Between naked restaurants and poo-themed cafes, Japan is home to some strange attractions. Now in an even more unprecedented move, the country is opening a "spamusement" park, hot-tub roller coaster included.

Situated in the city of Beppu, the park promises a bizarre combination of adrenaline and good hygiene. The promotional video on YouTube shows crowds of towel-clad people enjoying a hot-tub roller coaster, steam-room style gaming area, and other typical rides like carousels and Ferris wheels, but with bathtub compartments. It nearly led us to believe the "Yu-enchi" onsen (hot spring) was already a huge success, though according to the city mayor, Yasuhiro Nagano, the park isn't yet built, and will only become a reality if the video receives a million views. 

Well, the video's view count has already doubled that, leading Nagano to thank the public for their support and confirm his intentions to go through with the project. No, it's really not a joke.

While the concept is there in theory, issues still need to be worked out. A spokesman for the project, Michitaka Kubota, told the Japan Times “It’s only an image. We are still discussing safety issues, for example, whether we could actually run hot water inside a roller coaster.” A valid concern, of course, but we're keeping our fingers crossed for a positive outcome. After all, who doesn't love the idea of combining an epic roller coaster and awesome spa sesh?
