Hand-made Decorative Washi Paper
Kowith Flame-Resistant FinishingShu

KoShu is a decorative board made from washi paper. Washi paper is traditional
Japanese paper, which has over 1,500 years of history in Japan. Washi paper ishandmade from tree fibers by washi masters who dedicate their lives to studying thecraft. Cold water prevents the decomposition of the fibers, so the intricate process ofwashi paper-making was traditionally only carried out during the coldest months of theyear. The washi paper used for KoShu is created in the Echizen region, whose harshand snowy winters lent itself well to masterful washi creation.
The name KoShu comes from combining the Japanese characters for "Echizen(越)","tree(木)", and "winter(冬)".

Echizen Washi : 1,500 years of tradition

Easy Installation - Anywhere

This hand-made washi paper perfectly displays the tradtional beauty ofJapan. Echizen-washi paper has the oldest history of any washi-maker inJapan. Each piece is delicately hand-crafted one at a time bywashi-craft-masters who have spent years dedicated to perfecting this ancientartform. KoShu isn't just your typical design piece: it is also a method of
keeping this traditional craft alive and sharing it with the world from Japan.

KoShu can be installed easily anywhere. Traditionally, washi-paper art could only
be installed by washi-professionals, as the delicate paper required special
handling techniques. However, KoShu's special coating and creation process
makes it more durable and able to be handled by any installers. A combination of
double sided tape and adhesive bonding also allows the board to be attachedeasily and securely to any wall. The size of the panels can be changed easily prior
to installation: simply cut them with a carbide saw, and finish it with a special
framing piece which keeps the edges straight and neat.

Fukuvi's Original Flame-Resistant Coating Design
Until now it was impossible to coat washi paper without ruining the integrity ofthe paper. However, Fukuvi was able to develop a method of coating washi
paper to give it flame-resistant capabilities without losing the original texture
or charm of this traditonal cultural craft.
