English Translation:

The twinkle,twinkle
The twinkle, twinkle

Even when hidden, I twinkle, what can be done?
I stand out completely
Even when shrouded in a veil
I twinkle, it’s obvious

All the other people also
like me because I shine
I have to always be on watch
You’re the one who stole the jewel

Keep watch of my surroundings for me all the time
Circle around only me
Please don’t take your eyes off me
Fall into my charms

Even when hidden, I twinkle, what can be done?
I stand outcompletely
Even when shrouded in a veil,
I twinkle, it’s obvious

I’m an unknown world
You’ll probably lose track of time
Even when you open your eyes in the morning
Your dream will still continue

I get dolled up for you
I want to shine even more beautifully
Why are you the only one not to know
My true value?

Even when hidden, I twinkle, what can be done? (Even when hidden, I twinkle, I shine)
I stand outcompletely
Even when shrouded in a veil
I twinkle, it’s obvious

You’re too nonchalant*, you’re so shameless
There’s a never-ending line of people outside who wish** for me
You’re too calm, it doesn’t make sense
I’m a star that fell from the sky

Even when hidden, I twinkle, what can be done?
I stand outcompletely
Even when shrouded in a veil
I twinkle, it’s obvious

Look at me, your twinkle
Where are you looking? Look at me
Even under dull clothes
My twinkle takes its form

Even when hidden, I twinkle, what can be done? (I twinkle, what can be done?)
I stand outcompletely
Even when shrouded in a veil
I twinkle, it’s obvious
You know I twinkle
