Ōme's air quality benefits from its exceptional western Tokyo metropolitan Tama River valley position at the Okutama mountain gateway, with consistent mountain valley breezes from the surrounding Okutama and Chichibu highlands providing relatively clean natural ventilation. Vehicle traffic on surrounding roads and the manufacturing and residential character contribute local sources, while the mountain valley position aids natural dispersal and Ome generally maintains among the Tokyo metropolitan area's more moderately ventilated western gateway city environments throughout most of the year.
