Kasuitei Ooya is a ryokan on the shore of Lake Kawaguchi, in Fujikawaguchiko, Yamanashi. It was founded in 1923 and has 46 rooms around an inner garden. Before you book, three things matter: the open-air baths in its guest rooms use Mt Fuji water, not hot spring water; the 7th-floor private bath is booked by phone only; and the shared bath hours differ between official pages, so confirm them with the inn.

Getting to Kasuitei Ooya from Kawaguchiko Station
How do I get there from Tokyo?
By rail, change from the Chuo Line to the Fujikyu Line at Otsuki for Kawaguchiko Station, a ride the inn lists as 55 minutes. Highway buses run from Busta Shinjuku to Kawaguchiko Station. From the station, the inn is about 10 minutes on foot or 5 minutes by car. By car, it is about 15 minutes from Kawaguchiko IC on the Chuo Expressway; the inn has parking, but the official pages do not give a fee or the number of spaces.
Is there a pickup from the station?
Yes. The inn runs a pickup from 14:00 to 19:00 and from 8:00 to 10:00. Call the inn when you arrive at Kawaguchiko Station. For ideas nearby, see our things to do at Lake Kawaguchi. From October to December 2026, the home page also lists a bus to Hakone at 9,000 yen per person on set weekdays.
Rooms at Kasuitei Ooya: which view do you get?
The inn lists nine room types in the main buildings. The view matters more than the name, because some rooms face the lake, some face Mt Fuji across the town, and some face inward with no view.
| Room type | View | Bath and toilet | Guests |
|---|---|---|---|
| Japanese room with cypress open-air bath (top floor) | Lake | Open-air bath, toilet | Up to 6 |
| Japanese room with Shigaraki-ware open-air bath | Lake | Open-air bath (one-person tub), toilet | Up to 6 |
| Modern Japanese-Western room, lake side | Lake | Shower booth, toilet | Up to 6 |
| Japanese room, lake side (main building) | Lake | Bath, toilet | Up to 5 |
| Japanese room, Mt Fuji side (new building) | Mt Fuji across the town, weather permitting | Bath, toilet | Up to 5 |
| Japanese room, inner side | No view | Bath, toilet | Up to 5 |
| Japanese room without bath, inner side | No view | Toilet only | Up to 2 |
Selected types from the official rooms page, read October 16, 2026. Sizes are left out because the Japanese and English pages give figures that do not match.
Can I choose a lake view?
Book a lake-side room type. The booking page adds that, depending on bookings, the view may not match your request, and asks you to confirm by phone at 0555-72-1212.
What is the annex?
Opened in May 2023, the annex is a separate building one minute’s walk away with self-catering condominium rooms and open-air baths; no meals are served. A second annex, Nagisa, is in the building next door. On the booking page, the condominium starts at 88,000 yen per room and Nagisa at 150,000 yen per room.
Meals at Kasuitei Ooya
What is dinner like?
Dinner is kaiseki. The signature dish is the inn’s hand-made hoto noodle hot pot in its own miso soup, and rice is cooked with ancient-grain rice grown at Lake Kawaguchi. For groups of 2 to 4, dinner is served in your room; groups of 5 or more eat in a private dining room. On the standard plan, dinner starts between 18:00 and 18:30, and you cannot choose where you eat.
When is breakfast?
Breakfast starts between 7:30 and 8:30 in the banquet hall. The official pages do not say whether it is set meals or a buffet.
Can the inn handle allergies?
For children, the FAQ states plainly that the inn cannot accommodate allergies. For adults, allergies and vegetarian or other diets are not covered on the official pages, so email or call before you book.
The baths at Kasuitei Ooya
What baths are there?
The shared baths use Fujikawaguchiko Onsen water, a calcium-sodium sulfate-chloride spring. On the 7th floor are two view baths with open-air tubs, and in the basement are two large baths with a sauna, an open-air bath and a cascade bath. The open-air baths in the guest rooms are different: they use Mt Fuji water, which the inn says it chose so that guests who must avoid hot spring minerals can bathe safely.
When are the baths open?
This is the point to confirm. The hot spring page gives evening and early-morning hours for the shared baths, but the FAQ lists different hours for the basement baths, and the private bath has different hours on three official pages. Ask the inn at check-in for the hours on your night.
How does the private bath work?
The 7th-floor private bath, Ukifune, costs 3,300 yen for 50 minutes. The booking page says reservations are taken by phone only. The elevator stops at the 6th floor, so you take the stairs for the last floor.
Can I bathe with a tattoo?
The official pages do not mention tattoos. Ask the inn before you book; a room with its own open-air bath is one option to raise. Our tattoo and onsen guide explains what to ask.
Prices, children, cancellation and payment at Kasuitei Ooya
How much does a stay cost?
Per person, sharing a room for two, the official booking page starts at 16,300 yen room only in an 8-mat room without a bath or view, 19,400 yen room only in a 10-mat room, 24,200 yen on the standard plan with dinner and breakfast, and 36,300 yen with two meals in a room with a cypress open-air bath. Prices include tax; the bathing tax of 150 yen per adult is extra (see our onsen bathing tax guide). The town also plans a lodging tax of 200 yen per person per night from April 1, 2027, according to the Fujikawaguchiko town site.
What do children cost?
Elementary school children pay 70 percent of the adult rate, and infants with meals and bedding pay 50 percent. Infants under one stay at no charge. Lower flat rates apply to infants with only meals, only bedding, or neither; the official pages give different amounts for these, so confirm with the inn. Infants do not count as guests online, so one adult with only preschool children cannot book on the web.
What is the cancellation policy?
The standard rule is 20 percent from 7 to 4 days before, 30 percent at 3 to 2 days, 50 percent the day before, and 100 percent on the day or for a no-show. A plan’s own rule takes priority, so check it on the booking page. Our hotel cancellation guide covers how these fees work.
How do I pay?
Online bookings are paid by card online only, with no deposit. At the inn, the listed cards are JCB, Visa, Mastercard, American Express, UC, DC, NICOS, Diners, Saison and UFJ.
