Yeah, I think so. Although there are some other reasons that the full series wasn’t done, I think. The whaling volume stands out as one that would not have gone over. There are some others like the chapter where they talk about eating horse, etc. That most western audiences would not find acceptable.
Oh yeah, the Whaling and the Horse Meat Match chapters, they definitely won't survive if they're translated into English since they'll just get slaughtered lol.
Still, those chapters (including some very late ones about eating dog meat), at least IMO, actually show how unexpectedly accepting the manga is for more niche and unusual traditional dishes that most modern people (Japanese and anyone else) would probably never want to eat because they think they're disgusting or don't align with their morals.
Even so, I understand if people don't want to eat them, especially if the sources are like shark fins and whale meat, since catching their sources will only harm the overall global marine environment.
