10 Private Villas & Glamping Stays for Groups of 15+ (2026 Edition)
A club training camp, a three-generation gathering, a company offsite: once the group tops 15, the choice of stays narrows sharply, and it comes down to splitting rooms or renting the whole place. This article introduces ten whole-rental villas and glamping stays from across Japan where 15 or more can stay together, ranked by popularity on TOMARIBI (泊まり火). It is a list for those who want everyone under one roof, or at least on the same grounds.

Capacity can differ by building or plan, so please check each property’s official website for the latest details.

Tips for choosing
- “How many can stay” and “how many can sleep well” are different things. The larger the capacity, the more comfort depends on the mix of beds and futons. Confirm bedroom counts and bedding on the official site before booking.
- Watch the pricing unit. Per-building and per-person listings are mixed together. This article separates per-night and per-person figures, but with large groups the totals can diverge widely. Run the numbers before comparing.
- Separate buildings, or one house for everyone? Whether you want the whole party in a single building or spread across buildings on the same grounds changes your options.
- Book through the official site. TOMARIBI links to each property’s official website and official booking page.
In closing
A big-group trip is half won once the stay is settled. Large-capacity stays are gathered on the group stays feature page, and advanced search lets you filter by party size and facilities.
