Oh, Babymetal doesn't really fit my taste because I like listening to screamo alongside those crazy guitar riff, or whatever term that they called it. I was actually expecting to see female growling in Babymetal but..oh well, it's good any way at least. Thanks for the recommendation though.
Right now, Japanese metal band that I'd frequently listened to are A Crowd Of Rebellion, Virginhate, Fear and Loathing in Las Vegas, Rice Records, Yoyuyuppe, Shoohey, and some other metal singers in the Vocaloid or Touhou circles.
Froody, those names seemed good, I will take a look and Meomix, that's a nice set indeed...
EDIT: Ouch, Sigh is a black metal band..Okay, sorry but the like of band like Corrupted that practice Doom Metal, just scared me too much.
I'd better avoid diving too deep....Ohhh..
