A 35-meter-high open-air “sky” bath overlooking Uchiura Bay and ocean-view guest rooms—an experience that delights all five senses with the blessings of the sea and countryside of Minamiboso.

A historic and traditional Onsen Ryokan with over 90 years of history, "Mitchite Kuru Kokoro no Yado Yoshimu." Selected as one of Japan's Top 100 Hotels and Ryokans chosen by professionals, as well as one of the Top 100 Inns with Sunset Views. The open-air bath located 35 meters above ground offers breathtaking panoramic views of the ocean. From the guest rooms, the large communal bath, and the lobby, you can enjoy a sweeping view of Uchiura Bay and the beautiful Pacific Ocean, providing a relaxing and liberating stay. For dining, savor exquisite kaiseki cuisine crafted by our head chef, who was awarded the Medal with Yellow Ribbon in 2020, using carefully selected seasonal seafood and produce from the Boso Peninsula. Experience the heartfelt hospitality unique to "Yoshimu," named with the wish for travelers to have pleasant dreams.

  • This was our second stay in the Scenic Special Room with Jet Bath (Ocean View) (Japanese-Western style).As on our previous visit, both the meals and the hospitality were outstanding. Thank you very much.One suggestion that could make it even better:- In the large public bath, one side has both a sauna and a cold plunge bath, while the other has only a sauna, with no cold plunge bath or relaxation area. For sauna guests, we would appreciate it if both sides could be equipped with a cold plunge bath and chairs for cooling down/relaxing.We will continue to stay here in the future.Thank you again.

  • I booked this place as a year-end treat after working hard all year and wanting to stay somewhere nice.I always choose my trips with food as the top priority, and from the moment I arrived, all the staff were so considerate and welcoming that I immediately felt their warmth. The meals were just as the Reviews said—everything from the appetizers and sashimi to the meat was incredibly delicious. The portions were just right.By chance, we were blessed with pleasantly warm spring weather, and I had a wonderful time strolling along the nearby walking path. It’s also not too far from the station, so if you enjoy walking, I recommend coming on foot.
