This is Kayamiyama Onsen, a white walled hot spring facility sitting at the foot of Mt. Kagami. Suffused with iron and low levels of radon, the hot natural spring water is drawn up from a depth of 1,600 meters below. Enjoy a fresh seafood meal while watching the fish in their tank swim about. Kagamiyama Onsen is the perfect place to round out your trip to Karatsu.

Come experience the famed health benefits of resting your weary bones in a Japanese Hot Spring.
