A stone monument marks the highest point on National Route 292. Looking down from the parking area where the monument sits at the high wetlands of Yoshigadaira that spread out below, one can fully appreciate the grandeur of nature—the early summer cotton grass in full bloom or the vibrant leaves of the Japanese rowan with yellow Erman’s birch in the fall.
In May 2015, the area was officially registered as a Ramsar Convention wetland under the name Yoshigadaira Wetlands. The convention works to conserve precious wetlands worldwide.
