The Japanese cartoons with a fantasy theme are commonly known as "anime." This term refers to any style of animation produced in Japan, but in the west, it has come to specifically refer to Japanese animated shows and movies. Anime has gained a significant following worldwide, known for their unique and often visually stunning art style, complex storylines, and diverse character designs. Many anime series are based on popular manga (Japanese comic books) and have become cult classics, with franchises spanning decades. Popular anime series include Naruto, One Piece, Attack on Titan, and My Hero Academia.
