Otaku used to be negative word. If you are said as Oktaku, it was something you are looked down. You are not outspoken person not active type. Oktaku seeks for very minor sub-culture such as anime and comics.
But when those anime and comics became major culture in Japan from sub-culture, Otaku is no longer
word of negative term. Now Maid Caf? is also well known.
If you are Otaku in some area, you are very good at some special skill.
This trend is strengthen by having new Prime Minister in Japan, Mr. Taro Also who is self claimed Okaku.
