Ono no Komachi

was a Japanese waka poet, one of the "Rokkasen" — the six best waka poets of the early Heian period. She was renowned for her unusual beauty, and "Komachi" is today a synonym for feminine beauty in Japan. She also counts among the Thirty-six Poetry Immortals.
Life.
Almost nothing of Komachi's life is known for certain, save for the names of various men with whom she engaged in romantic affairs and whose poetry exchanges with her are preserved in the "Kokin Wakashū". She was probably born between 820 and 830, and she was most active in composing poetry around the middle of the ninth century.
Extensive study has gone into trying to ascertain her place of birth, her family and so on, but without conclusive results. The Edo-period scholar Arai Hakuseki advanced the theory that there was more than one woman named Komachi and that the legends about her referred to different people. This theory was later expanded to conjecture that there were four "Komachis". It has been conjectured that she was a in the service of Emperor Ninmyō, and when the latter died in 850 she started relationships with other men.
According to one tradition, she was born in what is now Akita Prefecture, daughter of Yoshisada, Lord of Dewa. The Noh play "Sotoba Komachi" by Kan'ami describes her as "the daughter of Ono no Yoshizane, the governor of Dewa". Her social status is also uncertain. She may have been a low-ranking consort or a lady-in-waiting of an emperor.
The headnote to poem #938 in the "Kokinshū" implies she had some sort of connection to Fun'ya no Yasuhide.
Legends.
 had developed as early as the eleventh century. They were later used extensively by the writers of Noh plays.
Stories abound of Komachi in love. One of the legends about her is that she was a lover of Ariwara no Narihira, her contemporary poet and also a member of the Rokkasen. It has been speculated that this legend may derive from the perhaps-accidental placement of one her poems next to one of Narihira's.
Another group of legends concern her cruel treatment of her lovers, notably Fukakusa no Shōshō, a high-ranking courtier. Komachi promised that if he visited her continuously for a hundred nights, then she would become his lover. He visited her every night, regardless of the weather, but died on the ninety-ninth night.
A third type of legend tells of an aged Komachi, forced to wander in ragged clothes, her beauty faded and her appearance so wretched that she is mocked by all around her, as punishment for her earlier mistreatment of her lovers. Yet another group of legends concern her death, her skull lying in a field; when the wind blows through the skull’s eye socket the sound evokes Komachi's anguish.
A different categorization system for Komachi legends was given by Masako Nakano. She gives five groupings:
Poetry.
Almost all of Komachi's extant poems are melancholic. Poet and translator Kenneth Rexroth and Ikuko Atsumi said of her poetry:
Her beauty may be legendary but her rank as one of the greatest erotic poets in any language is not. Her poems begin the extreme verbal complexity which distinguishes the poetry of the "Kokinshū Anthology" from the presentational immediacy of the "Man'yōshū.
Most of her waka are about anxiety, solitude or passionate love. In the "Kokinshū", all but one of her poems—the one that later appeared in the "Hyakunin Isshu", quoted below—were classified as either "love" or "miscellaneous" poems. She is the only female poet referred to in the of the anthology, which describes her style as "containing naivety in old style but also delicacy".
One of her poems was included as #9 in Fujiwara no Teika's "Ogura Hyakunin Isshu":
The poem was originally included in the "Kokinshū" as #133, in the section dedicated to seasonal (spring) poetry. The poem is filled with many layers of significance, with almost every word carrying more than one meaning. It was the subject of a short essay appended to Peter McMillan's translation of the "Ogura Hyakunin Isshu".
In his "Seeds in the Heart", translator, critic and literary historian Donald Keene said that "[t]he intensity of emotion expressed in [her] poetry not only was without precedent but would rarely be encountered in later years. […] Komachi's poetry, however extravagant in expression, always seems sincere." He also praised her poetry along with that of the other poets of the “dark age” of waka in the ninth century in the following terms:
The passionate accents of the waka of Komachi and Narihira would never be surpassed, and the poetry as a whole is of such charm as to make the appearance of the "Kokinshū" seem less a brilliant dawn after a dark night than the culmination of a steady enhancement of the expressive powers of the most typical Japanese poetic art.
Legacy.
The many legends about her have made her the best-known of the Rokkasen in modern times. Until relatively recently, when the title "Miss XYZ" became common in Japan, the woman considered most beautiful in such-and-such town or region would be dubbed "XYZ Komachi". She and her contemporary Ariwara no Narihira are considered archetypes of female and male beauty, respectively, and both feature heavily in later literary works, particularly Noh plays.
Komachi features frequently in later-period literature, including five Noh plays: "Sotoba Komachi", "Sekidera Komachi", "Ōmu Komachi", "Sōshi Arai Komachi" and "Kayoi Komachi". These works tend to focus on her talent for "waka" and her love affairs and the vanity of a life spent indulging in romantic liaisons. Komachi's old age is also frequently portrayed: when she has lost her beauty, has been abandoned by her former lovers, and now regrets her life, wandering around as a lonely beggar woman — albeit still appreciated by young admirers of her poetry. This fictional description is influenced by Buddhist thought and there may be no factual resemblance between it and the historical reality. Komachi is also a frequent subject of Buddhist paintings, which depict her dead body in successive stages of decay to emphasize transience.
Mishima Yukio reworked "Sotoba Komachi" for the modern theater, publishing his version in January 1952. It was first performed the following month. The basic plot (the age-worn former beauty encounters a young poet and relates some of her life's story, which causes him to fall in love with her, with fatal results) is retained, but the action takes place in a public park, with flashbacks to the salons and ballrooms of Meiji-era Japan. An English translation by Donald Keene was published in 1967.
The play "Three Poets" by playwright Romulus Linney includes a one act story about Komachi the poet.
In her honor, the Akita Shinkansen is named "Komachi". A variety of rice, Akita Komachi, also bears her name.
