Shoji paper

Japanese: 障子紙 - しょうじがみ

The base paper for shoji screens. It must be strong, transmit light well, be porous, allow good air circulation, and be resistant to discoloration. It is made from paper mulberry and chemical pulp, but in recent years, it has been produced in large quantities using chemical fibers as the main raw material. It is also produced in a single piece without any seams, but the width and length vary depending on the customs of each region, so in addition to the Hanshi size, there are many other sizes, such as Mino size, Shaku size, Izumo size, and Kagoshima size, as well as different lengths such as Honma size and Hazama size.

Japanese:

障子の地紙。強靭で光線の透過がよく，多孔質で空気の流通が良好なうえに変色しにくいことが必要である。原料はコウゾ，化学パルプなどであるが，最近は化学繊維を主原料としたものが多量に生産されている。継ぎ目なしの一枚張りの生産もみられるが，幅，長さは各地の慣習上，障子の形が異なるので，半紙判のほかに美濃判，尺判，出雲判，鹿児島判などの幅寸法の異なるもの，および本間判，狭間判など長さの異なるものなど多種多様である。
