Yukunkako, also called K-A Crater, is the largest crater formed around Mount Konpira during Mount Usu’s 2000 eruption. A tuff cone of accumulated ash and rock fragments surrounds the crater, which holds emerald-green water in summer. The walking trail reaches the safety rope at the rim, offering views into the crater and toward Lake Toya and Mount Yotei.
