You know that this is a peice of fiction right? It does not have to be accurate or match Japanese culture. This manga is the writer's fantasy, his interpretation of a zombie apocalypse he can do whatever he wants with it.
Sorry, I didn't answer your actual question.
Yes it is a type of comedy, but it is more common in manga, animes and cartoons,not much of a live performance thing, Kenchirou's act is extremely exaggerated.
Again I'm sorry, for not understanding ur real question ╥...╥
Why is Kenichirou always naked? Is this funny in Japan? I genuinely want to know, it was funny in the beginning but I don’t understand if it is funny/ comedy in Japanese culture
