KURBIO is a name derived from the combination of the German word "KUR," meaning "healing, recovery, treatment," and the Greek word "BIOS," meaning "life." KUR is often associated with Kurhaus (a Facility for therapeutic and recuperative purposes, often featuring an Onsen), and BIO is commonly heard in recent years in the context of macrobiotics (a dietary approach translated as "the art of longevity"). Kusatsu Onsen Hotel KURBIO is designed with the desire to help guests restore their physical and mental health through both aspects. It offers a serene environment, the renowned hot springs of Kusatsu, and daily meal menus based on macrobiotics. This is a new style of healthy resort that has not existed in Japan before.

Mount Akagi, one of Japan's 100 Famous Mountains, is located about two hours from the city center. From the windows of Aoki Ryokan, which has been in operation on Mount Akagi since 1875, you can enjoy a panoramic view of Lake Onuma and the highest peak, Mount Kurohime. Witness the mountains reflected upside down on the mirror-like calm surface of Lake Onuma after the morning mist clears, the stunning sight of Mount Kurohime bathed in the red hues of sunset, and the star-filled night sky against the pitch-black backdrop.The retro-style interior of the Ryokan, built with natural wood from Mount Akagi, exudes warmth and offers a tranquil atmosphere. Meals prepared with locally sourced ingredients are crafted by a seasoned chef, featuring specialties such as smelt, Joshu pork, sashimi konjac, mountain vegetables in spring, mushrooms in autumn, hearty winter hot pots, and salt-grilled sweetfish and trout, all of which are popular choices.The main building offers a variety of Japanese-style Rooms, a 70-tatami mat banquet hall, a panoramic bath overlooking Lake Onuma, and a "dining area" with sunken kotatsu-style seating for dinner. Breakfast is served at "Restaurant Numajiri," where you can enjoy the view of Lake Onuma. Next to the restaurant, there is a shop selling souvenirs and beverages. Across the parking lot, on the lakeshore, is a private cottage-style annex called "Jurin," where you can relax and sleep comfortably in a bed. The water flowing through the Ryokan's taps is all natural spring water drawn from the mountains. The baths heated with this spring water are known for their smooth texture and warming effect. Additionally, rice cooked with this soft, cold water and drip coffee made with it are highly praised for their unique taste.Located at an altitude of 1,350 meters, the shores of Lake Onuma are about 10°C cooler than the city center, making it an ideal summer retreat, often referred to as "the entire mountain is air-conditioned." In winter, the area experiences cold temperatures comparable to Hokkaido, and Lake Onuma becomes a rare spot in the Kanto region for ice fishing for smelt. From September to November, boat fishing is also available. Fishing equipment, boats, and tents can be rented from Aoki Ryokan's "Fishing Support Boat Service."Mount Akagi features two caldera lakes, Lake Onuma and Lake Konuma, as well as the high-altitude marshland of Kakumanbuchi. Peaks such as Mount Kurohime, Mount Jizo, Mount Suzuga, and Mount Arayama offer breathtaking views. Birds flit among the trees, including birch, Erman's birch, and Mizunara oak, filling the air with their songs. Well-maintained hiking and walking trails allow visitors to enjoy the natural beauty of the area throughout the seasons. Snow-covered Mount Akagi is also ideal for beginners in winter mountain climbing. Whether it's the silver-white winter, the lush green summer, the red azaleas of spring, or the vibrant autumn foliage, Mount Akagi offers a unique charm in every season.There is nothing but abundant nature here. It is our joy to provide a place where you can relax and enjoy the beauty of Mount Akagi. We warmly invite you to visit Aoki Ryokan, a lakeside Property on Mount Akagi.
