Takao Saito’s Golgo 13 manga broke the Guinness World Record for “most volumes published for a single manga series” when its 200th compiled book volume shipped in Japan on April 5, 2021. The manga is currently tied with Osamu Akimoto’s Kochira Katsushika-ku Kamearikouen-mae Hashutsujo (“Kochikame”) manga, which earned the record when its 200th and final compiled book volume shipped in September 2016.
The manga, focusing on the titular legendary hitman, is the oldest manga still in publication. Saito launched the manga in Shogakukan’s Big Comic magazine in 1968. VIZ Media published 13 volumes of the manga in North America between 2006 and 2008.
