The onsen — Japan's volcanic hot-spring bath — is one of the country's defining experiences, and the one clients are most nervous about. The nerves are unnecessary: the rules are few, logical and easy to brief in advance. Agents who send clients a two-minute etiquette primer turn hesitation into the highlight of the trip. Here is the briefing we give every first-timer.
The core rules
- Wash before you soak. Every onsen has a row of seated shower stations. Clients wash and rinse fully there first; the bath itself is for soaking, not cleaning.
- No swimwear. Bathing is nude, with baths separated by gender. This is the point most first-timers worry about and forget within five minutes — the atmosphere is entirely unselfconscious.
- The small towel stays out of the water. Guests carry a hand towel for modesty walking around; fold it and rest it on your head while soaking, or leave it at the side.
- Hair up, phones away, voices low. Tie long hair out of the water. Onsen are quiet, screen-free places.
- Hydrate and pace yourself. Waters run 38–43°C; advise clients to limit each soak to 10–15 minutes, especially after sake at dinner.
The tattoo question
Traditional onsen historically refuse visible tattoos. The practical answers, in order: - Book a private bath (kashikiri or family bath) — rentable by the hour at many ryokan and bathhouses; also the answer for couples and for clients who prefer privacy. - Choose a ryokan room with its own open-air bath — the standard solution on luxury programs. - Cover small tattoos with waterproof patches, sold in Japan for exactly this purpose. - Pick tattoo-friendly onsen — a growing list, which Explera tracks town by town.
Where to send first-timers
- Hakone or Kinosaki — the classic introductions; Kinosaki's seven public bathhouses are walked between in yukata, and the town is exceptionally welcoming to international guests.
- A ryokan with in-room baths — zero-anxiety onsen for honeymooners and multigenerational families.
- Kurokawa Onsen (Kyushu) or Nyuto Onsen (Tohoku) — for repeat visitors ready for the rustic, atmospheric version.
- Winter programs — snow falling on an outdoor bath is the format at its absolute best.
