HAKONE / DAY ONSEN / THE TATTOO RULES, TRANSLATED

English guides will tell you that Hakone has tattoo-friendly hot springs. That is true and almost useless, because the rules are specific in ways no summary survives. One place will admit you with a tattoo but only if you are the only tattooed person in the building — and if you and a tattooed friend arrive separately and meet inside, you are both asked to leave. Another will let you in if, and only if, two of their cover stickers hide it completely. A third removed its restrictions entirely in 2025 and says so on its front page. All three sentences are on the operators’ own Japanese websites. Here they are in English.

Can you get in with a tattoo?

It depends entirely on which building you walk into, and the three big names in Hakone sit at three different points on the scale. This table is translated from their own Japanese pages.

Facility	Official position on tattoos	Practical reading
Hakone Yuryo (Hakone-Yumoto)	States on its front page that it is promoting tattoo-friendliness and has lifted its bathing restrictions for tattoos	Walk in. No covering, no conditions, no conversation. The simplest answer in Hakone
Tenzan Tojikyo (Okuyumoto)	Will not refuse you for a tattoo, but admits only one tattooed person at a time. If two tattooed people are inside, both are asked to leave — even if they arrived separately and met by chance. Asks you to wear something over it in the common areas	Fine alone. Impossible as a tattooed couple. Also no tour groups, and groups of any kind capped at six
Yunessun (Kowakien)	Refuses tattoos in principle, including stickers and paint. Swimsuit zone: allowed if covered, e.g. by a rash guard (paid rental available). Nude bath “Mori no Yu”: allowed only if two of the facility’s own paid cover stickers hide it completely. Otherwise, use a private bath (8 rooms, reservation required)	Workable, but measure your tattoo first. Two stickers is not very much coverage

Notice what is not in that table: nobody is “tolerant”. Each has written a precise rule and will apply it at the counter, in Japanese, while a queue forms behind you. Decide which building you are going to before you get on the train.

The “one tattooed person” rule, in full

Tenzan is the most atmospheric day onsen in Hakone — a river valley, outdoor pools, a genuinely old-fashioned toji bathing place rather than a leisure facility. It also has the rule most likely to ruin your afternoon, and English write-ups consistently soften it. Here is what its own page actually says, in summary:

• A tattoo is not in itself a reason for refusal
• But use is limited to one tattooed person. Regardless of gender, if more than one tattooed guest is present, entry is refused
• Arriving separately does not help. If you end up inside at the same time, you will be asked to leave, and “we just happened to meet here” is explicitly not accepted
• While in the building, you are asked to wear something over it out of consideration for others
• The stated reason is to avoid the impression of intimidation that a group of tattooed guests can create

Two further rules at Tenzan that catch foreign visitors, both from the same page:

• Groups are capped at about six adults, and splitting up to get around it does not work
• Tour groups and travel agents are refused outright. It describes itself as a toji-ba, a curative bathing place, not a leisure facility — which is also why you will never find it bookable on an OTA. Come as an individual or not at all

If you are a solo traveller with tattoos, Tenzan is arguably the best bath in Hakone and it will take you. If there are two of you, go somewhere else and do not improvise.

What do cover stickers actually buy you?

Less than the internet suggests. The widely repeated advice — “small tattoos are fine if you cover them with a sticker” — is not how Yunessun has written its rule. Its FAQ refuses tattoos in principle and specifically includes stickers and paint in that refusal, then carves out two exceptions:

• The swimsuit zone (the famous wine and coffee baths): wear a rash guard or similar so the tattoo is not visible. Rash guards can be rented for a fee
• Mori no Yu, the nude bath: permitted only when two of the facility’s own paid cover stickers completely hide the tattoo. Not your stickers. Theirs, and two of them
• If it cannot be completely covered: the official answer is the private baths — eight rooms, reservation required

So measure it. Two cover stickers will handle a wrist or an ankle. They will not handle a half-sleeve, and arriving to be told so at the counter is the single most avoidable disappointment in this article.

