Hotel Keikyu Aburatsubo Kanchoso

The Hotel Keikyu Aburatsubo Kanchoso is a tranquil coastal retreat situated on the scenic tip of the Miura Peninsula. While the hotel’s exterior maintains a modest, somewhat weathered appearance reminiscent of a classic seaside motel, the facility houses a natural onsen that offers some of the most serene maritime vistas in Kanagawa. Drawing mineral-rich water from deep beneath the nearby seabed, the springs are characterized by a high salinity and a distinctively salty taste, known for their ability to retain heat and soothe the skin.

The view of Koajiro Bay from the restaurant — The view from the restaurant. This is similar to the view from the outside baths which are located below

The onsen is comprised of three main tubs: a temperature-controlled indoor bath and two open-air tubs that overlook the sparkling waters of Koajiro Bay. Among the outdoor options is a one-person “pot” jacuzzi, allowing visitors to soak in the sea breeze in relative solitude. Because of the hotel’s slightly remote location, the baths rarely experience the heavy crowds found in more central resort areas. To complete the visit, the on-site restaurant serves local Misaki Maguro (tuna), a regional specialty caught in the surrounding waters, providing a high-quality culinary experience at reasonable prices.
