Genpatsu kun and nuclear boy

I think the video genpatsu-kun and nuclear boy are easy to understand. Since its target audience was children, I don't think that there was any problem with the characters. People in another country might find it a little bit disturbing but last week me and mina saw a kanji book that is called "unko", it made me think that maybe it is really an effective way for japanese kids to have interest and not be bored with the topic of nuclear issues. The japanese and the englsih version shared a similar theme. The japanese version was simple while the english version was a little bit realistic.
