空気
Kuuki
くうき
Beyond its literal meaning of 'air,' 空気 refers to the unspoken atmosphere, implicit consensus, or shared feeling in a social situation. The phrase '空気を読む' (kuuki wo yomu, 'to read the air') — meaning to pick up on social cues without being told — is a core concept in Japanese communication. Related expressions include '空気が重い' (the mood is heavy/awkward), '空気になる' (to become invisible/fade into the background), and '空気を壊す' (to kill the vibe). Mastering this concept is essential for understanding how Japanese social dynamics work.
