Yorii, a small town in the Chichibu region of western Saitama Prefecture on the Arakawa River, sits at the transition between the flat Kanto Plain and the forested mountains of the Outer Chichibu Range, surrounded by limestone quarries, cement plants, and the natural beauty of the Arakawa valley carved through Paleozoic geology. Yorii Onsen Saitama draws on sodium and bicarbonate thermal waters from the geothermal resources of the western Saitama mountain zone, providing relaxing baths in a pleasant rural setting that bridges the agricultural flatlands of the Kanto and the mountain spa country of Chichibu. The nearby Nagatoro river rapids, Chichibu's nationally celebrated night festival with spectacular fireworks, and the ancient Chichibu Pilgrimage of 34 Kannon temples winding through the forested Chichibu basin create an exceptionally rich cultural and natural context for thermal bathing in western Saitama.
