Yoshida Kenkō (born c. 1283, Kyōto?—died c. 1350/52, near Kyōto?) was a Japanese poet and essayist, the outstanding literary figure of his time. His collection of essays, Tsurezuregusa (c. 1330; Essays in Idleness, 1967), became, especially after the 17th century, a basic part of Japanese education, and his views have had a prominent place in subsequent Japanese life.
He early served at court and took Buddhist orders after the death of the emperor Go-Uda in 1324; but becoming a priest did not cause him to withdraw from society. On the contrary, he continued to take active interest in all forms of worldly activities, as his essays indicate. His poetry is conventional, but the essays of Tsurezuregusa display a perceptiveness and wit that have delighted readers since the 14th century. Lamentations over the passing of old customs express his conviction that life had sadly deteriorated from its former glory.
Tsurezuregusa has also been acclaimed for its sections treating aesthetic matters. Beauty for Yoshida implied impermanence; the shorter-lived a moment or object of beauty, the more precious he considered it.
