"Encapsulating Life with the Colors of Life”
Bringing the colors of life into everyday life.
I want to bring the colors of nature into your daily life.

I believe in the essence of color using plants, and I make it my business to
help you bring life-giving colors into your daily life!


Riku Matsuzaki


Riku Matsuzaki's Philosophy:

"Nature's colors support people." Before medicine was invented, people used clothes dyed with "natural colors" which is the origin of the word “medication."

The roots of "Japanese Indigo" are in Kyoto, where we return to the basics of fermentation with water, wood ash, and homegrown indigo to create genuine, non-bleeding indigo dye.

Our studio, revives the lost "Kyoto Indigo" from the Taisho era and incorporates the colors of natural plants that have supported humanity, both in art and daily use.

-Encapsulating life with the colors of life-
Riku Matsuzaki, “Kyoto Indigo (Kyoai)” Dyer



In 1990
Riku Matsuzaki was born in Kyoto, Japan.

In 2018
Matsuzaki participated in the restoration of a Tang Dynasty garment held in the Shosoin Repository, Nara, Japan.

Matsuzaki built a “Kyoto indigo dyeing (Kyoai)” factory.
