Sandachō in Hyogo reflects the Hyogo Prefecture central corridor position adjacent to the Chugoku Mountains, with vehicle traffic on surrounding roads and the agricultural and light manufacturing character contributing local sources. Consistent Seto Inland Sea influenced breezes provide background ventilation, while the surrounding mountain topography creates variation and the area generally maintains moderate Hyogo Prefecture inland corridor readings throughout most of the year.
