. The Noboribetsu Primeval Forest In 1924, the forest around Noboribetsu-Onsen Hot Springs was nationally protected and designated as the "Noboribetsu Primeval Forest". In those days, the forest comprised mainly typical gigantic trees found in south Hokkaido, such as Mongolian oak and Caistor aralia. Later, however, the forest changed much as a result of logging activities in the last years of World War II and the destructive forces of Typhoon Toyamaru in 1954. You can still find towering querus crispula trees here and there. From these, you will be able to imagine the former glory of the primeval forest.
This big rock was formed about 50000 years ago when Mt. Kuttara erupted. Heavy gravel spewed by the eruption fell around the mountaintop and ran down its slope. Pieces of the gravel piled up and melted together to form the rock.
