Matsuo Pond

 is a pond in Gifu, Gifu Prefecture, Japan. It is located at the southern base of Mount Dodo, the city's tallest mountain. The area around the lake is known as the Hagi Falls Nature Park (萩の滝自然公園 "Hagi-no-taki Shizen Kōen"). The park is very popular in the fall when the leaves are changing color.
