We're a Guide for People Who Don't Already Know

Japan has over 3,000 onsen. Most travel content about them is written for people who grew up bathing in them — people who already know the rules, already know what to expect, and don't need an explanation of why everyone is naked.

We wrote Onsen Experiences for everyone else: first-time visitors anxious about doing something wrong, tattooed travelers who have been turned away before, day-trip planners who need real logistics, not inspirational copy.

Our job is to fill the gaps. We explain the things that are obvious to Japanese regulars and completely unfamiliar to everyone else. We verify tattoo policies so you don't get turned away at the door. We tell you when it's crowded, when to book ahead, and when you can walk in. We recommend specific venues based on what you're actually trying to do.

How We Work

We earn a commission when you book through our links on Viator. This is how we keep the site running. It doesn't affect your price — you pay the same amount whether you book through us or go directly to Viator. We don't recommend venues based on commission rate. We recommend venues we'd actually send a friend to.

The commission is a byproduct of the recommendation, not the reason for it. If a venue is bad, we say so. If a venue doesn't accept tattoos, we don't list it as tattoo-friendly. We maintain our own verification standards separate from whatever Viator pays us.

Onsen Etiquette — The Short Version

Onsen are public bathing facilities. The rules are straightforward once you know them:

• Wash before you enter the bath. Every onsen has a washing area with soap, showers, and stools. Use them. This is non-negotiable.
• Leave your swimwear outside the bath. Onsen are naked bathing facilities. Some private venues differ — check the listing.
• Keep your head above water. The bath is for soaking. Don't submerge your head unless the bath is specifically designed for it.
• Tattoos: ask before you book. Some onsen accept tattoos, some don't. We list only venues with confirmed policies. When in doubt, contact the venue directly before booking.
• Be quiet in the bath. Conversation is fine. Loud talking, splashing, and disruptive behavior are not.
• No photography. Onsen are private spaces. Photography inside the bathing area is prohibited everywhere we've found.

The list sounds more complicated than it is. Once you're there, it feels natural. The staff will guide you on anything that matters. If you're unsure, ask at the entrance — most staff are accustomed to first-timers.

Our Approach to Onsen

Japan's onsen culture is genuinely one of the most restorative practices in the world. The geology that makes the country so volcanically active also fills it with natural hot springs. Getting to experience that — really experience it, without anxiety, without confusion — is what this site is for.

We think you should know what you're walking into before you get there. That's the whole idea.
