Isehara Onsen is a welcoming hot spring in Isehara city, Kanagawa Prefecture, located at the base of Mount Oyama — one of the most sacred mountains of the Kanto region, home to the ancient Oyama Shrine and the Koma-ji Temple that have attracted pilgrims for over a thousand years. The bicarbonate thermal waters are soothing and skin-beneficial, providing a restorative complement to the spiritual and physical exertion of climbing Mount Oyama's historic stone-paved approach through a cedar forest of dramatic grandeur. The onsen town's tradition of serving hikers and pilgrims descending from Oyama gives it a warm, unpretentious hospitality rooted in centuries of welcoming weary mountain travelers.
