Yunishigawa Onsen Kokoro River Light Festival

湯西川温泉心川あかり

Colorful “Yamahotaru” lights in seven hues are gently released into the Yunishigawa River.
As they shimmer and drift along the water’s surface, they create a truly magical and dreamlike scene.
This enchanting event transforms the cool mountain stream of Yunishigawa into a flowing river of seven-colored jewels.
