Kamuiwakka Falls is a cascading hot spring waterfall on the Kamuiwakka River within the remote Shiretoko National Park in eastern Hokkaido, a UNESCO World Heritage site where volcanic activity heats the mountain stream to create warm carbonated natural pools amid pristine wilderness. Visitors can soak in naturally heated river water surrounded by virgin Shiretoko forest in an outdoor onsen adventure celebrated as one of Japan's most extraordinary wild bathing experiences. The Ainu name Kamuiwakka, meaning water of the gods, reflects the indigenous reverence for this rare phenomenon where a living hot spring river flows freely through one of Earth's most biodiverse temperate coastal ecosystems.
