okokok the video was just meant to be fun. Since we aren't in Japan all the time we thought it would be fun to do a video.
The obstacle course is very similar to the actual Sasuke (ninja warrior here in the states) course.Sasuke competitors have gone there to hang out and train. And amateurs occasionally compete in a contest to get onto the actual show. have gone there to rep the show. Sasuke champion Makoto Nagano did a ribbon cutting there. The ledge and salmon ladder are actually pretty hard.
