- The upper level of each built-in closet is a built-in closet bed, a semi-single about 170 cm long, where children and smaller adults can sleep
- For 22 or more guests, we use the spare futon sets (5 sets)
- If you have a lot of luggage, you can leave it in the cloakroom on the first floor (1F). It's next to the 1F restroom, across from the laundry room
- Because the beds are low, we don't provide cribs

20 people around one table
The big table in the center of the 1F living room is the heart of koti hakone. It seats 16 as is, and when you extend it by adding the corner side table in between, 20 people can sit around one continuous table.
For more than 20, you can add seats by gathering the 4 kids' chairs from the storage room under the stairs and the round stools around the house (about 8). Unlike a restaurant, your group isn't split across tables, so whether it's a three-generation family trip or a company trip, everyone can join the same conversation.
4 kids' high chairs
If you change the layout, we'd appreciate it if you could put everything back in its original place before check-out.

Meals for a large group
- Cooking for yourselves: The commercial-grade kitchen has a 3-burner induction cooktop, a large dishwasher, a 10-cup (10-go) rice cooker, a microwave oven and a hot plate. There are plates, glasses and cutlery for 20, plus 10 children's sets
- Private chef: We can introduce 3 recommended private chefs (who cook at the house). Most require 6 or more guests and start from ¥8,000 per person (plus the chef's travel costs), and some can do the grocery shopping for you
- BBQ: The covered BBQ area (under the building) has 2 gas grills. You can also use an ingredient delivery service (BBQ Wakita (BBQワキタ); order at least 5 days ahead; from ¥3,000 per serving, minimum 8 servings)
- Groceries: The nearest store, A-Coop Sengokuhara (エーコープ仙石原店), is small and closes at 6:00 pm, so if you're driving we recommend supermarkets in Odawara (小田原) or Gotemba (御殿場). Delivery from AEON Net Super (イオンネットスーパー; order at least 1 week ahead) is also available
- Breakfast: We sell breakfast bread sets and frozen pasta and risotto at the house

Good to know before a large-group stay

- All bedrooms are on 2F, and there is no elevator
- This is a quiet vacation-home area, so outdoor areas can't be used after 9:00 pm. In the evening, please close the windows and stay indoors

Is there an extra charge if more people join us?
The rate is the same for up to 8 guests; from the 9th guest, there's an additional ¥8,000 per person per night. If your group grows after you book, please let us know in advance through our LINE official account. If more bedding is used than the number of guests booked, we charge ¥8,000 per bedding set. Airbnb only lets you select up to 16 guests on its booking screen, so for groups of 17 or more, please tell us the exact number after booking. If your group gets smaller, our cancellation policy generally applies.
How many guests can stay?
The house normally sleeps 21 (21 single beds), and up to 26 using futons. However, with more than 21 guests, the stay may be less comfortable. Children under 2 who don't use their own bedding (up to 4) aren't counted in the number of guests. Airbnb only lets you select up to 16 guests on its booking screen, so for groups of 17 or more, please tell us the exact number after booking.
Can we park a bus?
Vehicles up to a microbus can enter the parking lot on the property (one microbus at most). Medium-sized and larger buses can't drive on the roads in the villa area.
How late can we stay up at night?
There's no time limit indoors. Because we're in a quiet villa area, the outdoor spaces (the garden, outdoor kids' park, BBQ area, fire pit and sauna) can't be used after 9:00 pm, even quietly (the smoking area may be used quietly). After 9:00 pm, please close the windows and stay indoors, and please refrain from playing the piano.
Can multiple families have separate rooms?
With 5 bedrooms and the playroom, you can split up into as many as 6 separate sleeping areas. The kids' room on the first floor (1F) is behind the kitchen, so children can play while the adults relax in the living and dining room.
