Itō's air quality benefits from its exceptional Shizuoka Prefecture Ito Bay and Pacific Ocean coastal position on the Izu Peninsula, with consistent Pacific maritime breezes providing reliable ventilation along this famous hot spring and resort coast. Vehicle traffic on surrounding roads and the onsen tourism, mandarin, and services corridor contribute modest local sources, while the outstanding Pacific coastal exposure and the volcanic Izu highlands rising inland generally maintain Itō among Japan's more moderately ventilated resort coastal cities.

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
