In the Kamakura Period a small square cushion called a shitone made of tatami and covered with decorative material was used; and pictures of this can be seen today in the picture cards used in the card game called Hyakunin Isshu.
なお鎌倉時代では茵（しとね）と呼ばれる小さな正方形の薄畳の周辺を飾り布で覆った物（今日でも百人一首の絵札に描かれた図の上でこれを見る事ができる）が用いられていた。
