Sainokawara Park is a popular spot in Kusatsu along with "Yubatake" and is an 8.5 square kilometer park. Sainokawara Park lies in a valley 450m away from Yobatake and offers a relaxing hike around an area rich with hot spring water. You can hear the sounds of the water trickling around you and even see it collecting in little pools. It's also home to one of Japan's largest outdoor hot springs. After passing Sainokawara Street, which is crowded with tourists and souvenir shops and steamed buns from the Yubatake, lava rolls around and you reach a desolate riverbank where smoke is about to rise. This is Japan's most active hot spring area, with an output of 5,000 liters per minute.15,000 liters of hot springs with a temperature of 50 degrees or higher spring out from everywhere along the Yukawa flowing through the park. Due to the strong acidity (PH1.62) of the hot spring, no vegetation grows on the riverbank. The park is cobbled and has a promenade that makes it easy to walk. Along the way, there is a hot spring pond that gives off a beautiful glow of several emerald greens. Further on the promenade, there is the Sainokawara Open-Air Bath with a total area of 500 square meters. It is a vast open-air bath like a "pond", and if you have time, you should take a bath and it will be a good memory of your trip. Especially at night, it is lit up, and bathing while looking at the starry sky is the best. The natural pools in the park are not for bathing.
The lights are lit up all year round, from sunset to 24:00. If you are staying in Kusatsu, we highly recommend the illumination of Sainokawara Park. Please note that the number of people will be extremely low at night in Sainokawara.
Please bring a towel when you take a footbath or the hot spring in the back.
