was a Japanese author, poet and court noble of the Heian period. He is best known as the principal compiler of the Kokin Wakashū, also writing its Japanese Preface, and as a possible author of the Tosa Diary, although this was published anonymously. He is well known for his waka poetry and is counted as one of the Thirty-six Poetry Immortals selected by Fujiwara no Kintō; his poetry was included also in the Hyakunin Isshu. As a courtier, he served as Governor of Tosa (930-935), Vice Governor of Kaga (917-923) and Vice Governor of Mino Province (918-923).

Biography 

Tsurayuki was born in either 866 or 872, the son of Ki no Mochiyuki and a court dancer of the naikyoubou (内教坊), whose name is unknown. He had the childhood name of Akokuso (阿古久曽).

In the 890s he became a poet of waka, short poems composed in Japanese. In 905, under the order of Emperor Daigo, he was one of four poets selected to compile the Kokin Wakashū (Kokinshu), the first imperially-sponsored anthology (chokusen-shū) of waka poetry.

After holding a few offices in Kyoto, he was appointed governor of Tosa Province and stayed there from 930 until 935. Later he was presumably appointed governor of Suō Province, since it was recorded that he held a waka party (Utaai) at his home in Suo.

He was one of the editors of the Kokin Wakashū. Tsurayuki wrote one of two prefaces to Kokin Wakashū; the other is in Chinese. His preface was the first critical essay on waka. He wrote of its history from its mythological origin to his contemporary waka, which he grouped into genres, referred to some major poets and gave a bit of harsh criticism to his predecessors like Ariwara no Narihira.

Tsurayuki composed well over 500 poems throughout his life, including those included in the Kokinshu, imperial collections, and personal collections. One of his waka was included in the Hyakunin Isshu, which was compiled in the 13th century by Fujiwara no Teika.

His death is recorded in the Sanjurokunin kasenden (三十六人歌仙伝) as potentially being May 18, 945, but it is also reported as being on June 30 of the same year.

Works

Kokin Wakashu 
In 905, under the order of Emperor Daigo, Ki no Tsurayuki was one of four poets selected to compile the Kokin Wakashū (Kokinshū), the first imperially-sponsored anthology (chokusenshū) of waka. Tsurayuki was the chief editor of the Kokinshu, and was the author of its Japanese preface (https://en.wikipedia.org/wiki/Kokin_Wakash%C5%AB).

Tosa Nikki 
In addition to the Kokinshu, Tsurayuki's supposed major literary work (though it was published anonymously) was the Tosa Nikki (土佐日記, "Tosa Diary"), which was written using kana. The Tosa Diary is written from the perspective of a woman who embarks on a 55 day trip in 934 to the capital (present day Kyoto), where Tsurayuki had been the provincial governor, from her home in the Tosa Province. The female perspective of the diary, though written by a man (Tsurayuki), has sparked debate among scholars regarding gender and social status within the realm of linguistics of the time period. Ki no Tsurayuki left the Tosa Province at the age of 66 in 934 after completing his term as Provincial Governor and wrote the Tosa Nikki after returning to the capital. There are quite a few references within the diary that allude to events that took place in Ki no Tsurayuki's life, including the death of his daughter. It also includes many poems, presumably written by Tsurayuki.

Tale of Genji
In the Tale of Genji, Tsurayuki is referred to as a waka master, and it is stated that the Emperor Uda ordered him and a number of female poets to write waka on panels as accessories for his palace.

Family 
The names of Ki no Tsurayuki's mother and wife are unknown. He had three children; a son, Ki no Tokibumi; a daughter, Ki no Naishi; and a daughter whose name is unknown.
