Zama's air quality reflects the Kanagawa Prefecture Sagami River valley position adjacent to Camp Zama US Army base, with the military base's operations and vehicle traffic on surrounding roads generating elevated NOₓ alongside the surrounding manufacturing and residential character. The Sagami valley provides limited ventilation, while the military operations represent the most distinctive local emission source and the broader Tokyo-Yokohama metropolitan regional background influences readings throughout most of the year.
