The collection of essays "Tsurezuregusa (Essays in Idleness)" written by Yoshida Kenko in 1330-31 is considered as one of the three greatest zuihitsu (collection of writings) in Japan, along with "Makura no Soshi (The Pillow book)" by Sei Shonagon and Kamo no Chomei's "Hojoki (An Account of My Hut)." However, it was not until the Keicho Era (1596-1615) that "Tsurezuregusa" first became critically acclaimed and not until the Edo Period (1603-1867) when it was widely read and studied. During this time it also became the subject of artworks known as tsurezure-e.
