Naguri Onsen

Naguri Onsen in the Hanno/Naguri area of Saitama Prefecture offers simple alkaline thermal waters within forested mountain terrain that provides one of the most accessible genuine woodland thermal spring experiences for residents of the Tokyo metropolitan area—a day-trip destination where the cedar and mixed-forest landscape of Saitama's western highlands creates a convincing natural retreat from the urban environment despite its proximity to Japan's largest city. The Naguri area's forests and the Naguri River valley provide the natural setting for a thermal spring whose simple alkaline character reflects the moderate geological thermal activity of Saitama's highland volcanic heritage at the northeastern extremity of the Japanese Alps. Simple mineral waters in a forest valley accessible from Tokyo make Naguri Onsen a valued everyday escape for metropolitan residents seeking the minimal thermal spring experience of genuine forest immersion combined with mineral bathing.
