or is a Japanese literary genre, dating back to Ki no Tsurayuki's Tosa Nikki, compiled in roughly 935. Nikki bungaku is a genre including prominent works such as the Tosa Nikki, Kagerō Nikki, and Murasaki Shikibu Nikki. While diaries began as records imitating daily logs kept by Chinese government officials, private and literary diaries emerged and flourished during the Heian period (794–1192 AD). The English term poetic diary was used by the Princeton University scholar/translator Earl Miner in his book, Japanese Poetic Diaries. Traditionally, composed of a series of poems held together by prose sections, the poetic diary has often taken the form of a pillow book or a travel journal. Since World War II, Beat Generation writers in the United States such as Gary Snyder, Jack Kerouac, Philip Whalen, and Joanne Kyger, as well as post-beat writers such as Andrew Schelling and Michael Rothenberg have studied and written in Western-style poetic diary form. History Although scholars have found diaries dating back to the eighth century, most of those were mere records kept on daily matters of state. At that time, Japan looked to China as a model of culture and civilization and sought to copy Chinese official government diaries. Thus, early Japanese diaries were factual, written in Chinese characters, and influenced by official, male perspectives. Ki no Tsurayuki (c. 872 – 945), a famed poet and author, is credited with writing the first literary diary. His Tosa Nikki, written in 935, records his journey from Tosa in Shikoku to Kyoto through the alleged perspective of a female companion. Departing from the tradition of diaries written in Chinese, Tsurayuki used vernacular Japanese characters, waka poetry, and a female narrator to convey the emotional aspects of the journey. The catalyst of the nikki bungaku tradition, however, is often attributed to Michitsuna's mother and her Kagerō Nikki. In this three part diary, she details the 21-year period between her courtship with Fujiwara no Kaneie and the beginning of her son's courtship. Expressing her personal feelings and exploring her marriage and social situation, Mother of Michitsuna pioneered a new wave of courtier women's kana literature.3 Other exemplars of Heian nikki bungaku include the Izumi Shikibu Nikki attributed to Izumi Shikibu, Murasaki Shikibu’s Murasaki Shikibu Nikki, Sugawara no Takasue no Musume’s Sarashina Nikki, and Fujiwara no Nagako’s Sanuki no Suke no Nikki. Although there remains debate as to whether the nikki bungaku genre, with
