Konansou is a 50-room hot-spring ryokan on the south shore of Lake Kawaguchiko, ten minutes on foot from the station, with Mt. Fuji in the window from one side of the building and the lake from the other. It is the kind of place people book for the picture and then trip over the rules: check in by 18:00 or dinner is gone, unpaid back; checkout at 10:00; a child of two pays 3,300 yen; the private Fuji-view bath is 3,300 yen per 50 minutes; and cancellation fees begin a week out.
Everything below is from the official English site: the hotel policy, the Q&A, and the cuisine, facilities, access and news pages. Room rates are not here; the child, bath and a la carte prices the ryokan publishes are.

What is Konansou in Kawaguchiko, and which side should I book?
A family-run ryokan in the Fuji-Kawaguchiko hot-spring village of Funatsu, built up over the years into 50 rooms: 43 Japanese-style and 7 Japanese-Western, all with a bathroom and washlet, of which 13 have a private open-air bath, five are “special rooms” on hot spring water and six have a view bath. The building has two faces. The Mt. Fuji side has ten rooms, every one with an open-air bath, sleeping up to four. The lake side has 40 rooms sleeping up to six. The site’s own itinerary shows the idea: shuttle from the station, bath before dinner, dinner in the room at 18:45, a room bath or the big bath at 22:00, breakfast at 7:15 and the rooftop footbath at 8:48 to plan the day.
What is on the roof?
A natural hot-spring footbath called Foot Spa Waku Waku, with free telescopes pointed at Fuji and the lake, open to guests at no charge except between 21:00 and 7:00. It is the ryokan’s signature and the place to check the mountain before you commit the morning to the lake’s sights.
What else is in the building?
A karaoke party room and a table-tennis corner, 15:00 to 22:00; a souvenir shop, 7:00 to 21:00; a free microwave and ice machine on the 3rd floor; soft-drink vending on the 4th; free Wi-Fi in every room; and a convenience store three doors down. There are no accessible rooms and wheelchairs cannot be used inside guest rooms, which the Q&A states plainly.
Check in by 18:00: the dinner rule
What are the hours?
Check-in 15:00 to 19:00, checkout 10:00. The 19:00 limit exists so the kitchen can time dinner; if you will be later, the ryokan asks for a call.
What happens if I am late with a dinner plan?
The policy is unusually blunt: guests whose reservation includes dinner must complete check-in by 18:00, and “if you check in later than this, dinner will be canceled without refund”. A late express bus from Shinjuku or a long queue at Fuji-Q can cost you the kaiseki you paid for. Build the afternoon around 18:00, not the other way round.
Can I add dinner later?
Not on the day. A breakfast-only booking cannot have dinner bolted on; you rebook onto a half-board plan. Adding a child’s dinner to a dinner plan needs an inquiry and reservation in advance, and a children’s plate must be ordered by 18:00.
Cancellation: fees start seven days out
| When you cancel | Fee |
|---|---|
| 8 days before or earlier | None |
| 7 to 4 days before | 20% |
| 3 to 2 days before | 30% |
| Day before | 50% |
| Arrival day / no-show | 100% |
Official Q&A, read September 16, 2026. Six or more rooms: different conditions.
How do I pay?
Online bookings are settled by credit card in full at the time of booking, at the rate of your checkout date, and the charge appears as SB Payment Service Corp.; a cancellation fee is taken from it. At the desk the ryokan takes Visa, Mastercard, JCB, American Express, Diners, UC, Saison, Nicos, DC and UnionPay. Adding a guest is possible until the day before, subject to the room’s capacity, and changes the per-person rate.
How does this compare with a hotel chain?
Chains like Vessel Hotels charge nothing until a few days out; a ryokan that buys fish for a fixed number of kaiseki dinners starts earlier. Seven days is typical for the ryokan category, and the 100 percent on the day is universal.
Children: free under one, 3,300 yen from two
| Child | Rule (official policy) |
|---|---|
| Under 1, in parents’ bed | Free |
| Ages 2 to 6, in parents’ bed | 3,300 yen a night, breakfast buffet included |
| Age 13 and up | Adult |
| Children’s dinner | Elementary age: reduced adult kaiseki. Preschool: children’s plate 1,320 yen, order by 18:00. Book in advance. |
| Equipment | Children’s yukata in several sizes, baby bath and baby shampoo in the large bath. |
| Extra beds | Only in room types that list them. |
Official Konansou child rules, read September 16, 2026. The policy does not state a rate for ages 7 to 12 sharing a bed; ask when booking.
