About this facility

A day-use natural hot spring in Toyokawa, Aichi Prefecture. Alongside a smooth saline indoor bath, it offers a carbonated bath, tsuboyu (single-person pot baths), and an open-air bath. There are two saunas, a high-temperature dry room and an auto-loyly room (water automatically poured on hot stones), plus a choice of two cold plunges, one around 10°C and one around 15°C. You can cool off in the outdoor air on reclining chairs in the open-air area, and the barrier-free layout includes an elevator. The "Uma no Se" dining area, value set meals, and soft-serve ice cream are also available. Open 10:00–22:00, closed Wednesdays, 700 yen for adults.
