Hot Spring & Bath Information

Futago no Yu Onsen

TypeNatural Hot Spring

The only iron chloride spring in Miyagi Prefecture. Known for its rich iron and salt content, the salt film envelops the skin, providing high heat retention. Bathing warms the body from the core, with warmth lasting long after. The tea-brown colored water is rich in iron, expected to be effective for skin and gynecological diseases. There are two bath areas: 'Sakura' with a large cypress bath and open-air bath, and 'Kashiwa' with a large stone bath and open-air bath, alternating weekly between men and women. Each offers a different ambiance, allowing you to enjoy the warmth of cypress and the solidity of stone. After aligning your body with the sauna and source cold plunge bath, soaking in this hot spring deeply relieves fatigue.
