A friend showed me this video. In the video the Japanese guy, from a distance, waves his hands around and puts to sleep, respectively, a herd of alpaca and a herd of bison. The owners of the animals both say it's unprecedented behaviour. The chaps name is Kanzawa Sensei. At 1:18 he explains that he "puts his fingers together" and that an "exchange of chi" takes place which can, he says, "put any animal to sleep." The host of the show tests this by taking him to two ranches. At the first, he demonstrates his ability on a herd of about a dozen alpaca. One by one, they lie down on the ground. The owner of the ranch, Cecilia Secka, describes their behaviour as "not normal" and "very surprising." At the second ranch, he does the same thing with a herd of bison, in front of owner Frank Donato and veterinarian Dr Frank McEwan. They are initially skeptical, and are quoted as saying that they have "never seen bison sit down when there is a human in their pen." Naturally, one by one, they all lie down. Up until this point, it looks like Kanzawa is doing his thing from a distance of a few hundred feet. However, after they all lie down, he walks right up to the dozing herd. "I'm getting a little nervy here," Donato says, "I've owned these animals for fifteen years, but I've never been as close as he's been." (8:18) Both the vet and the ranch owner, as well as the presenter of the show (Stan Lee's Superhumans) are "dumbfounded" and at a loss to explain what has happened. NOTE: It doesn't much look to me like most of the animals are actually asleep, but they do all sit down, lie down, lay their heads down, and appear absolutely docile.
