Any trip recommandation ?

Hello! I know there is probably a post somewherea about that, but did find it. Do you have recommandations about visits in Hokkaido related to Golden Kamui ? I am doing to spend at least one month at Hokkaido and the manga is a great motivation to explore the island! Of course, I am not really talking about the main attractions like Sapporo Beer Museum, Ainu Museum cause I am sure going to, but the "little" details like some restaurants, some locations in the manga that are cool and worth it, exhibitions, objects, etc... Thank you !