The reliable answer: book a private bath

If your tattoos are large, or there are two of you, or you simply do not want the conversation, a kashikiri — a private open-air room you book by the hour — removes the question entirely. Hakone Yuryo has nineteen of them, which it describes as the largest such collection in the Tokyo area, in three sizes:

Room type	Capacity	Weekday, 120 min	Weekend / holiday
Ichi-no-maki (7 rooms)	up to 2	¥10,400	¥11,400
Ni-no-maki (8 rooms)	up to 4	¥12,400	¥13,400
San-no-maki (4 rooms)	up to 4	¥14,400	¥15,400

The details that matter, from the same page:

• Reservations open one month ahead and close at 15:00 the day before online; after that, by telephone only
• Minimum two hours
• Using the big public bath as well costs extra — ¥1,000 on weekdays, ¥1,300 at weekends
• Every room has its own heated and air-conditioned rest area
• Golden Week, mid-August and new year are charged at weekend rates
• Guests under 18 may not use the rooms unaccompanied, and guests in nappies cannot bathe

For two people for two hours, ¥10,400 works out at ¥5,200 each — about three times a public bath ticket, for a private open-air bath in a wooden room with nobody else in it. For a couple where one or both have tattoos, it is the obvious purchase and it is bookable in advance, which almost nothing else here is.

Which day onsen should you choose?

Hakone Yuryo — the default, and the tattoo answer

Three minutes from Hakone-Yumoto station by free shuttle bus, which matters more than it sounds when the alternative is a bus timetable in Japanese. A large wooden satoyama-style complex: indoor baths, open-air baths, pot baths, a sauna, an irori restaurant, a huge rest hall, and the nineteen private rooms. Adults ¥1,700–¥1,800 on weekdays and ¥2,000–¥2,200 at weekends; primary-school children ¥1,000; children below school age are not admitted to the main bathhouse at all — they need a private room. Towels are not included (bath towel ¥550, face towel ¥300, yukata ¥300). Open daily, 10:00–20:00 on weekdays and until 21:00 at weekends.

from about US$11 · Hakone-Yumoto, free shuttle · no tattoo restrictions · 19 private rooms bookable separately on the operator’s own site · note: this Klook listing is new and has a single review, from a visitor whose voucher showed as already used — keep the confirmation screen and arrive with it open

Yunessun — only if you want the theme park

This is two things sold as one: a swimsuit water park with novelty baths, and a conventional nude onsen called Mori no Yu. The water park is a day out with children, not a hot spring experience, and its reviews say so — 4.5 from 417, with the complaints concentrated on crowds and small pools rather than anything being broken.

from about US$9 · Kowakien · 4.5 from 417 reviews · 2.4% rated 1–2 stars · check whether your hotel already includes entry before buying — one reviewer could not get a refund after discovering it was free with their stay

Konohana no Yu — if you want Fuji from the bath

Not in Hakone but at Gotemba, on the far side of the same day trip, and the reason to go is the view: an open-air bath looking straight at Mount Fuji. It pairs naturally with a Fuji day and with the outlet mall next door if someone in your group wants shopping. Check its tattoo policy directly before you commit — it is a separate operator from the three above and I have not verified its rule from a primary source.

from about US$12 · Gotemba · open-air bath with Mount Fuji view · tattoo policy unverified — ask first

Tenseien — the quiet one at Hakone-Yumoto

A ryokan that sells day-use bathing, within walking distance of the station, and the least crowded of the options here simply because it is not famous. Only two reviews on Klook, so treat the rating as meaningless and the price as the information.

from about US$14 · Hakone-Yumoto · ryokan day-use · only 2 reviews — rating not meaningful

Tenzan — the best bath, with conditions

You cannot book it here or anywhere else, because it refuses travel agents. Take a bus or taxi from Hakone-Yumoto, bring cash — almost everything inside is cash only and there is no ATM nearby — and bring a face towel, which is required, not optional. Yukata rental is ¥500. Go alone, and go on a weekday.

What do the bad reviews say?

