Okay, watch this. Maybe I'm late to the party, as this seems to be reaching viral video status, but better late than never. The sport is called Botaoshi, and even though I have no idea what's happening for the first half of it, I want to play it:
Literally meaning (apparently) Pole-pull down, according to Peter C. Smith's Fist from the Sky: Japan's Dive-Bomber Ace of World War II, Botaoshi is a Japanese Naval sport where two opposing teams [of possibly 75 a side] attempted to protect their respective flags placed atop a pole. Obviously, the game has replaced the flag with, well, a human being. (Though the pole has yet to become a Pole)
The aggression of North American football, the rule confusion of Aussie Rules Football (though the OAFL's High Park Demons are currently at 2-0), and the mayhem of WWE Royal Rumbles, Botaoshi should be a surefire hit for North Americans into alternative sports who have long grown tired of Ultimate Frisbee and Unicycles.
So what do you say? All we need to do is get two poles and 150 people to the park this weekend.
Should be easy. Start Bataoshi!
