Hotto Yuda is a small hot spring built in to the JR train station with the same name. It’s a unique combination of two of Japan's national hobbies: bathing and trains. The bath is not much to talk about with some nice wood siding on the tubs but there's not much to it. There are three baths going from extra hot to just warm. There's the piping for making the extra hot tub a bubble bath, but it was turned off when I went. The washing areas and spigots have seen better times and have varying pressures. Overall this bath seems very popular with the locals and tourists alike. Worth checking out for the beautiful train ride up to the station, but remember there's not much there and not many trains stop at the station each day so plan appropriately. Thankfully there is a signal light installed along the wall to give you ample warning the train will be there soon. I forgot to mention the water, it's definitely a hot spring and you can tell when getting in after a while I was hard to notice that it was spring water. After getting out it leaves the skin very smooth and soft to the touch. There is also a private family bath here for ¥1,600. The type of spring says it is sulfuric but I did not notice any sulfuric flavor or smell to the water.
