Can anybody recommend any Japanese artists to me?

[ILoveGeniuses]

I've been looking to branch out even further from my current Japanese music. I've already been exploring KPOP, American & British music as well, but I'm having trouble finding some more Japanese artists I like. So here's two lists. One of the artists I already like/love & listen to, and the 2nd of ones I've tried, but didn't care for. Can anybody think of any others for me to give a try?
