Our first onsen on our Beppu challenge was Rakurakuen.
Located in the heart of Kannawa, it took me 3 tries to find it. It happens to be right behind the Everyone convenience store on the Kannawa-sen road.
It was rustic to say the least, but I (I think Jude was too) was ready to do Beppu's onsens, or at least 88 of them.
Ok, this place was crusty. To top it off 2 tattooed yakuza came in and it was slightly uncomfortable. The outdoor bath was a nice temperature and Jude seemed to enjoy it. There was a nice old man there too.
There was a 蒸し湯 sauna too, but I didn't try it.
Better luck next time.
