Meaning

Stress — mental or physical tension from daily life pressures like work, relationships, or environment.

ストレス is one of the most deeply embedded English loanwords in Japanese, used by virtually everyone from children to the elderly. It functions as both a noun and a quasi-adjective (ストレスフル). Japanese society's unique pressures — long work hours, rigid social expectations, packed commuter trains — have made ストレス an essential daily vocabulary word. The concept of ストレス社会 (stress society) is frequently discussed in media as a defining feature of modern Japan.

Examples

1. 仕事のストレスで最近ずっと胃が痛い。 My stomach's been hurting nonstop lately from work stress.
2. ストレスたまりすぎて週末ずっと寝てた。 I was so stressed out that I just slept the entire weekend.
3. 人間関係のストレスが一番きつくない？ Don't you think relationship stress is the worst kind?
