We stayed at Soboro in Kamogawa, Chiba Prefecture!There were 10 of us, and we enjoyed the pool, sauna, karaoke, BBQ terrace, and even Netflix—everyone had a great time at our own pace!!It was such an amazing Accommodation that we’d love to stay again.Highly recommended for both large and small groups!
んーあいおさん 5/18/2026Spacious and open, we stayed with a small group this time, but I think it would be just as satisfying for a larger group.With well-equipped Facilities such as a sauna, natural Onsen, and a pool, it was the perfect place to relax right in front of the ocean.
