Enjoy ocean views from every room and indulge in generous seafood cuisine.
Located at the southernmost tip of the Boso Peninsula, this Hotel offers a close view of the Nojimazaki Lighthouse. All rooms feature an ocean view with the Pacific Ocean spreading out right in front of you, and the Property takes pride in its fresh and hearty seafood cuisine unique to Minami-Boso. Dinner is a highly popular buffet where you can enjoy a variety of flavors! Indulge in "seafood grilled on a net" with turban shells and scallops, or create your own "original seafood bowl" by topping sushi rice with your favorite ingredients. You can also enjoy unlimited servings of Boso's specialty namero, freshly fried tempura, and desserts. Additionally, soft drinks are available with unlimited refills. For breakfast, fresh "morning-harvested vegetables" from our own farm and partner farms, "freshly baked croissants," and our homemade "thick omelets" are highly praised.
Many of the staff were older, but they were very friendly and made me happy by chatting with me casually.The tempura chef is 72 years old!!You’d never guess it from how skillful and efficient he is. I was really impressed. I’d love to visit again.
Yahoo!トラベルユー... 9/29/2026We stayed as a family of four. As we were traveling with my elderly mother who has difficulty walking, the hotel kindly lent us a wheelchair. Everyone was very considerate and helpful.We wanted beds rather than futons, but many hotels only offer up to three beds per room, so we were debating booking two rooms or choosing a Japanese-Western style room where someone would sleep on a futon. This hotel had a four-bed room, which was a key reason we chose it.Before entering the room, I worried it might be cramped with the beds pushed together, but it was actually very spacious and impressively clean. The view from the room was also wonderful, and we were able to relax and enjoy our stay.The building does feel a bit old, but considering the reasonable price, we felt it offered excellent value for money.The buffet meals were delicious with plenty of variety—especially the grilled seafood (hamayaki) and the DIY seafood rice bowl (kaisendon), which were outstanding.I would like to give full marks overall; however, there were some steps in certain areas that made it not fully barrier-free. The bathroom floor was slippery in places, there was only one handrail in the bath area, and when the men’s and women’s baths switched between night and morning, there were differences in amenities—having the same amenities available in both would have been better. For these reasons, I deducted some points.Overall, we were satisfied and would recommend this hotel to others.
