Regardless of training, that's a very hard throw. Even if these Japanese supermen could hit the top of the beaker 9 out of 10 it's still a 1 in 100 chance of them all hitting the target.
Assume 10 minutes per shot (having done TV work I'd say that's a very optimistic estimate!) and you're looking at nearly 17 hours to get it. And then you'd probably have to redo it because the tracking shot wasn't quite in sync with the throws!
To misquote James Randi - if they're doing this for real, then they're doing it the hard way.
