This is one of the all night sentos open on the outskirts of Amagasaki's red light district. It's an interesting place and there's always a few characters there. It's pretty dirty and not well taken care of however. This is by no means a beginner sento and I can't really recommend it to anyone, but crazies like me. The spring is of moderate quality and the selection of baths is not too bad. It's a good place to know if you've missed the last train, or coming home on the first. This onsen closes at 9 in the morning and opens in the afternoon.
