**Anime** is a term primarily used to refer to **Japanese animation** (from the English word "animation," shortened to "anime" in Japanese pronunciation). ### Key Characteristics: - **Art Style**: Distinctive visuals with exaggerated expressions, large eyes, dynamic action sequences, and vibrant colors. Backgrounds are often highly detailed. - **Genres**: Covers everything from shōnen (action/adventure for young males, e.g., *Naruto*, *One Piece*), shōjo (romance/drama for young females, e.g., *Sailor Moon*), seinen (mature themes, e.g., *Attack on Titan*), to slice-of-life, horror, mecha (giant robots), and isekai (transported to another world). - **Formats**: TV series (often 12–24 episodes per season), movies, OVAs (original video animations), and ONAs (online exclusives). Episodes are typically 20–25 minutes. ### History & Origins: - Roots in early 20th-century Japanese animation, influenced by Western cartoons. - Pioneered post-WWII by studios like Toei Animation (*Astro Boy* in 1963 was the first major TV anime). - Exploded globally in the 1980s–90s via exports like *Akira* (1988) and *Dragon Ball*. - Today, a massive industry worth billions, with streaming platforms like Crunchyroll, Netflix, and Funimation making it accessible worldwide. Anime is often adapted from **manga** (Japanese comics), light novels, or created as originals. It's not just "cartoons"—while aimed at all ages, it frequently tackles complex themes like existentialism, trauma, or politics. If you're new, start with classics like *Fullmetal Alchemist: Brotherhood* or *Spirited Away* (Studio Ghibli film). What's your favorite or what got you interested?
