Yao, in the eastern part of Osaka Prefecture adjacent to Higashiosaka and the Ikoma Mountains, is an industrial city known for its traditional metal processing and manufacturing heritage, the Yao Airport — a small municipal aviation facility serving private and business aircraft — and the Yao City Museum's archaeological collections documenting the extraordinary Yayoi and Kofun period cultural heritage of the eastern Osaka plain. Yao Onsen Osaka draws on sodium and bicarbonate thermal waters from the geological resources of the eastern Osaka basin, providing restorative baths in an industrial city whose manufacturing heritage, traditional eastern Osaka corridor culture, and mountain backdrop of the Ikoma range create a practically located spa destination with easy access to both Osaka's entertainment culture and the Nara Prefecture sacred landscape via the Kintetsu railway. The Yao City Museum's ancient history collections, the Ikoma Mountain hiking trails and the Ikoma cable car ascending to the Hirakata-Ikoma highland park, and the easy Kintetsu access to Nara's UNESCO sacred landscape make Yao a conveniently located spa destination on the Osaka-Nara corridor.
