In short: Ki no Tsurayuki was a titan of Japanese literature, serving as a high-ranking court noble and the chief editor of the first imperial waka anthology. Yet, he is equally remembered for a mysterious, anonymously published travelogue written entirely from the perspective of a woman, sparking centuries of scholarly debate.

Born in the late 9th century, Ki no Tsurayuki was a central figure of the Heian period. In 905, Emperor Daigo commissioned him to lead the compilation of the Kokin Wakashū, the inaugural imperially-sponsored anthology of waka poetry. Tsurayuki’s contribution went beyond mere selection; he authored the Japanese preface, a landmark critical essay that categorized waka genres and offered candid, sometimes harsh, critiques of his predecessors, including the renowned Ariwara no Narihira.

Tsurayuki’s literary legacy is inextricably linked to his life as a courtier. He held various provincial governorships, including a term in Tosa Province from 930 to 935. Upon returning to the capital, he wrote the Tosa Nikki, or Tosa Diary. The text is a 55-day account of his journey home, yet it adopts the persona of a woman. This stylistic choice has long fascinated researchers, who analyze the work to understand the complex intersections of gender, social status, and linguistic conventions in Heian society.

The diary is more than a travelogue; it is a deeply personal document that references significant life events, such as the death of his daughter. Tsurayuki’s influence was cemented by his inclusion among the Thirty-six Poetry Immortals, a prestigious group selected by Fujiwara no Kintō. His work continued to resonate long after his death in 945, with his poems appearing in major collections like the Hyakunin Isshu, compiled centuries later by Fujiwara no Teika.

While Tsurayuki’s official career is well-documented in the Sanjurokunin kasenden, his personal life remains obscured by the conventions of his time. The names of his mother and wife were never recorded, a common occurrence in the Heian period. Despite this, his role as a waka master is undisputed; he even appears in the Tale of Genji, illustrating his enduring status as a pillar of Japanese poetic tradition.
