The surrealistic Blue Pond in Hokkaido, Japan attracts tourists from all over the world. The Blue Pond is located on the banks of the River Bieigawa, southeast of the town of Biei in Hokkaido, as stated by Amusing Planet (amusingplanet.com).
Blue Pond gets its name from the unnaturally bright blue hue of its water. It has an ethereal and enchanting appearance.
The pond wasn’t there from very long. It’s an artificial pond created when a dam was constructed to protect the region from mudflows that might occur from the nearby volcanic Mount Tokachi, after the mountain’s eruption in December 1988. The water blocked by the dam now accumulates in a forest depression creating the Blue Pond.
The blue color of the pond has not been fully explained but is attributed to high amounts of aluminum hydroxide in the water that reflects the shorter wavelength blue light the same way the earth’s atmosphere does.
The color of the pond changes depending on the weather, viewer’s angle, and time of the day.
Though the water appears blue when viewed from the land, the color is not found in the water itself!
