Nakai Onsen Kanagawa

Nakai, in the Ashigarakami district of northwestern Kanagawa Prefecture at the foot of the Tanzawa Mountains, is a small agricultural community in the Sakawa River valley whose traditional farming landscape of mandarin orange and plum orchards, the traditional farmhouse preservation, and the natural scenery of the lower Tanzawa mountain foothills create a pleasantly unhurried spa setting in the northwestern Kanagawa agricultural zone. Nakai Onsen Kanagawa draws on sodium and bicarbonate thermal waters from the geothermal resources of the Tanzawa mountain zone, offering restorative baths in a farming community whose mountain foothills setting, traditional Kanagawa agricultural landscape, and proximity to the Tanzawa-Oyama Quasi-National Park hiking network create an accessible and naturally refreshing spa destination within easy reach of the Odakyu and Gotemba rail corridors. The Tanzawa mountain hiking trails accessible from the Nakai valley, the traditional mandarin orange orchards and seasonal harvest experiences, and the Sakawa River valley cycling routes through the northwestern Kanagawa agricultural landscape create a pleasantly rural and naturally connected thermal spa setting.
