Last night I went to the Takeuchi Matsuri (Bamboo stick hitting festival) In this festival, the town splits into North and South, they get pretty drunk, put on some helmets and whack each other with bamboo sticks...
As if that weren't enough, after a couple rounds they light their sticks on fire.
Apparently, tradition dictates that if the North wins, there'll be a good rice harvest, and if the South wins, the price of rice will go up.
Anyways, I'm not sure who "won," but here's some pictures.
