Rates & booking

koti hakone is a private villa for one group per night. Rates are set per house, not per person, so the more of you there are, the less each person pays.

This page covers how rates work, how to book, paid extras, payment and cancellation. The accommodation rate changes depending on your dates, so please check it on the calendar along with availability.

How rates work

Your total is made up of four things:

• Accommodation rate (per house): Varies by date (season and day of the week). Weekdays (especially Tuesday, Wednesday and Thursday) are lower, and Saturdays are higher.
• Additional guest fee: The rate is the same for up to 8 guests. From the 9th guest, it's ¥8,000 per person per night.
• Cleaning fee: ¥33,000, charged once per stay. Whether you stay one night or three, we clean once. The building is large, so the cleaning fee is on the higher side. Thank you for your understanding.
• Paid extras: Optional services such as the sauna or firewood, for those who want them (see the table below).

The accommodation rate includes consumption tax, service charge and accommodation tax. Exclusive use of the whole house, the large hot-spring bath and use of the BBQ grill are also included in the accommodation rate.

The longer you stay, the lower the cleaning fee per night

The cleaning fee is charged only once per stay, so the more nights you stay, the less it costs per night.

For example, 10 guests staying one night pay an additional guest fee for 2 people: ¥16,000.

How we count guests, and capacity

• Children aged 2 and over count as guests, the same as adults.
• Children under 2 who don't use their own bedding stay free, up to 4 children. They are not counted as guests.
• Standard capacity is 21 guests (21 single beds). With futon sets, up to 26 guests can stay.

Booking on our official website is the best price

koti hakone is priced so that booking on our official website (direct booking) is always the cheapest option.

Direct bookings get these discounts:

• Early booking discount: 10% off when you book at least 90 days before your stay.
• Multi-night discount: 10% off for 2 nights, 15% off for 3 nights.

Traffic in Hakone gets very heavy on weekends and public holidays. Staying 2 nights makes it easier to avoid the busiest times, and it lowers the cleaning fee per night.

You can also book through booking sites: Airbnb, Booking.com, Yahoo! Travel (Yahoo!トラベル) and Homes & Villas by Marriott Bonvoy. For those bookings, rates, cancellation policies and receipts follow each site's rules.

How far ahead you can book

We accept bookings up to about 6 months in advance.

Payment methods

• Bookings on our official website: Prepayment by credit card. You register your card when you book, and it is charged 14 days before check-in.
• Corporate bookings: We accept bank transfer against an invoice (for corporate stays, see also Company trips & training). Request a quote or invoice through the document request form (we'll send it as a PDF). Your booking is confirmed once we confirm your transfer. Until the transfer is complete, the booking is not confirmed, so other guests may book the same dates in the meantime.
• Bookings through booking sites: Payment follows each site's methods.

Cancellation policy

For bookings on our official website:

• Bookings through booking sites follow the cancellation policy of each site and plan.
• In the event of typhoons or other disasters, our standard cancellation policy generally still applies. However, if both roads and public transportation are shut down and there is no way to get here, we will refund the full amount you paid.

Changing your guest count or dates

• Fewer guests: As a rule, the cancellation policy applies (see the Terms and Conditions of Accommodation for details).
• More guests: From the 9th guest, it's ¥8,000 per person per night. If you use more bedding than the number of guests you booked for, we charge ¥8,000 per bedding set. If your group grows, please pay the additional amount using the payment link in the Stay Guide and let us know. Airbnb bookings can change the guest count on the site.
• Changing dates: Airbnb bookings can send a change request. For all other bookings, please cancel and book again (the cancellation policy applies).

We recommend cancellation insurance

Cancellations from 14 days before your stay cost 100% of the accommodation rate. To be covered for things like sudden illness, we recommend taking out cancellation insurance. We especially recommend it for trips with children.

• When you can apply: 9–14 days before your stay
• Typical premium: about 2.5% of the trip cost

The one we recommend is Mysurance's "Domestic Travel Cancellation Insurance" (国内旅行キャンセル保険).

We also explain how to choose a policy in our Owner's Blog post "Traveling with little kids? Travel cancellation insurance you'll definitely want" (in Japanese).
