Irago Onsen Tahara is a hot spring facility at the tip of the Atsumi Peninsula in Tahara, a city at the southern end of Aichi Prefecture, Japan, a scenic headland projecting into the Pacific Ocean between Mikawa Bay and the Enshūnada Sea, known for its Cape Irago lighthouse, windmill farms, and the important migratory bird corridor used by hawks crossing to the Japanese mainland during autumn migration. The naturally chloride-saline spring waters are valued for their warming, circulation-stimulating properties, offering a deeply restorative soak at the windswept peninsula's tip with the sound of Pacific waves nearby. Combining a dramatic oceanic headland setting, birdwatching and lighthouse heritage, and genuine coastal hot spring bathing, Irago Onsen offers one of Aichi's most atmospherically memorable thermal experiences.
