About the Piece

 This piece expresses the passage of time from the quiet beginning of night to its gentle end—through light.

Using a built-in GPS module, it automatically turns on at sunset wherever you are in the world.
As the night deepens, the light gradually turns off from one side, eventually shutting off completely with the sunrise.

In Japan’s Edo period, a timekeeping system called futeiji-hō was used, which was based on sunrise and sunset.
People adjusted their working and sleeping hours according to the seasons.

This piece quietly reconnects us to the rhythms of nature—something that has become harder to sense in modern life—through flickering, gentle light.
