Abstract
A survey has been carried out on the characteristics of unusual sea level observed along Southern Kanto coasts. There are two types of unusual sea level depending on their life times. As for unusual sea level of short life time, strong wind from northern directions and high waves at Choshi play important roles in generating sea level deviation. The deviation propagates along Southern Kanto Coasts.
On the other hand, as for longer unusual sea level, the distance of Kuroshio from the Japanese coast has something to do with the magnitude of unusual sea level deviation. When Kuroshio is near from Nojimazaki, the deviation tends to develop.
