Recognizing there's a better way to survive the Polar Vortex than hurling boiling pots of water into the air, modern-day Japanese warriors took to the battlefield last weekend in Hokkaido to hurl something else -- snowballs. At each other. In a giant, sanctioned snow war.
In what's become an epic annual tournament since 1989, the game of Yukigassen (which means, "snow battle") pits opposing teams of seven against each other on a paintball-like field; each team has a mere three minutes to pellet 90 machine-made snowballs at each other. While we don't yet have shots from Saturday's battle royale, these pics from last year showcase all the frosty action.
