Roller coasters, cable cars and Ferris wheels are typical rides at amusement parks, but the city of Beppu, Oita Prefecture, is mixing the excitement with a natural attraction — its famous hot springs.

In a now-viral promotional video uploaded Monday on YouTube, performers ride a roller coaster and other attractions sitting waist-deep in a hot spring.

The city calls it a spa amusement park project, dubbed "spamusement," which would become a reality if the video gains more than 1 million views, a mark reached on Thursday.
