User blog comment:Shimazu Sumiko/Can't Find Kanji for a Song, Need Help/@comment-26239285-20160220003225

Japanese transcribed from the video:

会いたいよ 君に会いたいよ

あぁ、居たいよ 君と居たいよ

あぁ、痛いよ 胸が痛いよ

Romaji:

Aitai yo Kimi ni aitai yo

Aa, itai yo Kimi to itai yo

Aa, itai yo Mune ga itai yo

My translation (or you go can go with the one you mentioned if it sounds equivalent):

I want to see you, I want to see you

Ah, I want to be with you, I want to be with you

Ah, it hurts, my chest hurts
