Kami no ko ike
landmark
神の子池
Luminously blue transparent pond deep in forest near Lake Mashu, eastern Hokkaido rare phenomenon.
A tiny, supernaturally clear blue pond fed by underground springs from Lake Mashu. The water stays at a constant 8 degrees Celsius year-round, meaning submerged fallen trees never decompose. The pond's color shifts from cobalt blue in summer to deep indigo in winter.
