Abstract
　To explore a change of typhoon disasters in the area around Ise Bay and its feature, some investigations are made on the relation between the destructive power of l30-typhoons which attacked the area for seventy five years from l9l2 to 1986 and the damages caused by the typhoons in both prefectures of Aichi and Mie. It is revealed that although the typhoons accompanying storm surge are very dangerous for both the prefectures, countermeasures for typhoon disaster prevention which have been provided since l960 are fairly effective against the attack of such the typhoons and succeed in decreasing the damages. While, it is pointed out that the rate of the damages to the power of the typhoons which attacked both the prefectures after l960 rather exceeds that before l959 and typhoon disasters are changing in quality since 1960.
