1440-Sayama Pond Dam
Sayama Pond Dam is the oldest earth dam in Japan, a reservoir that has been passed down from generation to generation since the 7th century, and now serves not only as an earth dam for farmers, but also to protect the lives and property of citizens, and has been transformed into a place for birds and citizens to relax. It will be passed on to the next generation for another 100 to 200 years. / Earth dam /18.5m
