Mizusawa in Iwate reflects the Iwate Prefecture Kitakami River valley position in the Oshu metropolitan area, with vehicle traffic on surrounding roads and the manufacturing, agricultural, and services corridor contributing local sources. Consistent Pacific coastal and Ou Mountain breezes provide background ventilation, while the Kitakami highland topography provides variation and the area generally maintains moderate to good conditions for a major Japanese Tohoku corridor city throughout most of the year.
