There are places in the world that don’t just show you nature—they tell you stories. And then there’s Lake Mashū, a mystical caldera lake nestled in the mountains of Hokkaido, Japan. Known for its mirror-like waters and often shrouded in fog, Mashū is mysterious on any given day. But once a year, it unveils something truly otherworldly: the Dragon Eye.

Imagine standing by a quiet riverbank in rural Japan, the air heavy with the scent of summer grass. The last traces of daylight have slipped away, and for a moment, darkness surrounds you. Then—like magic—tiny green lights begin to flicker in the air. One, two, dozens... dancing in silence.
