If combining the relaxation of taking an onsen bath with the heart-stopping excitement of a water park sounds like your idea of a great time, then pay a visit to Spa World – the place that does both. Inside you’ll find a variety of themed baths, a lazy floating river, and a mega waterslide. Equal parts rejuvenating, bizarre and adorably kitsch, it’s definitely worth a visit for those wanting a more unique bathing experience.Minoo Onsen Spa Garden
