I reccomend the band Supercell.They are the one that made a lot of beliebt vocaloid songs like melt,World is Mine,Love is War,and Black Rock Shooter.They also made songs for vocalists that are real.This is my Favorit song from them

Koda Kumi.
She is AMAZING! listen to her songs Pop Diva, Taboo, Lollipop and At The Weekend, they're all SO catchy!
I also like Namie Amuro
The songs I like of hers the best are Full Moon and Hide and Seek
Listen to all those songs, they're seriously amazing
But they're the only j-pop artists I listen to, cause they're modern sounding
