Located in Ichikawamisato, Yamanashi in Japan, which boasts a 1000 year history of paper making, the Japanese paper (washi) maker ONAO and award-winning industrial designer Naoto Fukasawa have teamed up to create the SIWA series.
Fukasawa discerned that the special texture of Naoron, a hard-to-tear paper developed by ONAO, emerged when the paper was crumpled, and suggested design for everyday goods that harnessed this.
The name SIWA is both a reversing of the characters in the word washi (wasi), and a word meaning, "crinkle" in Japanese. As with leather goods, these washi products are lovingly, individually crafted.
Soft Naoron is a paper developed by ONAO from wood pulp and polyolefin utilizing the washi-suki paper manufacturing method. It is soft and flexible, highly water-resistant and does not tear easily. Soft Naoron does not emit noxious fumes when burned.
