This is the most popular onsen of the area. The sign reads "kin no yu" which literally means "golden hot spring". The water does have a orange colouration to it, and feels very smooth and smells very naturey as well. There are other onsen to explore, but knowing what I've seen here, this will not have been my last visit.
