辛い vs 苦しい — both describe suffering or hardship, but they capture different kinds of pain. Knowing the difference helps you express yourself more precisely in Japanese!


These two words are both important for talking about difficult emotions and situations. Let's explore the nuance so you can use each one naturally.
At a Glance
| Word | Reading | Meaning | Nuance |
|---|---|---|---|
| 辛い | つらい | Hard, painful, tough (emotionally) | Emotional or situational difficulty — something weighs on you |
| 苦しい | くるしい | Suffering, agonizing, anguished | Deeper physical or psychological anguish — intense suffering |
辛い (つらい) — Hard / Tough / Emotionally Painful
辛い describes something that is hard to bear, difficult, or emotionally painful. It's the word for tough situations, painful relationships, or emotionally draining circumstances. It doesn't have to be extreme — it just means things are hard.
- 辛い経験 — a painful/hard experience
- 辛い仕事 — a tough job
- 別れが辛い — the separation is painful
- 辛い思いをする — to go through a painful/hard experience


一人暮らしは自由だけど、時々辛くなる。
Living alone is free, but sometimes it gets tough/lonely.
| Japanese | English |

| 仕事が辛くて泣いた。 | Work was so tough I cried. |
苦しい (くるしい) — Anguish / Intense Suffering
苦しい describes a deeper, more intense suffering — physical or psychological anguish, agony, or distress. It often implies struggling to breathe, severe pain, or being overwhelmed by hardship.
- 胸が苦しい — my chest is tight / aching
- 生活が苦しい — life is a financial struggle
- 息が苦しい — I can't breathe well / it's hard to breathe
- 苦しい立場に立たされる — to be put in an agonizing position


苦しい has a stronger physical or economic weight than 辛い. 生活が苦しい (life is a financial struggle) is a very common phrase in Japanese — it means money is very tight. 辛い would express the emotional pain of that, while 苦しい emphasizes the struggle itself.
| Japanese | English |
|---|---|
| 登山で息が苦しくなった。 | I got short of breath while mountain climbing. |
| 生活が苦しくて貯金ができない。 | Life is a financial struggle and I can't save money. |
| 彼の言葉が胸に刺さって苦しかった。 | His words pierced my heart and caused me anguish. |
