A dreamlike waterfall， ”Usogui No Taki” in the middle of valley， is located in the deep place between mountains， the upstream of Ono River in the Tsuru District， Takamori Cho.

This is an interesting waterfall which subsoil water streams into between layers of lava flowing out from the Aso great eruption about 90000 years ago， and gushes from rock walls. The maximum drop is 30m. The best part is that water strongly falls down with water splash from a cliff.

The pavement is built; however， guides accompanying you are required because there are some rough spots you need to pass with a steep slope， ropes， and ladders.
