For the video on the left!
TV Special in 2007: Cut down 1000 rolled up tatami mats in 36m 04s
2008: got a Guinness World Record when he achieved 7 cuts at suegiri (cutting a single tatami mat several times without it falling over or not cutting all the way through). He attempts to beat the record in the video.
last challenge: cutting a junior baseball ball (i.e. a rubber one) flying towards him at 120km/h while unsheathing and cutting in the same single motion.
Sometimes, people have the most insane skillz, so here are a few videos of that. For sake of understanding, I’ve added the most important key points next to the first video since it didn’t have notes or subs.
