to be related to; to concern with ~
Describes something that is related to or concerns a particular topic, often in an intellectual or cultural context.
This pattern is used to express that something is associated with, related to, or connected to a certain subject. It often appears in formal or written contexts, such as essays, news, or presentations. The noun before it is typically a broad topic like history, culture, or memory. The pattern is not used in casual conversation; in speech, you might hear についての instead, but にまつわる carries a nuance of stories, legends, or things that 'revolve around' the noun. Note that it is a set phrase; you cannot replace に with other particles. The verb まつわる is always in the plain form when used in this pattern, and it does not conjugate for tense in the way you might expect: the whole phrase acts like a modifier before a noun, or it can appear as a predicate with です. For example, この話は、ある事件にまつわるものです means 'this story is related to a certain incident.'
