You can feel the passage of time through the natural beauty visible from the Hotel. A stunning property, HOTEL OOSADO. In the spring of 2024, we will further renovate, offering a luxurious lounge and high-grade guest rooms, providing truly blissful moments. Enjoy a soothing stay that refreshes your soul.

  • I have stayed at many Accommodations across the whole country, and this was by far the best in terms of service.Not only are the Facilities excellent—such as complimentary drinks and a footbath—but above all, I was truly moved by the warm hospitality of the staff. In particular, I will never forget the sincere and attentive service provided by a tall male staff member.Normally, my wife’s stomach gets tired during a Multiple Night Stay, so we chose to stay just one night this time. However, we were told that meal arrangements could be adjusted if we informed them in advance. I regretted not staying longer.Next time, I would love to visit again for about three nights and relax.

  • This was our first trip to Sado Island as a couple. Unfortunately, it rained, and we thought we might not be able to see the Hotel’s famous sunset, but the rain stopped just in time and we were able to enjoy a truly wonderful view. The meals were delicious, and the large public bath was great as well. But what impressed us most was the outstanding hospitality of the staff. They kindly provided Shuttle Service for us as we were traveling by bus, and we also saw them offering thoughtful assistance to other guests in many situations. We had a hard time choosing a Hotel on Sado Island, but we are truly glad we chose this one. Thanks to everyone on the staff, our trip to Sado Island became something really special. Thank you for such a wonderful time!
