Yo-yoing is about more than just "Walk the Dog"—at least at the professional level. Kuma Films went to Osaka, Japan to hang out with yo-yo professional Ryo Yamashita, who demonstrated some of his tricks on camera. While the resulting video is good inspiration for wannabe yo-yo masters—and good eye candy for the rest of us—a few of Yamashita's moves look too mind-boggling (and even dangerous) to ever consider trying at home.
