Spectacular open-air baths overlooking the sea and an exceptional hot spring of heat
JFA Dream Field Makuhari Onsen Yurakuno-Sato is a day-use hot spring facility in Mihama Ward, Chiba City, Chiba Prefecture. Its greatest attraction is the panoramic open-air bath with sweeping views of the blue sky and the sea. The rich, highly saline chloride spring that gushes up from deep underground is known as the hot spring of heat, and it warms you to the core while letting you feel the sea breeze. After working up a good sweat in the authentic sauna equipped with auto löyly, you can cool down comfortably in the cold plunge bath. The facility also features a dreamlike nano-mist attraction that makes you feel as if you are inside a cloud, a variety of bedrock bathing areas, and a high-concentration carbonated spring. It is the perfect place to refresh after sports or simply forget about everyday life and enjoy the ultimate relaxation while gazing out at the sea.

A rich chloride spring that has been matured from ancient seawater pumped up from deep underground. In the open and airy panoramic open-air bath with views of the sea, you can enjoy an exquisite bathing experience while gazing at the gentle sound of the waves and the setting sun. Known as the hot spring of heat for its excellent warming effect and resistance to cooling off, it gently envelops the entire body and melts away daily fatigue from deep within.

An authentic sauna equipped with auto löyly that operates regularly. When water is poured onto the heated sauna stones, rich steam and powerful waves of heat spread throughout the room, gently enveloping your whole body. By thoroughly promoting perspiration, it helps boost metabolism and provides a refreshing reset that feels as if it washes away accumulated waste from both body and mind.

A cold plunge bath that gently tightens a body thoroughly warmed by the sauna. As you slowly immerse your overheated hands and feet in the cool water, the blood vessels throughout your body contract pleasantly, guiding you into a deeply relaxed state. After a refreshing cooldown, you can smoothly move on to the outdoor bathing space where you can feel the sea breeze and enjoy blissful totonou time to the fullest.

It features a wide range of facilities, including the dreamlike nano-mist attraction Genmu, which makes you feel as if you are inside a cloud, Pulgama, which warms you from the core with far-infrared heat from a fire kiln, and bedrock bathing laid with eight kinds of mineral stones.
