Ōkina otomodachi (大きなお友達) is a Japanese phrase that literally means "a big friend" or "an adult friend". Japanese otaku use it to describe themselves as adult fans of an anime, a manga, or a TV show that is originally aimed at children. Note that a parent who watches such a show with his or her children is not considered as an ōkina otomodachi. An ōkina otomodachi is not a parent who buys anime DVDs for his or her children to watch. Ōkina otomodachi are those who buy children’s anime for themselves. Also, if the work is obviously aimed at adults, a fan of it is not an ōkina otomodachi. Hence ōkina otomodachi and otaku are different concepts.
