Nishiura Onsen Gamagori is a coastal hot spring resort in Gamagori, a city on the shores of Mikawa Bay in Aichi Prefecture, Japan, famous for its Takeshima Island — a small shrine island connected by a 387-meter bridge — and its role as gateway to the Mikawa Bay National Park's intricate coastline of shellfish aquaculture and winter waterbird habitats. The naturally chloride-sodium saline thermal waters carry the distinctive mineral character of Mikawa Bay's coastal geothermal zone, prized for their deeply warming and skin-softening properties suited to seaside wellness. With its traditional ryokan and kaiseki cuisine culture, Nishiura is one of the Tokai region's most beloved classic hot spring resorts, offering ocean views, fresh seafood, and mineral bathing in a genuinely Japanese coastal resort tradition.
