Created in 1988, this man-made Blue Pond was dug to protect the residents from lava flows from nearby Mount Tokachi.

 

A colour produced by the volcano

This simple pond soon became a tourist attraction thanks to the highly saturated blue colour of its water, which seems almost unreal. These unusual colours are not exclusively due to the reflections of the sky on the surface of the water, but also to the aluminium and sulphur hydroxides which whiten the stones in the pond. The trees growing in the middle of the water accentuate the mystical character of the place.

This artificial wonder in Hokkaido was popularised thanks to Apple, who used a photo of the Blue Pond as one of the wallpapers for its computers.
