How to say "coverage" in Japanese
Choosing the right word
- 対象たいしょうno-adjectiveA common noun that really means 'target', 'object' or 'subject' — what something applies to. Its 'coverage' reading is the what-is-covered sense — whether something is covered or excluded — not a stand-alone word for coverage itself.
- nounThe direct loanword, used where the English term itself is current — media reporting, and technical fields such as software testing. Less common overall, but the natural choice when you simply mean coverage.
- 網羅率もうらりつnounCoverage as a measurable rate — how much of something is covered, expressed as a percentage. In practice it turns up chiefly in software testing, for how much of a program's code the tests exercise.
- 対象範囲たいしょうはんいnounThe range of things something applies to — scope more than coverage. You meet it in specifications, settings and documents where the applicable range is being spelled out.
- 有効範囲ゆうこうはんいnounThe area or range within which something is valid or effective — hence coverage in the spatial sense, such as the reach of a broadcast signal. Not the word for media or reporting coverage.
Choose by sense: 対象 for what something applies to or covers, 「カバレッジ」 as the direct loanword in media and technical use, 網羅率 for coverage as a measurable rate, and the two 範囲 compounds for scope or effective range.
