A hot spring inn known for its spectacular open-air bath with beautiful sunsets over Mangokuura and sweeping ocean views
Miyagi Onagawa Town
"Onagawa Onsen Hanayubi" is a hot spring inn in Onagawa, Oshika District, Miyagi Prefecture, facing Mangokuura Bay. Its pride and joy is the spectacular observation open-air bath, where you can take in a sweeping view of the ocean and watch the beautiful sunset sink into Mangokuura. In the open-air bath, you can fully enjoy Onagawa Onsen’s calcium-sodium chloride spring, whose rich mineral content gently soothes the fatigue of travel. A spacious large public bath is also available, allowing you to spend a quiet, restorative moment with a clear mind while enjoying the dynamic coastal beauty of Sanriku and fresh seafood from the sea.
TypeNatural Hot Spring
An observation open-air bath with a breathtaking view over Mangokuura Bay. It uses Onagawa Onsen’s calcium-sodium chloride spring, and the salt content wraps the skin like a veil, providing excellent heat-retention and moisturizing effects. At dusk, you can admire the beautiful sunset sinking into Mangokuura, and at night, you can fully enjoy a luxurious hot spring bath while feeling the star-filled sky and the gentle ripples of the quiet sea.
TypeSpecialty Bath
A spacious indoor public bath. The tub can comfortably accommodate 15 to 20 people at once, and the large windows offer a view of the calm seascape of Mangokuura. The indoor bath uses heated water, not hot spring water, but it provides a clean and relaxed space where you can slowly unwind from the fatigue of travel.
