Tenzan Tojikyo

What to expect

Tenzan Tojikyo is a day-bathing complex in Oku-Yumoto, the wooded upper end of Hakone-Yumoto, about 10 minutes by shuttle bus above the station. The name roughly means “Tenzan hot spring cure village”, and it is built around that idea: you come for half a day or a whole day, bathe, rest, eat, bathe again. There are no rooms in the main complex, no swimsuit zones and no amusements. The operator says plainly that it is not a leisure facility.

The grounds include two separate bathhouses and several places to eat and rest:

• Higana Toji Tenzan (“Tenzan” for short), the main bathhouse, where most visitors go.
• Kayoi Toji Ikkyu, a simpler sister bath for people who only want to soak.
• Hanare-gumo, seven private rest rooms rented by the hour.
• Two restaurants, a café, a body-care salon, a shop and a lounge by the Sukumo River.

The baths

The main bath at Tenzan has separate men’s and women’s sides, each with an indoor bath and outdoor rock baths. The men’s side has a kama-buro, a stone kiln-style steam sauna, and the women’s side has a steam bath using spring steam and a dry sauna. Shampoo, rinse, soap and hair dryers are provided.

Ikkyu is plainer. Each side has an indoor and an outdoor bath, with soap and a hair dryer but no shampoo, rinse or showers. The men’s and women’s sides have different views.

You bathe naked. Bring a small towel (the operator suggests about 34 x 85 cm) for washing and for drying off before you go back to the changing room, plus a bath towel for the changing room, or buy them at the desk.

The water

Tenzan draws on seven sources of its own, on the site or close by, with a combined flow of about 347 litres a minute, roughly 500 tonnes a day. The operator lists two spring types:

• Alkaline simple spring, pH 9.3, from a blend of sources No. 92, 93, 101, 102 and 114 and from Yumoto No. 74. No. 74 holds a drinking permit, which the operator says is the only one in Hakone, and it is very soft, with almost no magnesium and about 1.2 mg of calcium per litre.
• Sodium chloride spring from Yumoto No. 115.

The sources run up to 181°F83°C. Rather than adding cold water, Tenzan cools the water through a heat exchanger and keeps each bath within a narrow temperature range. It says the water goes straight to the baths without being stored, and every bath is drained and refilled each night. The Hakone tourism association describes the baths as free-flowing. Bath temperatures are not published.

Prices and booking

Prices are from the operator in October 2026.

What	Adults	Children (1 to elementary)
Tenzan	¥1,450	¥700
Ikkyu	¥1,200	¥700
Weekday combined ticket, Tenzan then Ikkyu	+¥300	+¥200

The combined “hashigo-yu” ticket is sold on weekdays only. Ikkyu runs 11:00-20:00 on weekdays and 11:00-21:00 on weekends and holidays (last entry an hour before), and closes on Thursdays.

Hanare-gumo private rooms cost ¥4,500 for two hours for up to three people, plus ¥1,800 for each extra hour, or ¥4,200 for four hours for one person (rates from August 1, 2025). They run 10:00-18:00 with last reception at 16:00, and cannot be booked. Room guests can use the small Oku-no-yu bath, which is still separated by sex and closed to tattooed guests and to children of elementary age or younger.

There is no booking for bathing or for the restaurants, and groups of more than six adults, tour groups and agent-led visits are turned away. Payment is cash only for most things, and there are no ATMs nearby. A yukata rents for ¥500. You need an admission ticket even if you only want to eat. The Sanposhi restaurant closes Wednesdays and Thursdays, and the Rakuten shabu-shabu restaurant closes Mondays, Tuesdays and Fridays.

Getting there

Tenzan is at 208 Yumoto-chaya, Hakone, on the old Hakone road above Hakone-Yumoto.

• Ryokan shuttle: from the rotary in front of Hakone-Yumoto Station, take the B course (Sounkan-dori line) and tell the driver “Tenzan”. About 10 minutes, ¥200 for adults, ¥100 for elementary children, preschoolers free. Bring the exact fare. There are no departures from the station in the 11:00 and 12:00 hours.
• Route bus: Hakone Tozan bus, K line (Hakone Kyu-kaido), from stop 4 at Hakone-Yumoto Station to Oku-Yumoto Iriguchi, ¥260, then about a 5-minute walk.
• By car: about 10 minutes from Yamazaki IC on the Odawara-Atsugi Road, or 45 minutes from Gotemba IC on the Tomei Expressway. Parking is free, about 140 spaces, and entry can be restricted when the lot is full.

The operator warns that taxis are scarce in Hakone and late buses are limited, especially toward Moto-Hakone and Lake Ashi, so plan the ride back before you settle in for a long soak.

When to go

Tenzan is open every day except a short maintenance break in mid-December. Weekends, holidays and the Golden Week, Obon and Silver Week periods are the busiest, and the operator posts special hours for them. A weekday morning soon after opening is the calmest time. Late May to early June brings fireflies to part of the grounds.

Where to stay nearby

The main complex has no rooms. A third facility, Toro Toji Hagoromo, takes guests for stays of three nights or more. Most visitors stay in Hakone-Yumoto, which has the largest choice of inns and hotels close by. Two other day-bathing options on this site are Hakone Yuryo, near Hakone-Yumoto Station with private open-air rooms, and Hakone Kowakien Yunessun, a swimsuit spa park up the mountain at Kowakudani.

Safety notes

• Heat: the operator warns against hot baths and long soaks on an empty stomach. Keep soaks short and drink water.
• Footing: stone paths and outdoor rock baths get slippery, especially in rain.
• Children: the water is set for adults, so ease small children in slowly or keep them to short dips.
• Pregnancy: the operator leaves the decision to you, and asks people prone to anaemia or fainting to take extra care.
