Nikki Bungaku

Nikki bungaku (日記文学?) is a genre of Japanese diary literature 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).
