to relate to; to have to do with
States that something relates to or has to do with a certain matter, often with a sense of being directly involved or affecting it.
This pattern is used to express a relationship between a subject and a noun, indicating that the subject is connected to, involved with, or has an impact on that noun. It is often used in formal or serious contexts, such as discussions about society, work, or personal matters. Unlike について, which simply means 'about', に関わる implies a stronger, more direct involvement or consequence. For example, saying 命に関わる means something is life-threatening, not just about life. The pattern is common in written Japanese and formal speech, so you will encounter it in news, essays, and business settings.
