Enjoy a relaxing moment while listening to the sound of waves, gazing at the starry sky, and immersing yourself in nature!

Just 90 minutes from Tokyo, after arriving at the Property, you can walk through the pine forest to reach the beautiful Iwai Beach. The sunset is stunning, and if you're lucky, you might even catch a glimpse of Mount Fuji from Iwai Beach. Enjoy a relaxing stroll along the beach in the evening or morning to fully embrace nature. How about trying the local seaside inn cuisine occasionally? Savor the fresh seafood of Minamiboso. A private bath with views of the starry sky or passing airplanes makes for a delightful bath time. We offer a variety of accommodation Plans. We look forward to welcoming you.

  • This was our first stay as a couple with one Chihuahua.We stayed in the villa building, and it felt so comfortable—just like being at home. We also asked to have our meals served in the Room. The breakfast and dinner were both delicious, and we were amazed by the generous portions of sashimi and splendid alfonsino.All of the staff were cheerful and pleasant, and we were completely satisfied with everything!It was an Accommodation that made us want to come back again.We’d also like to visit the coffee shop next time.

  • I usually stay here on solo trips, but this time I stayed in the pet-friendly building with my parents. They were happy that they didn’t have to climb steep stairs, and that meals could be served in the Room, so they didn’t have to worry about being considerate of others. As always, we were very satisfied with the dishes featuring fresh seafood. Having a shower booth is another advantage of the pet-friendly building—you can even wash your hair in the morning. I will definitely visit again, and I’d like to bring my parents back while they’re still healthy.
