Imarichō-kō's air quality reflects the Saga Prefecture Imari Bay and East China Sea coastal position adjacent to the famous Imari and Arita porcelain corridor, with vehicle traffic on surrounding roads and the Imari porcelain — Japan's most internationally renowned historical export ware — and manufacturing corridor contributing distinctive ceramic kiln dust alongside primary vehicle sources. Consistent East China Sea maritime breezes provide coastal ventilation, while the porcelain kilns' distinctive emissions represent Imari's most culturally unique air quality characteristic throughout the year.
