Kawaguchiko Onsen

What to expect

Kawaguchiko Onsen is the hot spring resort on the shore of Lake Kawaguchi, one of the Fuji Five Lakes and the one with the longest shoreline, in Fujikawaguchiko town, Yamanashi Prefecture. It is new by Japanese standards. The local area guide, set up with Japan Tourism Agency funding, says it opened in 1992 (Heisei 4) and draws on four sources: Reiho no Yu, Tensui no Yu, Reisui no Yu and Fuyo no Yu. Deep drilling made it possible; Fuji Lake Hotel, for example, says its water comes from 1,500 m underground.

So do not expect an old bathhouse district with wooden buildings and yukata crowds. Kawaguchiko Onsen is a scatter of resort hotels, ryokan and small guesthouses along the lake. What sets it apart is the view. On a clear day many open-air baths look straight across the water to Mount Fuji, and that is what people book.

The water itself is not the main talking point. Hotels here sell the setting rather than a famous mineral profile.

Where to bathe

Hotel and ryokan baths

Most of the soaking at Kawaguchiko Onsen happens in hotel baths, either as a guest or on a day visit. The area guide says many of the inns welcome day bathers as well as overnight guests, but policies, prices and hours vary hotel by hotel and change often, so check directly.

Fuji Lake Hotel is a good example of what to expect. Founded in 1932 on the Funatsu shore, it has gender-split large baths with open-air tubs (a cypress tub and a rock bath), a sauna and jet bath, and private baths you can reserve, including a step-free lake-view private bath with a bath lift. Its large-bath hours were listed in October 2026 as 14:00 to 24:00 and 5:00 to 10:00 (shortened hours). It is about 10 minutes on foot from Kawaguchiko Station.

Fuji Chobo no Yu Yurari

The biggest stand-alone day bath nearby is just over the line in Narusawa village, about 10 minutes by car from Kawaguchiko IC. The town tourism federation lists it with two open-air baths facing Mount Fuji and 16 kinds of bath in total, including a carbonated bath and a cave bath. Its operator describes the water as rising from a fault zone 1,500 m down.

• Hours: weekdays 10:00 to 21:00 (last entry 20:00); weekends and holidays 10:00 to 22:00 (last entry 21:00). Open every day.
• Adults: ¥1,400 weekdays, ¥1,700 weekends and holidays, before 19:00. After 19:00, ¥1,200 and ¥1,500.
• Children (age 4 to elementary school): ¥750 weekdays, ¥800 weekends.
• Spring, summer, Golden Week, New Year and public holidays are charged at weekend rates. A bath towel and face towel are included.
• Tattoos: refused, along with anyone visibly drunk.
• Getting there: free shuttle bus from Kawaguchiko Station, about 20 minutes, booked online in advance. 130 free parking spaces.

The private baths at Yurari are reserved for guests of the neighbouring Fuji Midori no Kyukamura lodge.

Takano Yuri Spa and Hotel Ouan

In the Katsuyama district of the town, this adults-oriented spa hotel sells day use of its baths and saunas from 8:00 to 22:00 (last entry 21:00), with no fixed closing day. The town federation lists a carbonated bath, a jet bath, a weekly-changing bath, and lava, barrel and salt saunas. Children of elementary age and under are not admitted. A shuttle bus runs every two hours from stop 10 at Kawaguchiko Station.

Kaiun no Yu

The town’s tourism federation also lists a day bath called Kaiun no Yu in Funatsu, but gives no hours or prices. Contact it directly before planning around it.

Onsen etiquette

• Wash thoroughly at the taps before getting into a shared bath.
• Bathe naked in the gender-split baths. No swimsuits, and towels stay out of the water.
• Tie up long hair.
• No photos in changing rooms or baths, even if Mount Fuji looks perfect. Many hotels have a viewing deck or private bath for that.

Tattoo rules vary. Yurari refuses tattooed guests outright. Most hotels do not publish a policy, so ask when booking, or reserve a private bath or a room with its own open-air tub.

Getting there

Kawaguchiko Station on the Fujikyu Railway is the hub. Trains run there via Otsuki, and the station is also the main stop for highway buses from Tokyo. Some hotels run free shuttles from the station; Fuji Lake Hotel, for one, will pick you up if you phone on arrival.

By car, the Chuo Expressway Fujiyoshida Line ends at Kawaguchiko IC, about 10 minutes from the main day baths. Yurari has 130 free spaces; hotels generally have their own parking.

When to go

Kawaguchiko Onsen is open all year. Mount Fuji is the variable. It often hides in cloud, and your best odds of a clear view are usually on cold, dry mornings in late autumn and winter. Autumn leaf season and spring blossom bring the biggest crowds.

Weekends, Golden Week, Obon and the New Year holidays are expensive and busy. Midweek stays cost less, and the hotel baths are calmer.

Where to stay nearby

There is no shortage of rooms: the town tourism federation’s lodging list runs from luxury villa hotels with in-room hot spring baths to campgrounds. Rooms with a lake and Fuji view cost more and sell first.

Lodging tax: from April 1, 2027, Fujikawaguchiko town charges a flat ¥200 per person per night at all lodgings in town, regardless of the room rate or the guest’s age. Children paying a child rate are taxed; infants who stay free are not. The town’s tax office (0555-72-1113) handles questions.

Safety notes

• Hot and cold: winter nights by the lake drop well below freezing. Moving between a hot tub and freezing air is hard on the heart, so take your time and keep soaks short.
• Alcohol: do not bathe after drinking.
• Footing: outdoor bath decks ice over in winter.
• Dehydration: long soaks in hot water leave some visitors light-headed. Drink water between baths.
