意味

Death march — an extremely grueling work period with unrealistic deadlines, minimal rest, and intense pressure to deliver.

Originally from software engineering, デスマーチ describes the nightmare scenario of a project with an impossible deadline where team members work around the clock. It became infamous in Japan's IT industry during the 2000s-2010s, where chronic understaffing and poor project management led to routine death marches. The term has expanded beyond IT to describe any period of relentless crunch. It's often discussed alongside karoshi (death from overwork).

例文

1. あのプロジェクト、完全にデスマーチに突入してる。
2. デスマーチで3週間まともに寝てない、限界だ。
3. デスマーチになるのは、だいたい見積もりが甘いからだよ。
