The Gosho Aoyama Manga Factory is a small museum in Hokuei, the hometown of Gosho Aoyama, creator of Detective Conan. Inside, you’ll find original drawings, explanations about the manga creation process, character displays, and exclusive exhibits about the author’s work. I found it easy to visit and well paced, even if you’re not a hardcore fan. It’s clear, playful, and gives good context about how Conan was created and why the series became so popular.
