Koganeyu is also in Mori Machi, just like Mori no Yu and Morimachi Dream Tennen Onsen. It is a small onsen with two baths: a hot one and a very hot one. You don't see these small local baths so much in Oita, so it was a welcome change.
Rather than an onsen, the place looks like someone's home (apart from the vending machine).
The lockers have poems on them.
