it seems Japanese. meaning is "so much innocent". btw, "JAP" is a word using to insult Japanese. if you write abbreviation of "Japan", i recommend you to use "JPN".

i think it is japanese too. it goes "Hikaru ni mujyakina.." it should added to the end "hito": person, or "koekei": scean. not cpmpleted sentence. and like yellowseadog said JAP is insult, ( i understnad asker only made it short ) and i don`t understand KOR... probably Korean refer to the Japanese.
