Tokyo has dramatically improved its air quality since the 1970s through strict emissions controls. The city still faces occasional photochemical smog during hot summers and PM2.5 transport from continental Asia. Tokyo's extensive park system, including the Imperial Palace grounds and Yoyogi Park, provides cleaner running environments.
Tokyo typically sees AQI values between 25 and 55. Spring can bring transboundary PM2.5 from mainland Asia, and summer heat occasionally triggers photochemical ozone alerts.
Autumn offers the best combination of cool temperatures and clean air. Morning runs around the Imperial Palace or through Yoyogi Park are popular among Tokyo's running community. Check conditions during spring dust season.
