暗黙の了解

• 読み: あんもくのりょうかい
• ローマ字: anmoku no ryōkai
• 漢字の分解: 暗黙 (silent/tacit) + の (possessive) + 了解 (understanding/agreement) → silent understanding
• 発音: /aɴ.mo.ku.no.rjoː.ka.i/

意味

An unspoken agreement or tacit understanding — the invisible rules everyone follows without anyone explicitly stating them.

One of the most important concepts for understanding Japanese social dynamics. 暗黙の了解 describes the vast layer of unwritten rules that govern behaviour in Japan: don't leave before your boss, don't eat smelly food on the train, don't directly refuse a request. These rules are never explicitly taught but are expected to be absorbed through social osmosis. Breaking them marks you as 空気が読めない (unable to read the room).

例文

1. 先輩より先に帰らないのは暗黙の了解みたいなもんだよ。
2. 暗黙の了解が多すぎて外国人には分かりにくいと思う。
3. この業界には暗黙の了解がたくさんあるから気をつけて。
