The air polution in Kagoshima city from April 1987 to March 1988 was investigated with particular emphasis to the volcanic ashfall from Mt. Sakurajima. The volcanic ash was monthly collected together with rain water at 8 locations in Kagoshima city. After the samples had been filtered, the residue was dried and weighed, and the filtrate was analyzed for SO_4^{2-}, Cl^-, and water-soluble matter as well as for pH. The average monthly ashfall at 8 locations in Kagoshima city was 146 ton･km^{-2}・month^{-1}, which value was less than that observed in the last fiscal year. The falling weights of SO_4^{2-}, Cl^-, and water-soluble matter as well as the frequency of acidic rain were generally lower than those for the last fiscal year. NO_2 air polution was measured by use of the ''Filter-badge method'', and it was proved that NO_2 concentrations observed at 8 locations in Kagoshima city were considerably lower than the value for the environmental standard.
