We have analyzed the interaction of the air pollution gases concentration between neighboring places in Kitakyushu area by KM2O-Langevin equations theorem, which provides the causality between different time series. From the analyses on SO2, NO2 and NO gases concentrations on 100 hours basis from 1980 to 1986, we have recognized a strong causality on SO2 in 1980 and 1986, but not noticiable in other cases. We have also recognized a moderate causality on NO2 in 1986.
