The recent Amusement Operator Union arcade expo wasn't only about dancing girls and giant robots, it was also about figurines and prizes.

Every February, the Amusement Operator Union holds its annual trade show. Much like the Tokyo Game Show, it's held at Makuhari Messe—right outside of Tokyo—and also much like TGS, it showcases all of Japan's upcoming games—only this time in arcade form.

Last weekend, Kotaku East scoured the Amusement Operators Union (AOU) trade show for the craziest game coming to Japanese arcades in 2012. And what we found is a game as fun and simple as it is crazy.

The recent The Arcade Operators Union Entertainment Expo featured a slew of prize machines — and things that can be won from said prize machines.
