When the bell went for the end of classes
We suddenly blindfolded you
Without giving you time to object, we took your arm
And took you away to the gym

We made you stand, nervously
By the basketball hoop
You asked “What are you doing?”
But we didn’t answer, keeping you in suspense

All our classmates got together
And planned this in secret (in secret)
You can take the blindfold off now
That’s the sign, all together
Everyone lets off party poppers
3! 2! 1! O!

Happy! Happy [bad word] on, blow out
All the candles on your cake
In one go
Let’s start this party for you
Happy! Happy birthday
Our plan was a big success
We remembered
Your birthday
big crowd of your friends
Are singing to you
And surprise tears
Appear on your cheeks

Let’s make a toast
With our paper cups
Here’s something from all of us
present with messages from everyone

You’re only seventeen once
The photo we all took together
Surrounded by the chirping of cicadas in the summer
Is our time capsule

We’re living (living) in the same times
In a corner of the world
This could surely be youth
We’re sure to think back on this
Someday, years from now
3! 2! 1! O!

Happy! Happy birthday
Wishing you a wonderful year!
You’re one year closer
To adulthood now
Yes, spend the next year well, in your way!
Happy! Happy birthday
You’re not alone
When you face
Hard times
See, look around
We’ll be by your side
Surprise tears
With our smiles

Happy! Happy [bad word] on, blow out
All the candles on your cake
In one go
Ah, may it bring you happiness in the future...
Happy! Happy birthday
There are still plenty more dreams [bad word] Before your eyes
The road to the future
Is shining
Start by taking
One step
