N1 has three patterns for expressing "have no choice / be forced to." They all translate similarly but differ greatly in tone and context.
ざるを得ない: Have No Choice But To… (Rational Acceptance)
「ざるを得ない」expresses rationally concluding there's no other option:
| Example | Meaning |
|---|---|
| 証拠がある以上、認めざるを得ない。 | Given the evidence, I have no choice but to admit it. |
| 天候不良のため、出発を延期せざるを得ない。 | Due to bad weather, we have no choice but to postpone departure. |
| この状況では、計画を変更せざるを得ない。 | In this situation, we have no choice but to change the plan. |
Connection: Verb ない-stem + ざるを得ない (する → せざるを得ない) From classical Japanese ざる (= ない) + を得ない (= cannot obtain/do).
Key Points
- Rational judgment: Not emotional — "I've thought about it, there's simply no alternative"
- Primarily written/formal
- Stronger than しかたがない in emphasizing being cornered
余儀なくされる: Be Forced To… (External Pressure)
「余儀なくされる」expresses being compelled by external, uncontrollable forces:
| Example | Meaning |
|---|---|
| 災害が拡大し、二ヶ月間学級閉鎖を余儀なくされた。 | As the disaster spread, they were forced to close schools for two months. |
| 資金不足で、事業の縮小を余儀なくされた。 | Due to insufficient funds, they were forced to downsize. |
Connection: Noun + を余儀なくされる 余儀ない = no other choice available.
Key Points
- Passive form: Emphasizes external force, not personal choice
- Used in news, reports, and formal writing
- Subject is typically the victim/affected party
ハメになる: End Up In a Mess (Unfortunate Result)
「ハメになる」expresses falling into an undesirable situation — casual, with a "my luck…" tone:
| Example | Meaning |
|---|---|
| 友達と買い物に行ったが、結局夜遅くまで付き合わされるハメになった。 | I went shopping with a friend, but ended up being dragged along until late at night. |
| 嘘がバレて、全部やり直すハメになった。 | The lie was found out, and I ended up having to redo everything. |
Connection: Verb dictionary form + ハメになる ハメ = predicament / fix.
Key Points
- Casual/colloquial, with self-deprecating or complaining tone
- The result is always something unwanted
- Much more informal and emotional than ざるを得ない
Bonus: ないではすまない = Can't Get Away Without Doing
「ないではすまない」means social norms demand it — "you can't not do it":
| Example | Meaning |
|---|---|
| 壊したのだから、弁償しないではすまない。 | Since you broke it, you can't get away without compensating. |
Connection: Verb ない form + ではすまない
Comparison
| Pattern | Tone | Formality | Nature |
|---|---|---|---|
| ざるを得ない | Rational resignation | ★★★ | Circumstances force it |
| 余儀なくされる | Forced by pressure | ★★★★ | External force |
| ハメになる | Bad luck / self-pity | ★ | Ended up in trouble |
| ないではすまない | Social obligation | ★★ | Common sense demands it |
Summary
- 「ざるを得ない」= Rational "no choice" (formal/written)
- 「余儀なくされる」= Forced by external circumstances (news/reports)
- 「ハメになる」= Ended up in an unfortunate situation (casual)
- 「ないではすまない」= Can't get away without doing it (social norm)
Self-Check

Show Answer
延期せざるを得ない or 延期を余儀なくされた。 Both work; ざるを得ない emphasizes rational judgment, 余儀なくされる emphasizes being forced.
2. What's the difference between ハメになる and ざるを得ない?
Show Answer
- ハメになる: Casual, self-deprecating (ended up in this mess)
- ざるを得ない: Formal, rational (no other choice) ハメになる is more emotional and colloquial; ざるを得ない is more composed and formal.
