What does お宅 Otaku mean?

Otaku can name a person intensely absorbed in an interest. The same Japanese form, お宅, also has ordinary respectful uses for someone's house or household and can address another person.

The characters and the change of use

お is a respectful prefix and 宅 refers to a house. Shogakukan's dictionaries separate the home and household senses, the form of address and the specialist-fan sense. Reading the spelling alone as your house does not explain every occurrence.

The selected Nihon Kokugo Daijiten entry cites Akio Nakamori's June 1983 Manga Burikko column, Otaku no Kenkyu, as an example of naming a type of fan. Daijisen describes the early fan use as somewhat disparaging and connects it with the address fans used among themselves. The historical example supplies a checkable reference; it does not mean Nakamori invented the older household word.

An interest is not a diagnosis

The dictionary's specialist sense does not require the interest to be anime. Anime otaku is one compound specifying what the person follows. The distinction matters: a fan label can describe an interest without supplying a reliable account of someone's character, health or social life.

A story may portray a character as isolated, knowledgeable or embarrassed about a hobby. Those are separate features of the portrayal. The label alone cannot establish all three. An interpretation needs what that character does and says, rather than a diagnosis imported from a stereotype.

Disparagement and self-description

The dictionary's note about early disparagement is narrower than saying that every Japanese use remains an insult. Whether a particular occurrence is dismissive or a chosen identity requires the speaker and context. A blanket contrast in which English is always affectionate and Japanese is always hostile is too strong.

Someone claiming a label and someone applying it to another person can be doing different things. Even a shared interest does not make those acts equivalent. The useful question is what the speaker is accepting or criticizing, not whether a nationality supposedly guarantees the tone.

What an anime translation needs

Fan, enthusiast, geek and otaku each bring a different emphasis in English. Keeping the loanword can preserve the reference to a fandom identity, but it leaves the surrounding scene responsible for explaining the attitude. A translation that chooses geek makes a different interpretive choice; the dictionary alone does not decide which fits a particular performance.

This page checks the lexical senses and the cited historical example. It does not establish that a hobby causes criminal behavior, or that one label describes all Japanese or English-speaking fans.
