〜にかかわる: 'To Relate To / Affect' (Meaning + Examples)
Saying something is at stake
〜にかかわる marks that a noun (often something serious — life, honor, future, trust) is directly affected or threatened by the situation being described. It's common in warnings and formal writing.
この薬は使い方を間違えると命にかかわる。
この くすりは つかいかたを まちがえると いのちに かかわる。
If you misuse this medicine, it can be life-threatening.
命にかかわる = a fixed, very common phrase for 'life-threatening.'
やったんは、会社の信用にかかわる問題だと真剣に説明した。
やったんは、かいしゃの しんように かかわる もんだいだと しんけんに せつめいした。
Yattan seriously explained that it was an issue affecting the company's trust.
この決定は今後の進路にかかわるから、慎重に考えたい。
この けっては こんごの しんろに かかわるから、しんちょうに かんがえたい。
This decision affects my future path, so I want to think it over carefully.
Attaching to a noun
〜にかかわる attaches directly after a noun and functions as a verb (かかわる, ru-verb group) or, before another noun, as かかわる + noun.
| Attaches to | Pattern | Example |
|---|---|---|
| Noun (something at stake) | 名詞＋にかかわる | 命にかかわる (life-threatening) |
| Modifying a following noun | 名詞＋にかかわる＋名詞 | 名誉にかかわる問題 (a matter affecting one's honor) |
健康にかかわる情報だから、みんなに伝えたほうがいい。
けんこうに かかわる じょうほうだから、みんなに つたえたほうが いい。
It's information that affects people's health, so it's better to share it with everyone.
Here にかかわる modifies 情報 directly, like an adjective phrase.
Don't confuse with 〜に関して (について)
〜に関して／〜について just means "regarding / about" a topic — neutral, no stakes implied: 天気について話す ("talk about the weather"). 〜にかかわる is stronger: it means the noun is genuinely affected or endangered. You wouldn't say 天気にかかわる話 for small talk about weather — but 台風は交通にかかわる大問題だ ("the typhoon is a serious problem affecting transportation") fits naturally.
The short version
- 〜にかかわる = "relates to / concerns / affects" — implies something important is at stake.
- Attaches to: noun + にかかわる (as a verb) or にかかわる + noun (as a modifier).
- Nuance/register: formal, often serious — life, honor, trust, future.
- Don't confuse with: 〜について／に関して, which is a neutral "regarding," with no implied stakes.
Practice it
