Otaku vs Weeb: What’s the Difference?

The words otaku and weeb are often used to describe anime fans, but they do not mean the same thing.

This guide explains how the terms differ, where they come from, and how to use them correctly.

What Is an Otaku?

An otaku is a Japanese term that describes someone who is deeply passionate about a hobby, most commonly anime, manga, or video games.

In Japan, the word can sometimes carry a negative meaning, suggesting social isolation or obsession. Outside Japan, however, many fans use the word proudly to describe themselves.

What Is a Weeb?

A weeb is a non‑Japanese person who is extremely interested in Japanese culture, especially anime and manga.

Unlike “otaku,” the word comes from internet slang and is mostly used online.
