空気

• Reading: くうき
• Romaji: kūki
• Kanji breakdown: 空 (empty/sky) + 気 (spirit/energy) → the intangible atmosphere or mood of a situation
• Pronunciation: /kɯː.ki/

Meaning

The atmosphere or unspoken mood of a situation — central to the Japanese concept of 'reading the air.'

While 空気 literally means 'air,' its slang usage refers to the invisible social atmosphere in a room or conversation. The phrase 空気を読む (kūki wo yomu, 'to read the air') describes the prized Japanese social skill of perceiving unspoken feelings and expectations. Failing to do this — being KY (空気読めない) — is a serious social faux pas. This concept is deeply embedded in Japanese communication culture.

Examples

1. あいつ空気読めなくてみんな困ってるんだよ。 That guy can't read the room and it's stressing everyone out.
2. あの発言で一気に空気が変わったよね。 That one comment completely changed the atmosphere, right?
3. 会議の空気がピリピリしてて何も言えなかった。 The tension in the meeting was so thick I couldn't say a word.

Do Say

• 空気読んでよ、今その話する場面じゃないでしょ。 (Read the room — this isn't the time for that topic.)
• あのグループの空気に入っていけない。 (I can't break into that group's dynamic.)

Don't Say

• 初対面の人に「空気読めないですね」は攻撃的すぎる (Telling someone you just met 'you can't read the air' is way too aggressive)

Common Mistakes

• Thinking 空気を読む is about literal air quality — it is entirely about social perception and unspoken cues
• Underestimating how important this concept is in Japanese culture — failing to read 空気 can seriously damage relationships
