I had said it and i will say it again : you canNOT beat a Japanese singing a Japanese song. The sound coming from her vocal chords is so... Japanese. The perfect milisecond of the note timings and how she gets airbreath are very much like the original. The lyric "chikyuu no yoake wa" in 0:54 is totally only can be singing with Japanese mothertongues. My tongue can't replicate it, we have different "UU" sound.
