Hakone Yunessun tickets: price by date, Passport vs Mori no Yu, tattoo rules (calculator)

Short answer: Hakone Kowakien Yunessun is a hot spring park where you wear a swimsuit (wine bath, coffee bath, slides), and Mori no Yu next door is a regular naked hot spring. The door price depends on the day. On an A day (most weekdays) an adult pays ¥2,500 for Yunessun, ¥1,500 for Mori no Yu, or ¥3,500 for the Passport to both. On a B day (weekends, holidays, New Year and late March) it is ¥2,800 / ¥1,700 / ¥3,700, and on a C day ¥3,000 / ¥1,800 / ¥4,000. Children aged 3 to elementary school pay from ¥1,000; under 3 free. Towels and swimsuits cost extra. Tattoos must be covered. From Shinjuku: Romancecar to Hakone-Yumoto, then about 20 minutes by bus to the Kowakien stop.

Ticket prices by day type

• Adult = junior high school age and up. Child = age 3 to elementary school. Age 0–2: free.
• Discount (シルバー・障碍者割引): age 65 and over (bring ID with your age), or a disability certificate holder plus up to 2 companions. Discounts cannot be combined with other coupons.
• Passport = both areas on the same day. It costs ¥500 less than two tickets on an A day and ¥800 less on B and C days, per adult.
• The ticket is entry only: no time limit, and you can go out and come back the same day after a re-entry procedure at the front desk.
• Advance web tickets on the official ticket page are cheaper than the door price: a One Day Pass, an Afternoon Pass (enter from 13:00; not on C days) and a Sunset Pass (enter from 15:00). The price shows when you pick a date. Bring the ticket to the front desk; it does not open the gate by itself.

Which days are A, B or C?

Yunessun sets the price class day by day. On the official calendars for October 2026 to March 2027, Saturdays and Sundays are B and the other days are A, with the extra B days and closed days below. No C days are marked in this period (C days are usually the busiest holidays, such as summer).

Later months: check the price calendar on the official price page (A日程 = A, B日程 = B, C日程 = C).

Opening hours

• Yunessun (swimsuit area): 10:00-18:00, last entry 17:00 on weekdays; 9:00-19:00, last entry 18:00 (Saturdays, Sundays, holidays).
• Mori no Yu (hot spring): 11:00-20:00, last entry 19:30, every day.
• Last entry is 1 hour before closing at Yunessun. Hours can be extended in some seasons and can change without notice.

Tattoos at Yunessun and Mori no Yu

• The official rule: guests with tattoos (including stickers and paint) are refused in principle.
• Yunessun (swimsuit area): OK if you cover the tattoo, for example with a rash guard. Rash guards can be rented (paid).
• Mori no Yu (naked hot spring): only if 2 of Yunessun's own tattoo cover seals (paid) cover it completely. If they cannot, book a private bath (8 rooms, reservation online only).
• Hakone has hot springs with no tattoo restriction; see our Hakone day-use onsen guide.

What to bring, rentals and fees

• You can bring your own towels and swimsuit. Shampoo and soap are provided in the Yunessun showers and the Mori no Yu washing area.
• No sandals and no leisure mats in the swimsuit area.
• Children still in diapers wear swim diapers under the swimsuit in Yunessun. Mori no Yu's baths are not for them: use the washing area or a private bath.

Getting there from Tokyo

1. Shinjuku → Hakone-Yumoto: Odakyu Romancecar, about 90 minutes. Fares and seats: Romancecar tickets guide.
2. Hakone-Yumoto → Kowakien (小涌園) stop: Hakone Tozan Bus or Izuhakone Bus, about 20 minutes. Yunessun is across the road from the stop.
3. From Tokyo Station: Shinkansen Kodama to Odawara (about 35 minutes), then bus to Kowakien (about 40 minutes).

The Hakone Freepass covers Hakone Tozan Bus rides, including the bus to Kowakien, but not the entry ticket. Check whether the pass pays off with the Hakone Freepass calculator. We could not read the single bus fare from the official route search when we checked, so it is not in the calculator.

Hako Ticket or the door price?

The Hako Ticket (¥5,500 per adult for 1 day, ¥2,000 per child) includes both Yunessun and Mori no Yu and 18 other Hakone places. For Yunessun alone it costs more than the Passport (¥3,500–¥4,000). It pays off if you add museums or another hot spring the same day: try the Hako Ticket calculator.
