There are many Masonry Sabo Dams called Sunadome from ancient times in Fukuyama city, Kannabe town in the eastern Hiroshima prefecture.
We have comparatively little rain, but much of debris flows due to geographical features in case of long rain in this district. Before, some of these dams were reported at Journal of Japan Society of Erosion Control Engineering in 1977. Historically and structurally, we enforced investigation again in 1994 including other undiscovered dams for environmental complete equipment and regional promotion.
So we can say that Sunadome in Fukuyama Han was constructed from the period Edo for protecting human life against debris flows and floods, and original form of Sabo Dam in Japan.
