About Tenzan Toji-kyo
Tenzan Toji-kyo, Japan is a day-use hot spring facility in the Okuyumoto area of Hakone, Hakone-machi, Ashigarashimo-gun, Kanagawa Prefecture. It is part of the Tenzan Hot Springs Resort, a complex of four buildings in a forested mountain valley: the main Tenzan facility, Higana Toji Tenzan, Kayoi Onsen Yuya Ikkyu, and the overnight ryokan Hagoromo. The main Tenzan building is the principal day-use facility, offering multiple outdoor rotenburo and indoor baths without advance reservation.
The facility uses two spring types. The first is a chloride spring noted for warming the body and relieving stiff shoulders. The second is an alkaline simple spring with skin-softening properties that has been approved for drinking. Indoor baths are constructed from lacquer-coated hinoki cypress. The outdoor baths are set among trees and vines and include a large hot bath, a multi-level bath, a cave bath, a cedar bath, and a milky-coloured pool. Facilities also include a sauna dome, a covered bathing area opening to the mountainside, shampoo, conditioner and Tenzan's own soap, tatami rest areas, restaurant Yamaboshi serving nourishing mountain cuisine including eel and regional dishes, and a cafe. Tattoos are permitted.
Location & Access
Getting to Tenzan Toji-kyo
Tenzan Toji-kyo is at 208 Yumoto Chaya, Hakone-machi, Ashigarashimo-gun, Kanagawa Prefecture, in the Okuyumoto area approximately 25 minutes on foot or a short bus ride from Hakone-Yumoto Station. From Hakone-Yumoto Station (Hakone Tozan Railway), take the Hakone Kyukaido Line bus and get off at the Oku-Yumoto Entrance bus stop, then walk for approximately 2 minutes. The bus journey takes around 5 minutes. Alternatively, the facility is approximately a 25-minute uphill walk from Hakone-Yumoto Station. From central Tokyo, take the Romancecar limited express from Shinjuku to Hakone-Yumoto Station, approximately 80 minutes, then the bus or walk to the facility.
No advance reservation is required for day use. Entry tickets are purchased at a vending machine outside the main entrance before entering the building. Adult admission is 1,450 yen (1,350 yen with the Hakone Free Pass). Children are 700 yen. Shampoo, conditioner and body wash are provided at the bathing facilities. Towels can be purchased if needed. The facility includes a restaurant, cafe, and rest areas which can be used without an additional charge after bathing. Free parking is available at the facility for visitors arriving by car.
Suitability & Accessibility
Who Tenzan Toji-kyo Suits
Tenzan Toji-kyo suits visitors to Hakone who want a full-featured day onsen experience with multiple bath types, a relaxed non-rush atmosphere, and the ability to spend several hours dining and resting after bathing. The combination of outdoor woodland baths, a milky alkaline pool, a cave bath, tatami rest areas, and a restaurant serving nourishing mountain cuisine makes it more comprehensive than a simple public bathhouse and popular as a half-day or full-day stop from Tokyo.
Tattoos are explicitly permitted, making it one of Hakone's more internationally accessible onsen facilities. The facility is also popular with Hakone Free Pass holders, who receive a discounted entry. The two different spring types allow visitors to compare a skin-softening alkaline spring against a warming chloride spring within the same visit. No advance booking is needed, which suits spontaneous day trips from Tokyo or Yokohama.
Families are welcome; children are admitted at 700 yen. Wheelchair accessibility is not specifically documented for the outdoor bath areas; the facility involves uneven outdoor paths among trees. The toji concept at the broader Tenzan complex allows for longer therapeutic stays at the adjacent ryokan Hagoromo if a multi-day bathing experience is desired. Hakone-Yumoto has restaurants and shops around the station area for visitors who want to combine the onsen with a wider Hakone day trip.
Safety & Etiquette
Tenzan Toji-kyo Safety Tips
Tenzan Toji-kyo is generally safe as a well-managed day-use facility with showers, multiple pools, and staff on site. The main safety considerations are the variety of pool temperatures and the outdoor nature of most baths.
The outdoor baths vary significantly in temperature; the large main pool is described by visitors as very hot. Start with the mildest pool, the milky-coloured alkaline bath, and work progressively toward hotter baths rather than entering the hottest pool first. A cold-plunge rock pool is available for cooling down between soaks. Limit time in any single hot pool to 10 to 15 minutes and rest in the seating areas between soaks, drinking water throughout. People with heart conditions, hypertension, or open wounds should consult a doctor before bathing. Wash thoroughly at the showers using the provided soap before entering any bath. Do not bring the small towel into the bath water; fold it and rest it on your head or on a nearby ledge as is customary at Japanese onsen.
The outdoor paths between the baths are set among trees and vines and can be wet and slippery; move carefully and use provided handrails. The cave bath and multi-level pools involve steps; take care when entering and exiting. In winter the transition between the hot pools and the cold mountain air can be intense; wrap up quickly after exiting a bath. The alkaline spring is approved for drinking at the designated drinking area; do not drink from the baths. Photography is not permitted inside the bathing areas.
