Moshi ano hi no ame ga

Tonde itanara

Kitto sure tokutte itadakeka mo

Onaji hoshi wo onaji bashou de

Mitsumete ita you yo

Kimi no egaku mirai ni

Watashi wa iru no kana

Onaji sora wo onaji omoi de

Miagete ita yo

English
If the rain had stopped

That day

I might surely have just walked past you

If the bus had arrived

At its usual time

I wouldn't have met you

If that instant

Had been slightly different

We would have walked on separate paths of fate

I always want to watch

The same future together with you

Let's look at the same stars

At the same spot

I wonder if I am present

In the future you imagine for yourself

I want to look up to

The same sky with the same feelings

Our ways of talking and acting

Are really similar

It's like if we have always known each other

Mailing each other at the same time

Thinking about the same things

We might have been bound together by a red thread

We fit so well together, like if

It was decided by chance right from the start

I believe we are fated to be together

I wonder if I am present

In the future you imagine for yourself

I want to look up to

The same sky with the same feelings


 * repeat

So we may always walk

On the same path, hand in hand

Even on days filled with tears

And on sunny days