The bookable Hakone onsen tickets have far fewer complaints than the bus tours I have looked at elsewhere, which makes sense: a ticket is a simpler product than a day. Yunessun, the only one with a meaningful sample, has 10 one- or two-star reviews out of 417 — 2.4%. The themes:

• Crowding. Reviewers describe being packed in, pools too small to enter, and the reality not matching the photographs. This is a weekend and school-holiday problem
• Paying for something that was free. One reviewer’s hotel in the area included entry; they had already bought a ticket and could not get it refunded. Check your accommodation first
• Transport delays eating the day. A reviewer delayed by a rail accident missed the lunch buffet included in their ticket and could not recover the cost from either the facility or the platform
• The naked bath is the good part. Several reviewers who disliked the theme park said Mori no Yu was still worth it — which, if you have tattoos, is the part with the sticker rule

Is the Hakone Freepass worth it for a day trip?

The Hakone Freepass costs ¥7,100 for two days from Shinjuku (children ¥1,600) and covers unlimited travel on eight forms of transport in the area — the mountain railway, cable car, ropeway, buses and the pirate ship on Lake Ashi — plus discounts at around seventy facilities. Odakyu has sold over ten million of them.

The catch that catches everyone: the Romancecar is not included. The pass covers the ordinary train. If you want the limited express, you buy a separate limited-express ticket on top.

For a day trip whose point is a bath, the pass is usually the wrong purchase. If your plan is Shinjuku to Hakone-Yumoto, a day onsen three minutes from the station, and home, you are using two train journeys and a free shuttle bus, and a return ticket is cheaper. The pass earns its money on the “golden course” — railway, cable car, ropeway over Owakudani, boat across Lake Ashi, bus back — where you ride five different things in a loop. Decide which day you are having, then buy the ticket for that day.

about US$44 on Klook against ¥7,100 at the counter — close enough that the exchange rate on the day decides it · 2 days from Shinjuku · Romancecar extra

If you would rather someone else drive, the guided version of the golden course from Tokyo runs about ¥12,000 and includes the Lake Ashi cruise and the ropeway: Mt Fuji and Hakone with cable car and cruise, 4.6 from 524 reviews. Note that the ropeway over Owakudani closes in high wind and for volcanic activity, and no tour refunds you for that.

Things that will catch you out

• Towels are rarely included. At Hakone Yuryo a bath towel is ¥550 and a face towel ¥300. Bringing your own saves more than it sounds across a family
• Tenzan is cash only, with no ATM nearby. Bring more yen than you think
• Small children may not be allowed in the main bath at all. At Hakone Yuryo, below primary-school age means a private room or nothing
• Private rooms close for booking at 15:00 the day before. After that it is a phone call in Japanese
• The ropeway closes in bad weather, and the Owakudani leg is subject to volcanic conditions. If the golden course is your plan, have a second plan
• The last entry is well before closing — typically an hour. A 19:00 arrival for a 20:00 close does not work
• Check your hotel first. Some accommodation in the area includes Yunessun entry, and a ticket bought in advance is not refundable once you find out

Quick answers

Planning the rest of the trip

Hakone pairs naturally with a Mount Fuji day trip, and the same warning applies to both: the mountain is visible on far fewer mornings than the photographs imply, and no tour refunds you for cloud. Japan turns people away at the door more often than visitors expect, and almost always over a rule written down somewhere in Japanese: here it is tattoos, and on Tokyo’s street go-kart tours it is the exact format of your driving permit, with no refund either way. If you are doing either as a day trip out of Tokyo with your bags still in tow, the luggage problem is worth solving before you set off, not after.

Tattoo rules, prices and opening hours were translated from the operators’ own Japanese-language pages on 16 October 2026 — Hakone Yuryo, Tenzan Tojikyo and Yunessun — and the Hakone Freepass fare from Odakyu’s own site. Ticket prices and review counts were read from Klook and Viator the same day. Rules at Japanese bathhouses change without notice and are applied at the counter; confirm with the facility before you travel. Reviews are summarised, not quoted.
