English:

Ke　Ke　Ke　Ke sera sera

Over there, there's a spirit　It's a haunting in Shibuya
Anyone would [bad word] dazed and confused by the sweet words it tells you

Surrender yourself to the imitation world spun around by fake gods
With so much charisma that even crows dance
The password for one night, two nights
It's　Ke　Ke　Ke　"Ke sera sera"

Over there, there's a spirit　Giving an imitation of escaping　
If a gloomy rain is made to fall, no one will let go of those hands

Hey, you fake gods, please tell me　I want to understand so well that I know what you're thinking
Make-believe ghosts are luring you out
The password for one night, two nights　
It's　Ke　Ke　Ke　"Ke sera sera"

If you're half asleep or it's just an illusion, then you'll probably forget the pain
The waning and waxing moon shows the heat shimmering in the air
Even the melting lights of the city　Along with the mischievous noises around
You should take them all in
The awakening night will make your heart tremble and sing out　"Ke sera sera"

Surrender yourself to the imitation world spun around by fake gods
With so much charisma that even crows dance
The password for only one night, two nights...

Hey, you fake gods, please tell me　I want to understand so well that I know what you're thinking
Make-believe ghosts are luring you out
The password for one night, two nights　
It's　Ke　Ke　Ke　"Ke sera sera"
