採光 combines 採 (to gather) and 光 (light) — literally "gathering light."

- 採光がいい/わるい — good/poor natural lighting
- 採光を確保する — to secure natural lighting
- 採光窓 — window for natural lighting
In Japanese building regulations, residential rooms must meet minimum 採光 standards. Real estate listings frequently mention 採光 as a selling point, especially for south-facing rooms (南向き).
