10 Most Unique Sports You Won't Believe Exist

Oh, this bit looks painful. Which bit? Every bit. When a sport has a specific position known as 'ninja' (the fellow at the top of the pole kicking his buddies), you know there may be a bit of violence involved.

The game is played in Japanese schools on sports days but the most well known of these events is played specifically by cadets of the National Defence Academy of Japan, where 150 (one hundred and fifty, this is not a typo) army cadets have a go at trying to keep a pole up or take it down depending on what team they happen to be on that day.

The game, if one can call it that, resembles some kind of horror king-of-the-hill/capture the flag/battle royal where every sort of defensive and offensive technique is not only permitted, but encouraged. The amazing thing is after a round of head stomping everyone just carries on - no hurt feelings, just hurt scalps. It's worth a watch but probably not if you're a bit squeamish at people being full-on booted in the face.
