Hakone Onsen Guide: Day Baths, Private Baths and Access

JGO! editorial team — WEBMARKS Inc. (Fujisawa, Kanagawa)

For a Hakone onsen day trip, choose a facility by the kind of bathing you want: Tenzan is a day-use hot-spring facility, Hakone Yuryo offers public bathing and separately priced private open-air bath rooms, and Yunessun has a swimsuit area as well as its day-use Mori no Yu hot spring. These options have different prices, age rules, payment arrangements and tattoo conditions, so check the rules for the specific area you plan to use. From Shinjuku, Odakyu describes the Romancecar journey to Hakone-Yumoto as about 80 minutes; the limited-express charge is separate from the basic fare.

Compare Hakone’s day-bathing options

Before comparing prices, decide whether you want a shared bath, a private room, a swimsuit area or an overnight stay. Those choices affect both the total cost and the rules you need to check: for example, Hakone Yuryo’s private-bath charge does not include public-bath admission. The amounts below are the stated facility charges, not a complete trip budget, and should be reconfirmed with the facility before you travel.

The Tenzan and Hakone Yuryo amounts and conditions above were checked against their official pages on November 4, 2026. They do not include travel, meals or separately purchased towels. At Hakone Yuryo, treat the private room and public bath as separate choices when working out the price: using one does not automatically mean you have paid for the other. (Tenzan prices and hours; Hakone Yuryo prices and hours; Yunessun official site)

A practical comparison is to start with the kind of bathing experience you need, then check the facility’s exact rules and your journey cost. Tenzan has a published child rate and is cash only, while Hakone Yuryo has a separate public-bath price and bookable private rooms for groups of two to four. Yunessun is the option in this comparison with a swimsuit area, but its current admission price and operating details should be checked directly rather than inferred from older information. For wider trip planning, compare your transport separately with the Tokyo-to-Hakone journey and Hakone Freepass information, and review onsen etiquette before visiting a shared bath.

Tenzan: a day-use hot-spring facility

Tenzan is in the Hakone-Yumoto, Tonosawa and Hatajuku area, at 208 Yumotochaya, Hakone. The Hakone tourism association describes it as a day-use, free-flowing hot-spring facility and lists parking for 140 cars. Use the tourism association’s Tenzan listing for the location and parking information, and the official Tenzan page for prices, hours and facility details.

The adult admission price is ¥1,450, and the price for children from age one through elementary school is ¥700. The facility states that admission includes consumption tax and bathing tax, and that payment is cash only, so plan to bring cash rather than relying on card payment. Tenzan’s listed hours are 9:00–23:00, with last entry at 22:00; check the official page before setting out in case of a closure or change. (Tenzan official information)

The bathing facilities differ between the men’s and women’s areas. The men’s area has indoor and outdoor baths and a steam sauna, while the women’s area has indoor and outdoor baths, a spring-steam room and a dry sauna. Soap, shampoo and hair dryers are provided, which can help you decide what to pack; the official information does not mean that towels or other items are included in the admission price.

Tenzan has no regular closing day, but it closes for roughly five days in mid-December. If a visit falls around that period, check the current calendar rather than assuming the facility will be open. The Yamaboshi restaurant closes on Wednesdays and Thursdays and does not accept reservations, so do not build a meal plan around a presumed booking or opening day. (Tenzan official information)

Hakone Yuryo: public bathing and private open-air baths

Hakone Yuryo is at 4 Tonosawa, Hakone. It has two distinct bathing choices to consider: a public bath and 19 private open-air bath rooms, arranged in three types for groups of two to four. A private bath can be used on its own, but its charge does not include admission to the public bath. (Hakone Yuryo prices, hours and booking information)

For the public bath, adults are classified as visitors from junior high school age upward. The adult price is ¥1,700–¥1,800 on weekdays and ¥2,000–¥2,200 on weekends and holidays; the elementary-school child price is ¥1,000. Children below elementary-school age cannot use the public-bath building, so families with younger children should not treat the public bath as an available option. Check the facility directly about conditions for a private-room visit with children, because the public-bath rule does not establish the conditions for every other offering. (Hakone Yuryo official price page)

The private rooms have a basic use period of 120 minutes and are intended for groups of two to four, with three room types. Online reservations are accepted from one month before the visit until 15:00 on the preceding day. If you need to make or change a reservation after that deadline, the facility says to contact it by telephone; check the official page for the current contact and booking details rather than assuming online booking remains available. (Hakone Yuryo official price and booking information)

To book, open the official price and booking page, select the room type and date, and check the displayed price for your group. Add public-bath admission only if you also intend to use that area. If you want the public bath, account for its last-entry time: 19:00 on weekdays and 20:00 on weekends and holidays, before the listed closing times of 20:00 and 21:00 respectively. Towels for the public bath are sold rather than rented, and irregular maintenance closures are possible, so confirm both details close to your visit. (Hakone Yuryo official information)

Children, tattoos and swimsuit bathing

Check rules for the exact bathing area you intend to enter rather than assuming that one policy applies across an entire facility. Yunessun has a swimsuit area, and it also identifies Mori no Yu as a day-use hot spring. The two areas have different tattoo conditions, so confirm the current rules with Yunessun before making plans. (Yunessun official site)

In Yunessun’s swimsuit area, tattoos must be covered. For Mori no Yu, tattoos must be completely covered using two designated cover stickers. These are specific conditions for the named Yunessun areas; they should not be treated as a general policy for other Hakone baths. For current details about the areas and admission, consult the Yunessun official site directly.

