The short and sweet version is rock bands that put a little more into how they look.

When it first started off, you had bands like X Japan that had really elaborate costumes, but recently, it's gone towards looking more like street fashions and the make up has become a little less extreme.

And then you've got different kinds, like oshare kei and kote kei.
And a couple more, but those are two I can name off the top of my head.
