@beatchef: I have in fact heard of KOTO! Actually, the video you posted was something that's been on my list of things to post since I discovered it a few months ago. I love her energy, particularly in the way she dances.
Not sure how into modern JPOP Jeff really is; I know he stumbled into Charisma.com through the same @aurahack post that I did a few years ago, but I'm not sure how far down the rabbit hole he went with that. Outside of Charisma.com and Tommy February, I have no clue what JPOP he might like. Suiyoubi no Campanella might be right up his alley though. Speaking of...
A new Suiyoubi release! This one is probably my favorite of the year so far. It has a sound that is never not perfectly on point, catchy and dripping with style. KOM_I's sharp vocals echo perfectly throughout the entire song. The video is typical Suiyoubi flair, beautifully shot and filled with amusing moments of KOM_I dancing her way through areas she shouldn't be. It all comes together in a way that's infinitely more catchy and mainstream than her previous releases, which is likely why I enjoy it so much more.
Here's a new Daoko track, albeit one a bit different from the norm. Anyone who's heard her previous releases will likely notice that this track is far more pop than hip hop, with upbeat instrumentation and a more typical song structure. While this song does feel less unique than Daoko's prior tracks, I still think it's amazingly well done. It sounds like a song you'd likely find in a Dance Dance or Pop'n Music game at one moment and then transitions into a filthy synth line the next. I do think the vocals are a bit weaker overall, but the strength of the composition more than makes up for it.
Oh Boy! - AOA (non-Youtube link)
AOA was originally a Korean pop group, but they have begun to heavily transition into the Japanese market in the last year. While their previous releases were fine, Oh Boy! is their first legit Japanese banger. If you're familiar with both Japanese and Korean music, you'll immediately be able to tell that this song sounds more like a Korean-style pop song, just with Japanese lyrics. As such, you'll find pounding club beats and a powerful chorus that feels nearly impossible to hate. Throw in a slick rap verse and it wouldn't be ridiculous to think that some might mistake this for a Korean track. Nonetheless, it is a Japanese track--and quite a fantastic one as well.