What does a child eat?
The cuisine page lists a children’s plate of lightly seasoned rice, flaked sea bream and vegetables for preschoolers, and a baby menu; elementary-school children get the adult course minus a few dishes. The ryokan asks you to say so at booking, because dinners are counted, and it cannot cater for a child with a serious allergy.
Dinner in the room, breakfast at the buffet
How does in-room dining work?
It is the house tradition, heya-shoku: a kaiseki course carried to your room by an attendant at a start time you pick between 18:00 and 19:30 (the cuisine page opens the window at 17:30). It is offered for up to four people on one booking; five or more, or anyone who wants a table and chairs, eat in a private room in the banquet hall. Two bookings that want to eat together must say so in the request field, or the ryokan does not promise to seat them together. Whether you eat in the room or a private room is the ryokan’s call, not the guest’s, except for health reasons.
What can I add?
A la carte is for dinner-plan guests only, ordered on the day between 17:45 and 19:30: wagyu shabu-shabu 10,000 yen, beef steak on lava rock 4,840 yen, grilled spiny lobster for two 8,800 yen, Koshu horse sashimi 2,200 yen, chicken-giblet stew 2,000 yen, a seasonal fruit plate 6,000 yen; some items need advance booking. Preference-based changes to the set course are not offered.
What about breakfast?
A buffet at Moegi on the 3rd floor, 7:15 to 9:30 with last entry at 9:00, served even to guests who booked without dinner. The Q&A confirms a stay without dinner is possible but breakfast is always included.
The baths: room onsen, a private bath and the footbath
Which rooms have hot-spring water?
Room types A to E and G to K, plus the open-air-bath rooms Rin and Kohaku. The large public baths have open-air sections and saunas and run on the same spring; the rooftop footbath too. Every room has its own ordinary bath as well.
How do I book the private Fuji-view bath?
At the front desk on the day, for 3,300 yen per 50-minute slot, in slots starting on the hour between 15:00 and 23:00 and 7:00 and 9:00. It faces the mountain. Day visitors are not admitted to any bath.
Are tattoos allowed?
The site does not say, in either the policy or the Q&A. A room with its own open-air bath sidesteps the question; for the public bath, ask before you book. Our tattoos and onsen guide has the general picture.
Getting there, luggage and the closures
How do I get from the station?
Walk ten minutes, or phone from Kawaguchiko Station and the free shuttle collects you at bus stop 10 between 14:00 and 19:30; in the morning it runs you back at a time you set with the desk. Express buses from Shinjuku and the Fujikyu train both end at the same station. Drivers use the prefectural lot across the road, 40 spaces, free.
Can I send luggage ahead?
Yes, with the stay date and booking name on the label, and the desk also holds bags before check-in. Our luggage forwarding guide explains the counters. Pets are not accepted; the ryokan will point you to a pet hotel nearby.
When is it closed?
From 11:00 on December 7 to December 11, 2026, and from 11:00 on January 25 to January 27, 2027, with the phone unanswered during both. Smoking is banned in every room and charged as a cleaning fee if detected.
What is nearby?
The access page lists the Fuji Shibazakura moss-phlox festival at Lake Motosuko from late April to late May, Fuji-Q Highland with its coasters and a summer pool, a herb garden with workshops, the Kawaguchiko autumn-leaves festival, and the Mt. Fuji Marathon, and the desk hands out discount coupons for some of them. Phone hours for the ryokan itself are 10:00 to 20:00.
Is there anything for a rainy evening?
A karaoke party room and table tennis, both 15:00 to 22:00, a shop until 21:00, and the baths. The Q&A also notes a sightseeing brochure at the desk; for a full day around the lake, see our Kawaguchiko guide linked above.
Who Konansou is for
Couples and families who want Mt. Fuji from a private bath and dinner brought to the room, and who can be at the desk by 18:00. It is a poor fit for vegans, for anyone with a serious food allergy, for wheelchair users, and for travelers whose plans may change inside a week.
