Spheres of light float along the tree lined path joining Ueno Park to Kiyomizu-do temple. They move on their own, shining brightly, then disappearing—as if they are softly breathing.

When the spheres of light are touched by a person or receive an impact, the color of their light changes, and they emit a musical tone unique to their new color. The color and tone then resonates out to the spheres around them, and the lights of Shinobazu Benten-do temple  change in concert to emit the same color and tone.
