Japanese poet and critic, an innovator of waka (classical court poems) and compiler of the Senzaishū (“Collection of a Thousand Years”), the seventh Imperial anthology of classical Japanese poetry.

As a member of the aristocratic Fujiwara clan, Shunzei followed a career in court from the age of 13. The son and grandson of poets, Shunzei began writing while young; over the decades he employed a variety of styles. Despite his neoclassical orientation, he was more than an imitator of old styles and metres. Chinese descriptive poetry, especially that of the late Tang dynasty (618–907), and Buddhism were important influences on his art. Shunzei is generally considered one of the first major waka poets; his son Fujiwara Sadaie and his granddaughter Fujiwara Toshinari no Musume, whom he helped rear, were also early practitioners of the waka style.

After 1150 Shunzei was noted for his appearances at poetry contests, first as a contestant and then as a judge. He especially emphasized the ideal of yūgen, the subtle communication of romantic beauty with complex overtones of memory and, often, melancholy. He is considered to be the first critic to have recognized the importance of the Tale of Genji. At the age of 63, Shunzei took Buddhist vows, assuming the Buddhist name Shakua. In 1187 he was requested to compile the Senzaishū. Korai fūteishō (1197, revised 1201; “Notes on Poetic Style Through the Ages”) is considered his major critical work.
