Everything you need to know about this live stream
A Legendary Hot Spring Valley
Sainokawara Park sits at the upper end of Kusatsu Onsen, a celebrated spa town in Gunma Prefecture. Hot spring water surfaces across the entire valley floor, gathering into shimmering thermal pools and trickling into the Yukawa River. The site was historically known as the "Demon's Spring" for its sheer volume of water.
Scenery and Surroundings
The webcam overlooks stone-lined bathing channels, rugged rock formations, and a riverside promenade framed by forested slopes. Steam rises continuously where mineral-rich water meets the cool mountain air, a signature sight of this volcanic resort region.
A Stroll Through Kusatsu
Just upstream from the famous Yubatake hot water field, the park caps off a lively street of shops and eateries. Visitors often wander through in yukata robes, making it one of the town's most photographed corners.
