上空

• ピンイン: shàng kōng
• 漢字の分解: 上 = above/upper; 空 = 穴 (cave/hollow radical) + 工 (work/phonetic) = empty space/sky — 上空: the empty sky above a specific place; airspace

意味

（〜の）上空

Used to describe the airspace or sky directly above a named location, country, body of water, or structure. Commonly appears in aviation, military, weather, and news contexts. Contrast with 天空 (the sky in general) — 上空 is relational and location-specific, always implying 'above X'.
