Okinawa Nago Thermal is located in Nago City, Okinawa Prefecture, on the northern part of Okinawa's main island where the Ocean Expo Park and the Churaumi Aquarium — featuring the world's second-largest aquarium tank, home to whale sharks, manta rays, and thousands of tropical marine species — create one of Japan's most visited marine nature destinations amid the extraordinary subtropical marine environment of the Okinawan coral seas. The siliceous thermal waters here complement a city at the gateway to the northern Okinawa (Yanbaru) wilderness — a subtropical forest designated as a UNESCO World Natural Heritage Site for its extraordinary endemic biodiversity, including the Okinawa rail, the Okinawa woodpecker, and hundreds of plant species found nowhere else on Earth. Bathing at Okinawa Nago Thermal combines mineral spring wellness with access to both the world-class marine life of Churaumi Aquarium and the extraordinary endemic biodiversity of the UNESCO-protected Yanbaru forest, making it a complete natural heritage wellness destination in northern Okinawa.

Insider tip — Nago sits at the base of the Motobu Peninsula in northern Okinawa, surrounded by subtropical forest and bordered by Nago Bay. Thermal spa facilities here tap silica-rich groundwater heated by geothermal gradients beneath the Ryukyu limestone platform. The northern Okinawa coast is quieter and greener than the resort strip south of Naha, making Nago a genuine retreat.
