KamenoiHotelKujukuri

A spectacular panoramic hot spring overlooking the horizon of Kujukuri, and a sauna-equipped luxury villa opening in 2025

Chiba Asahi City

"Kamenoi Hotel Kujukuri" is a hot spring hotel in Asahi City, Chiba Prefecture, where you can enjoy ocean views of Kujukuri Beach. From the panoramic large bath on the 10th floor, the Pacific horizon stretches out before you, offering an overwhelming sense of openness through what feels like an infinity hot spring, as if the sea and the bath were connected. The water uses the strong saline natural hot spring Asahi Kujukuri Onsen (chloride spring), which warms the body from the core and helps you stay warm even after leaving the bath. In April 2025, a luxury villa building was also opened, featuring fully equipped private saunas with self-löyly in every room and spacious terraces, allowing you to enjoy an indulgent totonou stay with your beloved dog or family.
