Ryuo Radon Onsen 
Ryuo Radon Onsen Hotel U-TOPIA
About 2 hours from Tokyo. The hotel is located in Yamanashi Prefecture where there are abundant nature and Mt. Fuji.
The inside of the hotel has a nostalgic Showa retro atmosphere, but it also has hot springs with one of the best therapeutic effect in Japan.
Please experience our hot springs that relive your fatigue and restore your physical and mental health.
Yamanashi has magnificent nature and historical highlights, such as Mt.Fuji, the symbol of Japan, Arakura Fuji Sengen Shrine, where you can see Mt. Fuji, cherry blossoms, and autumn leaves all together, and Shosenkyo, which is said to be the most beautiful valley in Japan, where you can enjoy the scenery of the four seasons up close.
Our hot springs have been selected as one of the 100 best hot springs in Yamanashi, and are the ultimate hot springs for health. You can enjoy the natural hot springs that have been carefully protected since its opening in 1980, and the fresh radon hot springs born from a radon generator.
Our hot spring water has been constantly coming out as it has for the past 50 years, and flowing directly from the source. It is said that only 2% of the hot springs in Japan are 100% natural hot springs. Please feel the difference from circulating hot springs.
Radon Onsen is called inhaling hot spring, and it has a sweating effect more than a sauna, allowing you to experience radon therapy.
Relieve your day-to-day fatigue at our ultimate hot springs.
