Mom is in town from the U.S. and we took her to the standard Beppu tourist trap, "Jigoku Meguri." That is where you walk around all the bubbling hells saying "ooh" and "Ahh" and trying not to pay 3 bucks for ice cream. Several have foot baths, like Oni-bozu Jigoku featured here.
And these foot baths count toward our 88 onsen goal. Entrance fees are 400 yen for most jigoku or you buy a book of 8 tickets for 2000 yen. Seniors got in free on April 1 for the Hot Spring festival
And after a lot of walking, these foot baths sure feel good
