Meaning

Over capacity — a state of being overwhelmed and unable to handle any more tasks, information, or stress.

A Japanese-English compound from 'capacity' (キャパシティ, shortened to キャパ) and 'over' (オーバー), キャパオーバー describes the moment when you have exceeded your mental, physical, or emotional limits. Used for work overload, social burnout, information overload, and emotional exhaustion. Often used self-descriptively to explain why you cannot take on anything more.

Examples

1. 今週キャパオーバーだから新しい仕事は無理。 I'm over capacity this week, so there's no way I can take on new work.
2. やること多すぎてキャパオーバーになってる。 I have too much going on and I've totally hit my limit.
3. 情報量キャパオーバーで頭がパンクしそう。 There's so much information that my brain is about to explode from overload.
