Flash floods occurred and killed people in Japan in 2006. We found several cases where meteorological radars had observed localized strong rainfall areas in the upper streams of the rivers where the flash floods had occurred. However, no rainfall had been observed in the down streams. Two types of flash floods were observed. One is characterized by its abrupt rise in the water stage just like a debris flow. The other does not appear with such a sudden water rise but as rapid as 50-100 cm per several tens minutes. The field surveys revealed that these two types might be caused differently.
