What Is Yojijukugo?

Yojijukugo (四字熟語) literally means "four-character idiom". The term refers to fixed Japanese expressions made of exactly four kanji. Many entries come from classical Chinese literature (漢文), older Japanese sayings, and Buddhist texts.

Unlike ordinary vocabulary, yojijukugo compresses complex ideas, moral values, or situational nuance into four characters. Internal structures vary: some use two pairs (2+2), some use one-plus-three (1+3), and some are four independent kanji working as one expression.

Yojijukugo appears in daily Japanese usage: formal speeches, headlines, lyrics, academic writing, New Year cards, and casual conversation. Mastering yojijukugo signals deeper language command and often matters in Kanken (漢字検定) study.
