Etymology of curtilage
According to a conclusion today, the first people who used the word "otaku" were young masters from Keio University. They are fanatical sci-fi fans, and some of them once worked in an otaku animation company called studio nue, and produced the animation "Time and Space Fortress" which was highly praised by otaku, and achieved great success.
In A.D. 1982, they were the objects that all otaku yearned for. They are worshipped at sci-fi conferences and call each other otaku in front of fans, so there is no reason why other otaku should not imitate them. Moreover, they also let the characters in their own animation "fortress of time and space" call each other "otaku".
Taking studio nue's otaku and his work Fort of Time and Space as an opportunity, the name "otaku" spread among otaku in the blink of an eye. Even the novice who participated in the fan story meeting called comike began to call themselves "otaku" and "otaku". At the same time, people who call each other "otaku" are called otaku, which is indiscriminate and discriminatory.
So at this time, science fiction fans no longer call each other otaku. The word "otaku" first became a discriminatory language among otaku.
In fact, it took several years from using the title of Imperial House to being known to the general public. Later, the word "otaku" was misunderstood as "someone who has been staying at home" and spread widely. Probably because it coincides with the image of "house" as an in door. So there is such a misunderstanding: guys who like animation, comics and games have been squatting at home, gloomy and unsociable losers. As a result, the original social element of "addressing is used to avoid being rude to people who meet for the first time" was somehow abandoned.
