1. Imagine being this guy. There you are, fast asleep.
2. Last night you passed out drunk in a cabin at the foot of Mt. Fuji.
3. Unbeknown to you, there are a couple of sadistic maniacs in a nearby cabin who plan to wake you up in the most terrifying way imaginable.
4. The first thing you’re aware of is a loud bang, and the blinding flash of fireworks.
5. Then you are catapulted 150 feet into the air.
7. Your reaction would probably be… well, this, pretty much.
8. Meanwhile, everyone else’s reaction would be more like this.
9. Well done, Japanese TV people. Once again you have proved you are the kings of the massively dangerous and ill-advised prank.