For families, compare each facility’s child information separately. Hakone Yuryo’s public-bath building is not available to children below elementary-school age, while Tenzan lists a ¥700 admission rate for children from age one through elementary school. Do not apply Tenzan’s age category or price to another facility, and do not assume that Hakone Yuryo’s public-bath restriction also specifies the conditions for using its private rooms; confirm those conditions with the facility when planning a family visit. (Tenzan official information; Hakone Yuryo official information)

Getting to Hakone and planning the booking

Odakyu describes the Romancecar trip from Shinjuku to Hakone-Yumoto as taking about 80 minutes. All seats are reserved, and passengers need both a basic fare ticket and a limited-express ticket. The listed adult one-way limited-express charge is ¥1,200, but that amount alone is not the complete train fare. Check the departure and full fare for your travel date on the Odakyu Romancecar page.

Use the train information as one part of the journey budget, not as the total cost of reaching a bath. The trip time is for the Romancecar journey between Shinjuku and Hakone-Yumoto; it does not include the onward journey to a chosen facility. Check access details for your specific destination and allow for the separate travel costs and transfers that apply to your plan rather than assuming the train arrives at the bath itself. (Odakyu Romancecar information)

For Tenzan, the tourism association lists the address as 208 Yumotochaya and parking for 140 cars. For Hakone Yuryo, the official page gives its location as 4 Tonosawa and provides the current public-bath and private-room information. Consult those facility pages for the exact destination, then check how you will reach it and return from it on your chosen day. (Hakone tourism association: Tenzan; Hakone Yuryo)

If you plan an overnight stay, compare the actual accommodation plan before booking. Room prices, whether meals are included, cancellation conditions and seasonal availability depend on the individual accommodation, and current lodging details are not established by the day-bath prices in this guide. Treat a day-use bath charge as separate from any overnight package, and confirm your facility access and return transport before finalising the plan.

Frequently asked questions

Which Hakone onsen option should I choose for a day trip?

Choose based on the bathing arrangement you want and the rules that fit your group. Tenzan is a day-use facility with published adult and child prices, while Hakone Yuryo offers a public bath and separately priced private rooms for groups of two to four. Yunessun has a swimsuit area, but you should check its current admission, hours and availability on the official site. (Tenzan; Hakone Yuryo; Yunessun)

Can I use a private bath at Hakone Yuryo without paying for the public bath?

Yes. Hakone Yuryo states that its private open-air bath rooms can be used without using the public bath, and public-bath admission is a separate charge. The private-room use period is 120 minutes, with rooms for groups of two to four across three types. Check the room price and availability for your date on the official price and booking page.

Do I need a basic fare ticket as well as the Romancecar limited-express ticket?

Yes. Odakyu says passengers need a basic fare ticket in addition to the limited-express ticket, and all Romancecar seats are reserved. The listed ¥1,200 adult one-way limited-express charge for Shinjuku to Hakone-Yumoto is not a substitute for the basic fare. Confirm the full fare and departure for your travel date on the Odakyu Romancecar page.

Does Tenzan accept card payments?

Tenzan’s official information says payment is cash only. Its listed adult admission is ¥1,450 and its child admission for ages one through elementary school is ¥700, including consumption and bathing taxes. Check the current information before travelling, and bring cash if you plan to pay at the facility. (Tenzan official information)

What should I check before travelling on a possible closure day?

Check the chosen facility’s own official page close to departure because closure information is facility-specific. Tenzan has no regular closing day but closes for roughly five days in mid-December, while Hakone Yuryo notes irregular maintenance closures. If you consider another facility as an alternative, verify that facility’s hours, charges, age rules and tattoo conditions rather than assuming your original booking or admission applies there. (Tenzan; Hakone Yuryo)

Are the prices above a complete trip budget?

No. The facility charges listed here do not include transport, meals, lodging or separately purchased towels. For example, Tenzan’s listed adult admission is ¥1,450 and payment is cash only, while Hakone Yuryo public-bath admission should be added only if you use that area alongside a private room. The Romancecar’s ¥1,200 limited-express charge is also not the full train fare, because a basic fare ticket is required separately. (Tenzan; Hakone Yuryo; Odakyu Romancecar)

Travellers have shared different approaches to Hakone stays and day trips, including Kensho Quest’s introduction to a ryokan stay with a reserved onsen, FREE DAYS’ budget-focused Hakone onsen trip, and Chad and Claire’s ryokan and onsen experience. 우당탕탕 예패밀리 also shares a Korean-language family ryokan trip. These are individual creators’ experiences, not substitutes for checking the current rules, prices and availability of the facility you plan to visit.
