In "The Pillow Book," she wrote about everything of interest to her during her life in the Imperial Court of the Heian period, and it includes 'Monowazukushi' (listing items like Utamakura (a place famed in poetry)), excellent poems, observations on daily life, comments on people, and reminiscences, so it also seems to be a record, etc.
『枕草子』には、「ものはづくし」（歌枕などの類聚）、詩歌秀句、日常の観察、個人のことや人々の噂、記録の性質を持つ回想など、彼女が平安の宮廷ですごした間に興味を持ったものすべてがまとめられている。
