Media Art Festival 2018  TX Tsukuba Station passage

Multiple light beams are cast on the wall by changing the angle of the two dichroic mirrors. The angle of those mirror changes by sensing the movement of a person.



Yahata Kitakyusyu City

In the daytime, the transmitted light and the reflected light of dichroic mirror change depending on the position of the sun.

Various light rays are projected on the wall depending on the angle of the mirror at night. Seasonal light programs are available for each season.

Sola & Mizu – Sky & Water


COSMOS is a work of art that casts light onto the escalator hall of New Tokyo International Airport. During the day, the space is filled with colorful beams, as the sunbeam and lights from dicromirror mix with one another.

Every half hour, the shade on windows falls, to prompt a spectacle of light and sound.

Four different spectacles are presented each day: for morning, for afternoon, for evening and for night.

The common theme is the magnificent universe that sprawls from the earth to the cosmos.

Human Genome

When remains of a human body are cremated, the Human Genom-chromosome that contains information unique to the particular human being-is discharged and travels into the air. 

Through the window-long and narrow (20 cm X 4m) with the stripe-pattern 
comprising from prism and polarizing glass, symbolizing disposition of genes-rainbow-colored beams penetrate and project themselves onto the walls of escalator halls.

The beams shift, constantly throughout the year, according to the change in position between the earth and the sun.

Pedestrians experience flicker and change of daylight.
