What Is Detective Conan?

Created by Gosho Aoyama, Detective Conan first appeared as a manga in 1994 before becoming one of the longest-running anime series in history. The story follows Shinichi Kudo, a brilliant high school detective famous for solving complex criminal cases.

Everything changes when Shinichi witnesses a suspicious deal involving the mysterious Black Organization. After being attacked and forced to take an experimental poison, his body unexpectedly shrinks into that of a young child. To protect his identity, he takes on the name Conan Edogawa while secretly continuing to solve crimes and search for a cure.

Throughout the series, Conan works alongside his childhood friend Ran Mouri and her detective father, Kogoro Mouri, solving countless mysteries while keeping his true identity hidden.

Fans love Detective Conan because it combines suspense, humor, emotional storytelling, and clever detective work. With over a thousand anime episodes and numerous feature films, it continues to attract both longtime fans and new audiences around the world.
