意味

One's mental state or emotional condition — used casually to talk about psychological wellbeing.

メンタル has become one of the most commonly used loanwords in casual Japanese, functioning as a noun meaning 'mental state' or 'psychological resilience.' Unlike the English adjective 'mental,' Japanese メンタル is primarily a noun: メンタルが強い (mentally strong), メンタルがやられる (my mental state is wrecked). It normalizes talking about emotional struggles in everyday conversation without the clinical weight of formal psychological terms.

例文

1. 最近メンタルやられてて、何もやる気が出ない。
2. メンタルにくる仕事ばっかで本当にしんどい。
3. 推しの引退でメンタルがボロボロなんだけど。
