i notice hitomi and nako re impressive level in korean when they speaker korean even get deep voice .
Nako look best speaker but hitomi is better in writeen even she write both bsides japanese and korean
Sakura know basic korean like french speaker english... i guess her strong accent in korean songs .
I think this age nako and hitomi has debuted at 17 years old with izone and sakura is debuted at 20 years .
Difficult of language is hard for oldest people if you didnt facilities.
I know momo isn't great in korea so i remember she has forget her japanese .
Sana look best speaker in korea but mina is little nervous
I wonder their level
