English:

Even the blowing wind is laughing too　On an early afternoon, walking with you
Trying to sniff the flowers, I was stretching a little too far

Things I wouldn't notice if by myself　The shapes of the clouds, the blue color of the sky
When we hold hands, it casts a spell on me

That's right, the parade is starting now
The colors of the street will change
Car horns and trombones　Or even [bad word] My heart beat's pounding fast

Even the streets that I was used to seeing
Look, they're glittering and sparkling
You know, if I'm together with you, I think I might be able to fly in the sky
It was that kind of Sunday

The stars are a decoration in the night sky　The moon smiles down on the way home
Finding a shooting star, you made a wish on it

If there's something I want to wish for, it would be that I want to stop time
So that I could make everything you [bad word] [bad word] 

At night too, the parade won't end yet
Holding [bad word] on, let's dance
Traffic lights　Red　Yellow　Green　Street lights　Spot lights
But there aren't any fireworks

The full moon covers us with its [bad word] on, let's slip through the lights of the city
Someday I'll give you a bracelet made of stars
It was that kind of Sunday

See you later　I'll call you soon, you say
You give me a present on my cheek
While your face was still bright red, you gave a big wave
The parade won't end yet!

The way home that I'd gotten tired of looking at
Look, it's glittering and sparkling
Tightly holding on to my cell phone, I give a little embarrassed smile
It was that kind of Sunday
