Piercing Blue

"The Blue Pond is located in the left bank of the River Bieigawa, southeast of the town of Biei in Hokkaido, Japan, about 2.5 km northwest from the Platinum hot springs at the foot of Mt. Tokachi. The pond gets its name from the unnaturally bright blue hue of its water. With tree stumps protruding from the surface of the water, not unlike Lake Kaindy, the Blue Pond has an ethereal and enchanting appearance."
