Ryokan & Glamping Resort: The Inn Where the Sound of Deer Echoes - Hanazansui
Chiba Prefecture/IsumiEscape into nature in just 90 minutes, with an in-room open-air bath and glamping for an extraordinary getaway.
Just a 90-minute drive from the city center, immerse yourself in the pristine nature surrounded by the national forest and streams of Oku-Boso. Enjoy luxurious moments in detached accommodations with private open-air baths or extraordinary glamping experiences. We offer both simple bell tents and premium tents equipped with showers and toilets, ensuring a comfortable stay without the need to bring anything. BBQ amidst nature is exceptional! Relive the excitement of childhood with a thrilling stay.
We visited last year and had an amazing, great-value summer with river play, BBQ, fireworks, and more—perfect for our family with young children—so we came back again this year. We made a mistake during the Reservation process, but the staff kindly helped us, and we were able to make more wonderful summer memories. With easy access from central Tokyo, it’s perfect for anyone who wants to enjoy glamping casually.
Yahoo!トラベルユー... 7/27/2026I stayed in a dome tent. It was equipped with amenities like air conditioning and a refrigerator, similar to a typical hotel, and had a very casual interior design. The meals included a variety of options such as meat and fish, which were highly satisfying. Although there was an issue with the BBQ grill not functioning properly, the staff responded promptly and courteously. I had a very fulfilling glamping experience.
