Αυθεντικό κείμενο - Ιαπωνέζικα - Koko ni aru no wa kimi ga ima made ...

Hi Ian, again...is this transliteration acceptable and understandable?

CC: IanMegill2

it's the translation which i've found on sites of lyrics

Koko ni aru no wa
kimi ga ima made eranda michi no
kotae tachi yo
Hora, jishin motte susumeba ii
totemo shizen na no
ame agari no
asufaruto ni niji kakaru you ni
lonely kaze ga fuite

What is here (what remains) are the answers to (results of)
the choices you have made until now (lit: the "roads you have chosen until now" )
Listen, you should have confidence and go ahead (continue living your life your way)
It's completely natural
The way a rainbow appears over the asphalt (i.e. the road) when the rain stops
A lonely wind blows
