Man, I've been so out of Jrock, so I have no idea about these newer bands
. I'll check out some of Sakura_Genki's list.
My favourites include, MUCC, Dir en grey, Plastic Tree, Kagrra, Girugamesh, Merry, Zi:Kill, Kalimero, La Vie En Rose, Love Psychedelico, D'espairsRay, Coaltar of the Deepers, Aikawa Nanase.
