spyair 

B'Z

Sorimachi takashi

Fukuyama masaharu

For rock: One Ok Rock, Miyavi, The Gazette, Nightmare, An Cafe

Also not rock but Utada Hikaru is a must

If you want to try some J-rock-pop try Indigo La End. I love them. 

If you want to follow a band, then it's Hey! Say! Jump . My all time favourite :)

There are some more J-Pop MV songs on YT, but some of them are region blocked and restricted to Japan-only songs like Little Glee Monster.

Johnny & Assocaites also have YT, but i don't know if they upload MV on it.

Here are his account: https://www.youtube.com/channel/UC1cHlPIE-kqiPvpyYz2O8rQ/featured

As far as i can know more about J-Pop songs, there is an Exile (and other collective EXILE group) songs from Avex:

I know some Johnny's & Associates songs like Arashi, KAT-TUN, NEWS, Sexy Zone and others don't have YT, but if they're uploaded it here, they will be taken down by the copyright laws. And most of the J-Pop MV you find them on YT are almost short length, so you'll need to go an to an illegal video website to watch full MV.

I'm tempted to recommend 70/80s seminal electronic pop band Yellow Magic Orchestra (YMO) because of their influence on Japanese popular music in general. (And because I'm currently obsessed with them and would love to drag another person into YMO hell/heaven.)

Joking aside, since you're already familiar with Japanese bands from anime, what about picking several songs that you like and run them on Soundcloud or Spotify or even YouTube? Like it or not, their algorithm are pretty good, and you can get good recommendations based on stuff that you're already interested in.

But the video you get it from an illegal website and upload it on Youtube and Spotify will always be taken down by the copyright laws.
