Another secret bath far up in the mountains across from Kansai Airport. It's a bus ride up the mountain from Hineno staiton. From the bus stop you have to walk along the narrow mountain road about 150 yards to the entrance to this hidden spot. In Inunakiyama Onsen there are many hot spring ryokan but only Yama no Yu allows day use. The building is stoic and industural looking to say the least. Approaching it, I thought I was going to a factory or wearhouse. The open and price sign assured me I was in the right place however. I think I went through the rear entrance actually. There might be another way in if you walk further up the road. After paying the attendant on the top floor then going back down to the bottom floor to the baths. Only one bath here and a few faucets. There are no jets or anything--this place is about the water. The water is just full of yu no hana which are minerals and what not that is coming up from the earth with the spring water. It felt great and it has that unique onsen smell to it. The view of the river from the bath was also nice. This is a great amazing hidden bath that any fan needs to check out.
