Izarigawa Dam Free Space (Eniwa City) is an open place like a park built in front of the high concrete dam. Sometimes, visitors can see water spilling over from the artificial lake, which is called Eniwa Lake. Visitors can walk on the top of the high concrete structure, allowing them to take in a panoramic view of the lake. In addition, there is a dam office where museum facilities can be enjoyed. People can learn of the nature around the dam and lake. Moreover, next to this Free Space, there is a different park which is famous for cherry blossoms.
