Tips for Choosing

• Narrow down by capacity and bedrooms: The range is wide: kotorine Nasu sleeps 16 and COCO VILLA Nagatoro sleeps 12 for larger parties, while other stays suit groups of 4 to 5. Where bedroom counts are published, they help with planning room assignments for your group.
• How to read the prices: Whole-house rentals are generally priced per building, so the more guests you bring, the lower the cost per person. “From about ¥X” figures are guides as of the time of research and vary by season and day of the week.
• Check the sauna’s “cold plunge”: How you cool down differs by property: the ocean as your plunge pool, barrel saunas, rooftop saunas, and more. You can confirm details in the facility listings on each property page.
• Book on the official website: For availability and the latest prices, each property’s official website is the most reliable source. Please also confirm pet policies and the number of dogs allowed.
