What is light?
Humans have pursued this question throughout the development of civilization.
In ancient Greece, medieval Arabia and Europe, philosophers unraveled the theory of light,
inspiring research that continues to this day.
Today, yesterday and tomorrow.
Light will always be essential to our lives.
Now, Nitto is exploring a new form of light.
RAYCREA - The technology enabling new forms of light expression.
As light emerges from RAYCREA, we discover its new possibilities.

Milan Design Week5–10 September 2021

RAYCREA is a technology producing new forms of light expression. Capturing light and color on its surface, RAYCREA opens up new possibilities for surface lighting. To explore these expressions and possibilities, Nitto partnered with architectural lighting designer Kaoru Mende. For the main installation, Mende selected the theme of labyrinth and focused on the magical expressions of RAYCREA. When light hits glass or acrylic covered with RAYCREA film, the transparent panels take on light and color. The expressions created by Mende, who has brought light to various architecture and urban projects, provided a glimpse into the future.
