Chuan Peng Wenquan — 'Roc Wing Hot Spring' — is a geothermal spring in China, its name invoking the legendary Roc — the immense mythological bird of Chinese and Persian tradition — whose vast wings spread across the sky in the imaginative geography of Chinese classical mythology. The naming of Chinese hot springs after mythological and cosmological figures reflects the deep integration of thermal spring culture into the broader symbolic and imaginative life of Chinese civilisation, where the warm waters emerging from the earth were understood as expressions of the same cosmic energies that animated the great figures of myth and legend. The spring provides warm, naturally mineralised geothermal water in an authentically mythologically named Chinese setting.
Insider tip — Situated at the northern tip of Kyushu island near Kitakyushu's industrial coast, this onsen draws from a geothermal system linking the broader Beppu-Shimabara graben hydrothermal field. The water is clear with a mild saline-thermal character, reflecting sodium-chloride mineral enrichment at depth. Despite the industrial surroundings, the bathing experience is restorative, and the facility serves local steelworkers as well as visitors. The Kanmon Strait connecting Kyushu and Honshu is visible from nearby viewpoints.
