Broadcasting stations in Japan often create TV programs without ethics, because they are devoted to getting more views. So, they often broadcast TV programs which cause much laughter, but anger at the same time.
This TV show is a typical one. Many viewers laugh at unexpected and cute behavior of the performing children. On the other hand, imagine if you are told to perform at the same age as them. You must feel isolated and sadness.
