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.
The front desk and staff welcomed us with warm smiles. The building is old, but it was very clean, with no unpleasant odors, so we had a comfortable stay. Best of all, even though it seemed like guests were staying next door, we didn’t hear any noise at all. Both dinner and breakfast were delicious with light seasoning. The all-you-can-drink option was included as well, making it an excellent value. We grilled turban shells and shrimp on the tabletop stove, and in the morning we grilled horse mackerel. We’d definitely like to come again!
Yahoo!トラベルユー... 8/3/2026I made a Reservation for one night and two days (weekday) because I was visiting my parent in the hospital and live far away.Since I wasn’t sure what time I would arrive in the evening, I chose a plan with breakfast only (buffet) and no dinner.The building is a bit old, but it was clean overall, so it didn’t bother me much (though this may vary by person).The Onsen and the ocean-view scenery were great.
