Nichij

Nichij, commonly romanized as nichijō or nichijou, is a Japanese noun meaning "daily life" or "everyday life" (日常). It denotes the ordinary, routine aspects of living and is used across literature, philosophy, and media to refer to the mundane rhythm of day-to-day existence. The word is built from 日 (sun, day) and 常 (usual, constant).

In Japanese usage, nichijō may describe ordinary activities, habits, and social interactions, and it frequently appears in discussions of aesthetics and design that emphasize everyday experience. In popular culture, the term is associated with the "slice of life" genre, which centers on ordinary characters and situations rather than high drama or fantasy.

A notable example is the manga and anime Nichijou (日常), written by Keiichi Arawi, known in English as My Ordinary Life, which uses the concept of everyday life as a source of humor and surreal situations.

Related concepts include 日常系 (nichijō-kei), a genre classification for works focused on daily life, and the broader idea of "everyday life" in sociocultural analysis.
