This survey was conducted over a year, covering the entire Kanto region.
📖 Explanation & Nuance
'〜にわたって' indicates that something extends over a whole range of space, time, or scope. '〜に至るまで' emphasizes the endpoint of a range, often something extreme or surprising, and is typically used in the pattern 'AからBに至るまで' (from A to B). Here, the sentence describes the survey covering the entire geographical area ('関東地方全域'), so 'にわたって' is the correct choice to express this scope.
「〜にわたって」は、時間や場所、範囲の全体に及んでいることを示します。「〜に至るまで」は、「AからBに至るまで」の形で使われ、範囲の終点Bを強調し、それが意外なものであることを示すニュアンスがあります。この文では、「関東地方全域」という地理的な範囲全体に調査が及んだことを示しているため、範囲全体を表す「にわたって」が適切です。
