The story takes place in the mighty Northern field of Hokkaido, the time is in the turbulent late Meiji Era. A post war soldier Sugimoto, aka, “Immortal Sugimoto” was in need of large sums of money for a particular purpose…. What awaited Sugimoto, who stepped into Hokkaido’s Gold Rush with dreams of making a fortune, was a tattoo map leading to a hidden treasure based on hints inscribed on the bodies of convicts in Abashiri Prison?! The magnificent nature of Hokkaido vs vicious convicts and the meeting with a pure Ainu girl, Ashiripa!! A survival battle for a hidden treasure hunt begins! 

Golden Kamuy is based on Satoru Noda's historical adventure manga, which is available from Shueisha. The first, second, and third seasons made their debuts in 2018, 2020, and 2021, respectively.

Shizutaka Sugahara, the director of Rin-ne, D-Frag!, and Grimms Notes: The Animation, is the new chief director of Golden Kamuy Season 4, which is produced by Brain's Base rather than Genos Studio like the previous seasons. Takumi Yamakawa, the character designer for To Your Eternity, In/Spectre, and Grimms Notes: The Animation, is a new member of the staff.

The Shueisha-published Golden Kamuy manga ran from 2014 to 2022, ending with 31 tankoubon volumes. It was serialized in Weekly Young Jump and is published under the Young Jump Comics label. Viz publishes the manga in English.
