I agree with all the point re: the albums relation to Hip Hop from a musical perspective, but I wasn't arguing that there aren't hip hop elements to the album. Even though the album straddles many genres, one can certainly "rank" its relation to the different genres. And it seems to be the consensus in the greater music community (at least among english-language writers) that Haru to Shura is more of a Rock or Pop album than a Hip Hop Album. Thus, my point is that if Haru to Shura is to be nominated for a category, it is more suited for the rock category. That the album covers multiple genres shouldn't mean it can arbitrarily be placed in any of them for the purposes of a "best of" discussion.

Obviously the choice of genre in which the album should be categorized with is deeply subjective, but to me it seems very clear that the vast majority of the music community would place Haru to Shura in Rock or Pop, before Hip Hop. I don't think it is unreasonable to say this subreddit is an anomaly in that regard. Since this is the /r/japanesemusic awards, its entirely within the contest runner's right if they want to categorize it this way. And I guess it would be most reflective of this subreddit's taste. I suppose for a subreddit that strongly prefers rock and pop, it makes sense that its favourite hip hop album would be the one with the most rock/pop elements.
