The authors studied the air pollution of Kagoshima City from April 1977 to March 1978 on the falling dust and the content of the sulfur oxide, for five years running. The amount of falling dust was very large. The average value of the amounts at the 12 measuring points was 128.1ton/km^2 ･ month, and that value was about 35% increased comparing for that of the foregoing one year. That value is extremely large comparing for the value of other city of Japan (10-20ton/km^2 ･ month). Most of the falling dust was formed from the falling ash of the eruption of Mt. Sakurajima, and somecounter-measure must be take quickly.Average of the sulfur oxide contents at the 12 measuring points was 0.25mg/100cm^2 ･ day, that was equal to that of the foregoing one year.
