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.

  • Thank you as always. I don’t think there are many Ryokan where you can enjoy fresh seafood for under 20,000 yen and also use a private open-air bath. The Accommodation staff are incredibly kind, and it’s my hidden getaway—more relaxing than being at my parents’ home. Last time I brought my parents and they were absolutely delighted, so my rating hasn’t changed at all. Of course, at this price there are a few Facility points you may need to overlook, but if that bothers you, you can always pay several times more and stay at a luxury Ryokan. For ordinary people looking for an occasional treat, this is a comfortable Accommodation that’s just right.
