
Always wash your body at the shower stations before entering the shared bath. No swimwear allowed in traditional onsen. Enter quietly and do not make loud conversation.
♨️ Best time to bathe
Early morning (6–8 AM) and late night (9–11 PM) are the quietest times. Avoid peak hours (4–6 PM) at public baths when local day-trippers visit.
♨️ Towel etiquette
Bring the small towel to cover yourself while walking, but don't put it in the bath water. Fold it and place it on your head or to the side while bathing.
♨️ Hydrate
Onsen water is hot and mineral-rich. Drink water before and after bathing. Limit sessions to 15–20 minutes. Elderly travelers and those with heart conditions should consult a doctor.
♨️ Yukata etiquette
Most ryokan provide yukata (light cotton kimono) for guests to wear around the inn and in some onsen towns. Left side always over right (right over left is for the deceased).

Frequently Asked Questions
What is the difference between onsen and sento?
Onsen are natural hot springs with mineral-rich water from geothermal sources. Sento are public bathhouses using regular heated tap water. Onsen have therapeutic properties and are often in scenic natural settings, while sento are urban community facilities.
Can tourists with tattoos go to onsen in Japan?
Many traditional onsen prohibit visible tattoos, though this is changing. Options include: private bath (kashikiri) rentals, onsen that explicitly welcome tattoos, or covering small tattoos with waterproof bandages. Research each facility beforehand.
How far in advance should I book a ryokan at a popular onsen town?
For peak seasons (Golden Week early May, Obon August, New Year, Cherry Blossom April, Autumn Foliage Nov), book 3–6 months in advance. Off-peak weekdays are more flexible. Top ryokan like Fujiya in Ginzan or Kyomachi in Kinosaki book out quickly regardless of season.
What does "ryokan" include in its price?
Most ryokan prices include dinner and breakfast (kaiseki multi-course meals), yukata use, access to in-house onsen, and sometimes a welcome drink or seasonal sweets. Per-person pricing includes all this plus the room and bath access.
Which is the most famous onsen town in Japan?
Hakone, Beppu, and Kinosaki are the three most famous among both domestic and international travelers. Hakone wins for convenience from Tokyo and Mt. Fuji views; Beppu for sheer variety; Kinosaki for authentic old-Japan atmosphere.
Can children use onsen?
Yes, children can use onsen though some facilities set a minimum age. The water temperature (40–45°C) can be intense for young children. Many ryokan offer family bath options. Children under school age often need to be accompanied by a parent.
