Haikei kono tegami yondeiru anata wa

Keep on believing, keep on believing, keep on believing

Dear you,
Who's reading this letter
Where are you and what are you doing now?

For me who's 15 years old
There are seeds of worries I can't tell anyone

If it's a letter addressed to my future self,
Surely I can confide truly to myself

Now, it seems that I'm about to be defeated and cry
For someone who's seemingly about to disappear
Whose words should I believe in?
This one-and-only heart has been broken so many times
In the midst of this pain, I live the present

Dear you,
Thank you
I have something to tell the 15-year-old you

If you continue asking what and where you should be going
You'll be able to see the answer

The rough seas of youth may be tough
But row your boat of dreams on
Towards the shores of tomorrow

Now, please don't be defeated and please don't shed a tear
During these times when you're seemingly about to disappear
Just believe in your own voice
For me as an adult, there are sleepless nights when I'm hurt
But I'm living the bittersweet present

There's meaning to everything in life
So build your dreams without fear
Keep on believing

Seems like I'm about to be defeated and cry
For someone who's seemingly about to disappear
Whose words should I believe in?

Please don't be defeated and please don't shed a tear
During these times when you're seemingly about to disappear
Just believe in your own voice

No matter era we're in
There's no running away from sorrow
So show your smile, and go on living the present
Go on living the present

Dear you,
Who's reading this letter
I wish you happiness
