Daiichi Sagami-yu is very proud of its highly carbonated artificial hot spring! In Germany, a place where carbonated water could be naturally found in abundance is called “hot spring of the heart” and has been attracting local people for centuries as it has excellent medicinal effects. Now, you can try a similar kind of hot spring in your neighborhood. Of course, natural black water and regular hot springs are also available. With our motto of “clean and comfortable hotsprings”, we cordially welcome you to our bath house!
