I guess it is an appropriate way to teach children the problem of the nuclear plant. Any difficult words cannot be found in the video and it is easy for kids to understand the circumstance we are facing. There is a certain difference between Gempatsu-kun and Nuclear boy videos.
The latter one looks scary for kids in some way. For example, the depict of medicine makes kids feel nervous about the medicine. It looks like the doctors force the baby to take medicines. Kids may think they will experience the same in the future.
From another point of view, I am wondering who made the video. The video tells us that nuclear plant is safe and there is little possibility of tragedy. I think it is inappropriate to teach children that it is safe and we should rely on the nuclear plant. It should be stopped and we must substitute some other power generating sources for it.
