Toba Onsen Mie is a coastal thermal spa in Toba, a scenic port city in Mie Prefecture, Japan, internationally celebrated as the birthplace of cultured pearl farming pioneered by Mikimoto Kōkichi in 1893 — a revolutionary achievement that transformed the global jewelry industry — and home to the famous Toba Aquarium and the traditional Ama pearl-diving women of Ise Bay. The naturally chloride-saline thermal waters reflect the maritime mineral character of this pearl-farming coastal city, valued for their skin-moisturizing and deeply warming properties that contrast with the cool ocean environment the Ama divers brave daily. Combining the unique cultural heritage of pearl cultivation, exceptional seafood culture, and the bathing hospitality of Toba's ryokan district, this onsen offers a distinctively maritime thermal experience on the gateway to the sacred Ise-Shima National Park.
