An open-air “sky” bath 35 meters above ground 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 Accommodation with over 90 years of heritage: “Michitekuru Kokoro no Yado Kichimu.” Selected for “100 Best Hotels & Ryokan in Japan Chosen by Professionals,” and also for “100 Best Accommodations to See the Sunset.” The view from the open-air bath 35 meters above ground, overlooking the sea, is truly breathtaking. From the guest rooms, as well as the large public bath and lobby, you can enjoy panoramic views of Uchiura Bay and the beautiful Pacific Ocean beyond—offering an open, soothing stay. For dining, savor exquisite kaiseki cuisine created through the masterful skills of our head chef—recipient of the “2020 Yellow Ribbon Medal”—and carefully selected seasonal seafood and mountain delicacies from Boso. Please indulge to your heart’s content in Kichimu’s distinctive hospitality, named with the wish that every traveler who visits will have good dreams.

  • Thank you very much for taking such great care of us during our stay.As it was just after the reopening, the Facility felt brand new, and we were able to spend our time comfortably in a clean environment.In the large public bath, the scent of wood instantly helped us unwind, and the ocean view through the full-height windows was breathtaking. Even though we were on the east side of the Boso Peninsula, we were surprised to be able to see the sun setting—and it was so beautiful that we couldn’t take our eyes off it. It truly deserves its place among “Japan’s 100 Best Accommodations with Sunset Views.”The rooftop open-air bath we used before bed was softly lit with indirect lighting and had a calm atmosphere. Soaking while listening to the sound of water flowing into the tub made all our everyday fatigue melt away, and we could relax from the bottom of our hearts. It was a wonderfully soothing moment.We enjoyed both dinner and breakfast.The new dining venue had a Japanese-inspired design, creating a lovely atmosphere and a comfortable space.Dinner was served half-buffet style. We were first served sashimi, beautifully presented with an impressively fresh taste.We were also surprised to be served abalone and splendid alfonsino (kinmedai). The abalone remained tender even when grilled, and the kinmedai had an elegant flavor.The buffet also featured an excellent live kitchen: tempura was freshly fried, and there was even Kazusa beef steak. Both were tender, making for a highly satisfying dinner.Breakfast was also buffet-style, and we were amazed by how extensive the selection was. In addition to standard items like salads, there were also sashimi and overnight-dried fish.The turban shell curry (sazae curry) left a lasting impression with its rich flavor, and the nikujaga comforted us with its gentle taste.At the live kitchen they made omelets for us—large portions with great volume—another very satisfying dish.Our Room was spacious and spotless. Above all, through wall-to-wall glass windows stretching across one entire side of the Room, there was nothing but ocean—so much so that we found ourselves sitting in chairs simply gazing outside for quite some time.Fireworks were launched from right in front of us at the fishing port as well—it was incredibly powerful up close. We had never seen fireworks from such close range before, making it an unforgettable experience.And most impressive of all was truly the service provided by your staff.We felt thoughtful attention everywhere throughout our stay; their hospitality was consistently attentive.It made for an extremely comfortable visit—a day we were completely satisfied with.When we visit Kamogawa again, we would love to stay here again.
