query: What is the definition of otaku in Japanese culture?
answer: Otaku is a Japanese term for people with obsessive interests, originally derived from a term for "another's house or family."  In the 1990s, it became pejorative, implying social ineptitude, but in the 2000s, it was reclaimed by fans and is now often used to refer to anime and manga fans.
