These publications classify distinct groups including anime, manga, camera, automobile, idol and electronics otaku.The economic impact of otaku has been estimated to be as high as ¥2 trillion ( billion). This word is often used metaphorically, as an honorific second-person pronoun. For example, early in the anime Macross, first aired in 1982, the characters Hikaru Ichijyo and Lynn Minmay use the term this way to address one another, until they get to know each other better.However, a different claim points to a 1981 Variety magazine essay.Miyazaki, who randomly chose and murdered four girls, had a collection of 5,763 video tapes, some containing anime and slasher films that were found interspersed with videos and pictures of his victims.Otaku subculture is a central theme of various anime and manga works, documentaries and academic research.The subculture began in the 1980s as changing social mentalities and the nurturing of otaku traits by Japanese schools combined with the resignation of such individuals to become social outcasts.Otaku may be used as a pejorative; its negativity stems from the stereotypical view of otaku and the media's reporting on Tsutomu Miyazaki, "The Otaku Murderer", in 1989.
Other institutions have split it further or focus on a single otaku interest.
Because this misuse indicated social awkwardness, Nakamori chose the word itself to label the fans.
