Lake Rausu is a freshwater lake located at the foot of Mount Chisei Betsudake on the Shiretoko Peninsula. With an altitude of 740 meters, a circumference of about 4 kilometers, and a maximum water depth of about 2 meters, it is the largest lake in Shiretoko National Park.
The area was obscured by trees and contained bear dens, so it was once known as an imaginary lake that no one could approach. However, the mountain climbing road has been repaired and is open from June to October, so the general public can use it.
In addition to Lake Rausu, there are five marshes (Ichinonuma ~ Gononuma) and the Meiri Lookout, where you can enjoy various beautiful scenery, such as snow in spring, fresh green in summer and red leaves in autumn.
*Unfortunately, there is no road leading to Ichinuma, so you can see Ninomuma to Gononuma along the hiking trail. Free admission.
