Lyrics & Translation

Dive into the world of J-pop with Hinatazaka46's 'Enshū-ritsu'. This song is a fantastic way to learn Japanese vocabulary related to mathematics and emotions, while exploring how metaphors are used in modern Japanese songwriting to describe the complexities of the heart.

[English]
The sunlight streaming through the window
Reflects off the blackboard, making it hard to see
The important things aren't written there anyway
I spend all my time just gazing at you
I wonder what all these
Rows of numbers actually mean
Just like the digits of Pi never end
Truthfully, I wanted to keep going too
An eternal decimal point
The words of love I want to tell you
No matter how far, no matter how long, even through billions of digits
My feelings for you can never be divided
Is you sitting diagonally in front of me
A stroke of luck, or just my misfortune?
The more I lose focus on the lesson
The happier I seem to feel
Love is infinite
It's just a feeling of "liking" that keeps on going
22 divided by 7, the numerator over the denominator
I find myself thinking of it over and over
I can't seem to organize this affection
With the haze in my heart never clearing
This endless emotion is, for me right now,
Yes, more precious than anything else
どこまで行けば 答えが出る?
Though nobody really knows
My round, full heart
Thinks of you without ever stopping
Just like the digits of Pi never end
Truthfully, I wanted to keep going too
An eternal decimal point
The words of love I want to tell you
No matter how far, no matter how long, even through billions of digits
My feelings for you can never be divided
Something like Pi will never be enough to express it
