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.

If you’ve ever dreamed of swimming with jellyfish without turning into a human pincushion, your fantasy is not only possible—it’s floating in the heart of Indonesia.
