Otaku in Japan are somehow equivalent to being geek, meaning they are tend to be bullied or looked down upon. That's why some don't admit that they are otaku because of shame. And there are certain cases of otaku becoming a hikikomori, (an example of this is in Welcome to the NHK where the male protagonist is a hikikomori) wherein they isolate themselves or withdraw themselves from society and a NEET (Not in Education, Employment or Training), where they remain jobless. How true are these cases and is it true that most of hikikomori and NEET are otakus (like Misaki Nakahara in Welcome to the NHK)? Or hikikomori and NEET people tend to become otaku (just like Tatsuhiro Sato in Welcome to the NHK)?
