The hot springs on offer at Yakushi Onsen Hatago were first discovered by pilgrims during the Edo era. The water comes from a deep vein that has naturally formed in the crust of the earth, providing consistent heat through geothermal activity. A live video feed at the entrance to the public baths takes you to the source of the hot water as it seeps out of the earth at 42.8 degrees Celsius. The onsen offers private and public baths, as well as an ashiyu (foot bath).
Three onsens are available in this public facility, which is open around the clock every day. In addition to the bath comprised of 100 percent onsen water, there is also a Neyu bath in which you can lie back and a Germanium bath that is good for perspiration.
These two private facilities feature a wooden (hinoki) bathtub and jacuzzi, allowing visitors to enjoy a view of river valley in complete privacy.
This onsen features a large wooden bathtub, which is ideal for families and large groups.
Satono-yu is an onsen infused with herbs collected from the surrounding area. This bath possesses amazing restorative powers and is known to help treat a wide range of ailments.
Takimino-yu is a rotenburo (outside onsen) that offers a spectacular view over the facing valley as well as a waterfall located nearby. In autumn, the trees erupt into a riot of color that is sure to turn your simple bath into a particularly memorable experience.
