Tucked away in the forested hills of Kumamoto, Japan, there's a waterfall that doesn’t just flow—it invites you in. Nabegataki Waterfall may not be the tallest or the loudest in Japan, but it offers something far rarer: the chance to walk behind the cascading water and stand inside the waterfall itself. And if you come early in the morning, when fog still clings to the trees, the scene takes on an almost mythical quality—as if you’ve stepped through a veil into another world.

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.
