Quick and dirty, here's the Japanese.
In a Strange World - Ranmadou
In a strange world
In a strange car
I had a strange dream
You said to me
"Let's go on a trip together!"
When I'm with you I
feel so good
In a strange world
In a strange car
I had a strange dream
You said to me
"Let's take a trip together!"
When I'm with you I
Would it be cool if yellow me were dyed black? [1]
Or white?
Cigarette smoke tickles my throat
What should I smear across the blue sky?
Ashes, this time?
Cigarette smoke tickles my throat
What should we hide? What's on the other side?
What around me is colorful? Ahh, I don't know.
I don't get it.
Curses and laughter make brilliant shadows
A silently sinking excitement [2]
falls on the highway
They say we were born
on a meaningless Saturday
When you're in a melancholy this deep
The words and the sky definitely don't have the answers [3]
A puzzle I can't solve
is wrapped in an overcoat
Summer comes to us, backlight
when we thread our way through the buildings
It's summer. Now, smile
They say it's summer!
In a strange world
In a strange language
I heard a strange story
You said to me
"Let's take a trip together!"
When I'm with you I'm
not scared of anything
In a strange world
In a strange language
We're having a strange conversation
