Hayaoki no nichiyoubi wa doushite
Konna ni takanaru no?
Mizutamari tobikoete utaeba
Yomigaeru yo mujaki na kimochi

Naritai mono ni yatto deaeta
Ano koro no (ano hi kirara) tokimeki wa ima demo!
(xǐ yuè, wú jiān, yuán yuán bù jué, xī wàng jiù zài yǎn qián)

Mizuiro no Sunday Sunday
Itsumademo nande nande
Bokura wa yume bakari mite irun darou ne
Suteki da ne Sunday Sunday
Nani mo kienai ne nai ne
Houseki sore yori kirei sa
Akogare wa

Mada nemuru oodoori nonbiri
Noraneko ga aruiteru
Ato sukoshi jikan ga tateba kitto
Kazoekirenai hito de nigiwau

Keshiki mo kaze mo ironna kao de
Sugiteku yo (sugiru fuwawa) boku datte iroiro!
(měi tiān, měi yuè, bù tíng zhuǎn biàn, jìn shì xīn de fā xiàn)

Sore nano ni Sunday Sunday
Negai dake nande nande
Itsumo onnaji kao de waratterun darou ne
Daisuki sa Sunday Sunday
Tachidomarenai ne nai ne
Arukou asahi ga sasu michi
Dokomademo!

Sukippu sukoshi iki made hazunde
Kokoro ga hora ne karoyaka ni odoru yo
(xǐ yuè, wú jiàn, yuán yuán bù jué)

Mizuiro no Sunday Sunday
Itsumademo nande nande
Bokura wa yume bakari mite irun darou ne
Suteki da ne Sunday Sunday
Nanimo kienai ne nai ne
Houseki sore yori kirei sa
(Mabushii kurai ni)
Kono mune de hikaru
Akogare wa

早起きの日曜日はどうして
こんなに高鳴るの？
水たまり飛び越えて歌えば
よみがえるよ無邪気なキモチ

なりたいものにやっと出会えた
あの頃の (あの日きらら) ときめきは今でも！
(喜悦、無間、源源不絶、希望就在眼前)

水色のSunday　Sunday
いつまでもなんで　なんで
僕らは夢ばかり見ているんだろうね
素敵だねSunday　Sunday
何も消えないね　ないね
宝石それより綺麗さ
あこがれは

まだ眠る大通りのんびり
ノラ猫が歩いてる
あと少し時間が経てばきっと
数えきれない人で賑わう

景色も風もいろんな顔で
過ぎてくよ (過ぎるふわわ) 僕だってイロイロ！
(毎天、毎月、不停轉變、盡是新的發現)

それなのにSunday　Sunday
願いだけなんで　なんで
いつもおんなじ顔で笑ってるんだろうね
大好きさSunday　Sunday
たちどまれないね　ないね
歩こう　朝陽がさす道
どこまでも！

スキップ　すこし息まではずんで
心がほらね　軽やかに踊るよ
(喜悦、無間、源源不絶)

水色のSunday　Sunday
いつまでもなんで　なんで
僕らは夢ばかり見ているんだろうね
素敵だねSunday　Sunday
何も消えないね　ないね
宝石それより綺麗さ
(眩しいくらいに)
この胸でひかる
あこがれは

Why am I so excited
On this early Sunday morning?
Singing while jumping over puddles on the street,
Brings back feelings of innocence and childhood.

I've finally found what I want to become,
The thrill from that time (the shine from that day) is still here, even now!
(Joy stretches out endlessly, hope is before my eyes!)

It's a sky-blue Sunday, Sunday.
Why, why is it that we're always
Dreaming about our dreams and nothing else?
It's a wonderful Sunday, Sunday.
Nothing will disappear, nothing at all.
This admiration's more beautiful
Than a precious gem.

The streets are still asleep, peaceful,
A stray cat strolls down the street.
In just a bit, it's gonna be
Full of people, bustling about.

There's all types of scenery
And ways the wind blows by (blowing by, fluffily); and there's a bunch of sides to us as well!
(Every day, every month, everything's constantly changing, and we keep discovering new things!)

But even so it's Sunday, Sunday.
Why, why are you just wishing?
We're always laughing this way, aren't we?
I love this Sunday, Sunday.
Don't just stay still, don't!
Let's walk on this sun-bathed street,
As far as we can go!

Skip about until you start breathing a bit hard,
Look, your heart, it's dancing about gracefully!
(Joy stretches out endlessly.)

It's a sky-blue Sunday, Sunday.
Why, why is it that we're always
Dreaming about our dreams and nothing else?
It's a wonderful Sunday, Sunday.
Nothing will disappear, nothing at all.
This admiration,
Lighting up our hearts,
(It's almost blinding)
Is more beautiful than a precious gem!
