📖 How to use it
Indicates that an action or state extends over an entire period or area.
Attaches to
Attach to a noun expressing a duration or extent: [noun] + にわたって.
This pattern emphasizes that something spans the whole of a specified time or space, often implying a notable length or scale. It is common in news, reports, and formal speech, and is less common in casual conversation. The noun is typically something like 3年間 (three years), 全域 (whole area), or 数回 (several times).

Register
Primarily used in formal writing and speech, such as news, reports, and presentations; in everyday conversation, simpler expressions like ずっと or の間 are more natural.
