Saruhashi (Monkey Bridge) which spans the Katsura River, located in the city of Otski in Yamanashi Prefecture, Japan, is called one of the three unusual bridges in Japan together with Kintaikyo in Yamaguchi Prefecture and Kiso-no-kakehashi in Nagano Prefecture. Because the banks of the river are so steep and high above the river, the bridge is characterized by its absence of piers and by wooden, support beams that protrude from the banks alongside.
