I would recommend Acid Black Cherry. It's a solo project from Janne Da Arc's vocalist yasu. I really love his music and he is a really great musician! He also sings really good, that's for sure, but if you will like his voice or not depends, 'cos he hasn't a typical (japanese) singing voice.
Maybe you already listened to him, 'cos his "2012" album was the one that got the number one spot instead of Party Queen. But I would also give his albums BLACK LIST and Q.E.D. a try, 'cos they are somewhat different than "2012".
I also really like him because he has a great sense of humor! Here are two PVs, the first one is the first song he released as Acid Black Cherry and the second one is his new single which will be out in August.

If you would like to try his albums, I would be glad to upload them for you.
