Way too simple. Almost no facilities.
You have to choose hot or lukewarm (already hot) water. You can only enter one bath for the price.
Go to Kaimonji Onsen just around the corner.
Same price and much better. And you have both included - hot and lukewarm
It's a really small onsen for a low price. The retro vibe was nice. There is only one pool in the female section while the male section has two. My boyfriend said the hot bath was unbearable so I recommend using the lukewarm one. The low rating is because of the lady who runs the place. We speak japanese and still the lady was acting like she didn't really understand us and treated us differently than japanese customers. We thanked her gratefully in the end and she didn't even care to notice. I would recommend going to a different onsen in the area if you don't want to be treated weirdly for being a foreigner.
My first onsen bath it was great feels like my body was restarted. OMG!
We went into the nuru-yu (lukewarm bath) as we prefer not to be scalded by the water. Something in between the temperature of the lukewarm and hot would have probably been perfect but it was still enjoyable. We used the bath under the stairs because the other one was way too hot. The atmosphere was quite nice although I'm not sure about the cleanliness. It was hard to tell but it seemed ok.
