The first form of Fusuma Shoji can be thought as a wooden panel pasted silk cloth with and drawn Chinese paintings or Yamato-e, and later because of pursuing lightweight doors it was changed to the new form with setting kumiko (strips of the wooden lattice positioned vertically and horizontally to make latticework used in gable pediments or sliding screens) on Kamachi and pasting figured silk on both sides for lightweight and decoration of Shitsurai.
ふすま障子の当初の形態は、板戸に絹布を張り唐絵や大和絵を描いたものであったと考えられるが、建具の軽量化という技術課題のなかで、框に組子を設け両面に綾絹を張り、軽量化と室礼としての装飾の目的を達する襖建具が誕生したと考えられる。
