KAT-TUN - Come Here

I'm kind of on a mission. Not that there isn't enough awesome K-Pop to keep me going forever, but I'm also trying to dip a toe into the gigantic and sometimes very weird pool that is J-Pop. I don't think I'll ever be a massive fan for a number of reasons, including aural aesthetics that just don't completely align with my personal taste, but I want to get familiar. In my brief studies, I ran into a group called KAT-TUN that sounds a bit more on the K-Pop side. In particular, I've been giving a lot of love to their most recent full-length album. The title track reminded me of a Shinee single the first time I heard it. Then I went on wikipedia and, lo and behold, it's because it shares some writers that have worked on Shinee material in the past. Even so, Come Here is a dynamite slice of hyper active power pop. More than anything, it's a great bridge that will hopefully give me some confidence to continue exploring. I'm wondering, are any of my readers J-Pop fans? If so, what would you recommend? I'm dreaming of finding something that sounds like Infinite, but I'm doubtful that it exists.
