Great Detective Conan, officially translated as Detective Conan) in Japan, is a Japanese detective manga series written and illustrated by Gosho Aoyama. The series is serialized in Shogakukan's Weekly Shōnen Sunday since January 19, 1994, and has been collected in 81 tankōbon volumes as of June 2013.
