The concept is "ESSENCE OF LIGHT", and the basin and natural stones are arranged so that you can feel the quiet appearance, sunlight, and gentle breeze by the sequence of light. The art and materials placed in various places are also created with the image of the concept.
In the main hall with a high sky, a symbolic form was created by the design of the crossed wooden lattice with the motif of a Japanese umbrella on the ceiling. The sunlight leaking from that form creates various fleeting forms, and you can feel the beautiful light that matches the movement of your line of sight.
