I don't know exactly where to write this and at first I thought about not sharing it since it's nothing THAT important but I suppose that it's also a way to show how good KARA is doing in Japan. And yeah, everyone and their moms know by now how popular they're in Japan and how many idols/singers loves them but I don't think there has been talk about Japanese rock bands (be it rock bands, visual kei or another kind of variation from rock) being fan of them.
There was once, just when KARA debuted in Japan than a member of a visual band which I don't even know talked about them and you could see his fans asking about KARA though I can't show any proof.
The other day, the band Duel Jewel had a twitter event with Cure (Japanese magazine about visual bands) where people ask them questions and in two questions one of the boys, Yuya, showed how much of a fanboy he was.
One question was about your favorite animal and since boys of this kind of bands tend to change topics and just tell whatever they feel like saying, Yuya answered saying just KARA (original tweet) and then, choosing which celebrity they would like to be for one day he went again with KARA (original tweet).
Not with that, today there was a tweet from Yukke (of MUCC which is a really famous band) saying that he was studying Kpop (original tweet). This may not mean nothing but the only two persons he is following from the Kpop fandom is Hara and Nicole so he may have wanted to learn about Kpop after listening/watching KARA xD
Again it's nothing too important and people from jrock tends to love idols but thanks to them their fans who usually aren't into pop or just lives from rock are knowing about the girls.
BTW I see so much KARA in the weekly chart! :DDDDDDD
