| Kannawa Onsen Legends & Origins | Kannawa, one of Beppu's “eight hot springs” (Beppu Hattō), is known for jigoku-mushi — cooking food by steaming it directly in geothermal vent steam. In its Edo-period hot-spring lodges, long-term guests staying for the cure would cook their own meals in inns equipped with “hell-steaming” kettles, using roughly 98°C spring steam straight from the ground — a self-catering bathing culture unique to this place, still practiced today.
