黙認（もくにん、mokunin）
- tacit consent

The Japanese word 黙認 （もくにん） means to tacitly approve, to condone, or to acknowledge something without formal objection or disapproval. It implies a passive acceptance or tolerance of a situation, action, or behavior, even if it is not explicitly authorized or supported. It’s a subtle form of agreement, where silence or inaction implies consent. It suggests that the speaker or entity is aware of something and chooses not to officially challenge or prevent it. The focus is on the lack of explicit opposition rather than active endorsement.
