This is Utada Hikaru's Final Distance. It is in Japanese so obviously I don't understand it. So I got the english trans below. :D The Jap song copy is what I have so I sing with it sometimes. . Thanks tif for the song copy! :D

Romaji:

Ki ni naru noni kikenai
Oyogitsukarete kimi made mukuchi ni naru

Aitai noni mienai nami ni osarete
Mata sukoshi tooku naru

Togirenai you ni keep it going baby
Onaji kimochi janai nara tell me
Muri wa shinai shugi demo
Sukoshi nara shite mite mo ii yo

I wanna be with you now
Futari de distance chijimete
Ima nara maniau kara
We can start over
Hitotsu ni wa narenai

I wanna be with you now
Itsu no hi ka distance mo
Dakishimerareru you ni nareru yo
We can start sooner
Yappari I wanna be with you

Hito koto de konna ni mo kizutsuku kimi wa
Kodoku wo oshiete kureru

Mamorenai toki keep on trying, baby
Yakusoku doori janai kedo trust me
Muri wa shinai shugi demo
Kimi to nara shite mite mo ii yo

I wanna be with you now
Futari de distance mitsumete
Ima nara maniau kara
We can start over
Kotoba de tsutaetai

I wanna be with you now
Sono uchi ni distance mou
Dakishimerareru you ni nareru yo
We should stay together
Yappari I need to be with you

English:

I'm anxious but I can't say anything
I'm tired of swimming, even you've become silent

I want to see you, but an invisible wave pushes us
Again, just a little more distance

Try not to stop keep it going baby
If you don't feel the same then tell me
Even if your principle is to not try
It's alright to try a little

I wanna be with you now
Let's shorten the distance with the two of us
We can still make it on time
We can start over
We can't be as one

I wanna be with you
Someday even this distance
We'll be able to embrace
We can start sooner
After all I wanna be with you

You, who gets hurt with a single word
taught me what loneliness is

When you can't protect me keep on trying baby
It's not as I promised but trust me
My principle is to not try but
I would do it for you

I wanna be with you now
Look at our distance with the two of us
We can still make it
We can start over
I want to tell you with words

I wanna be with you now
One day, even the distance
I'll be able to embrace
We should stay together
After all, I need to be with you
