Nasushiobara's air quality benefits from its exceptional Tochigi Prefecture northern Nasu highland position adjacent to the famous Nasu volcanic highland resort, with consistent mountain highland winds providing reliable natural ventilation. Vehicle traffic on surrounding roads and the resort tourism, dairy, and manufacturing corridor contribute local sources, while the outstanding highland position and the clean Nasu volcanic backdrop generally maintain Nasushiobara among Tochigi's more pleasantly ventilated highland resort city environments throughout most of the year.
