やる気ない

• 読み: やるきない
• ローマ字: yaruki nai
• 漢字の分解: やる気 (motivation/will to do, from やる to do + 気 spirit) + ない (not/none) → no motivation
• 発音: /ja.ɾɯ.ki.na.i/

意味

Unmotivated, zero effort — expressing a complete lack of motivation or willingness to do anything.

A universally relatable expression that captures the feeling of total motivational emptiness. While the individual words are standard Japanese, the phrase as a standalone complaint has become a staple of casual conversation, especially on Monday mornings, during boring meetings, or when facing unwanted tasks. It's often said with a sigh or flat tone, and pairs naturally with wanting to go home (帰りたい). The phrase is so common it's essentially the unofficial motto of the Japanese workforce.

例文

1. 今日まじでやる気ないわ、帰りたい。

3. 月曜の朝からやる気ないの、みんな同じでしょ。
