Who compiled the standard Ogura Hyakunin Isshu?

Fujiwara no Teika compiled the standard Ogura Hyakunin Isshu.

Teika was a major late-Heian and early-Kamakura waka poet, critic, calligrapher, and anthologist. According to the account recorded in his diary Meigetsuki, his son Tameie asked him to arrange 100 poems for Tameie’s father-in-law, Utsunomiya Yoritsuna, whose residence near Mount Ogura was being decorated.

Teika selected poems from earlier imperial anthologies and other literary sources, pairing one poem with each of 100 poets. The collection therefore reflects both his personal taste and his judgment about the historical importance of Japanese verse.

The title can cause confusion because “Hyakunin Isshu” describes a format—one poem by each of 100 people—and several later collections used similar titles. The Ogura version, however, is the famous standard one associated with Teika, not with Emperor Daigo, Matsuo Bashō, or Ki no Tsurayuki.
