Precisely braided silk cords, known as kumihimo, are reflected on the mirror-like metal surface. What appears is an infinite microcosm of delicacy, elegance, and stateliness. We call this atmosphere rin in Japanese.
kumihimo, created with expert craftsmanship, incorporates the warmth and richness of silk, beautiful color and pattern, along with flexibility and strength. It creates the final touch of perfection to a kimono when it is fastened together with the obi. These impressive qualities are what attracted designer Kyo Yasuda. In order to extract these alluring elements, he came upon the idea of enveloping a person.
Takashi Fukuda and his son, Ryuta of Ryukobo, a kumihimo studio in Nihonbashi, Tokyo, responded to Yasuda’s passion for choosing mitakegumi. Mitakegumi is a type of kumihimo that creates a noble impression via the use of vibrant colors and the gloss of silk, while still possessing superior elasticity. By weaving air together with the silk cord, the seat of RIN is soft, yet firm, and offers an unexpected level of comfort higher than ever experienced.
The form of stainless steel with a mirror finish on inner surfaces accentuates the beauty of kumihimo. A skilled metal polisher from the Tsubame-Sanjo area in Niigata Prefecture, created this smooth surface that almost glows by hand, polishing it at the microlevel.
The harmony of design and craftsmanship in RIN has created a unique presence beyond comparison.。

An infinite microcosm of delicacy, elegance, and stateliness.
