Romaji

Yozora wo miage hitori houkiboshi wo mita no
Isshun de hajikete wa kiete shimatta kedo
Anata no koto omou to mune ga itaku naru no
Ima sugu aitai yo dakedo sora wa tobenai kara

Moshi atashi ga houkiboshi ni nareta naraba
Sora kakenuke tonde iku
Donna ashita ga kitemo kono omoi wa tsuyoi
Dakara houkiboshi zutto kowarenai yo

Ame ga futte iya da to boyaite ita toki ni
Anata ga itta koto ima demo oboeteru
Ame no ato no yozora wa kirei ni hoshi ga deru
Sore wo kangaeru to ame mo suki ni nareru yo ne to

Moshi atashi ga houkiboshi ni nareta naraba
Afureru hikari furasu yo
Itsumo kanashii toki yozora miru anata ga
Egao ni naru anda ni moto kagayakitai

Anata wa itsumo hitori nanika to tatakatteru
Soba ni iru koto shika atashi niwa dekinai kedo

Moshi atashi ga houkiboshi ni nareta naraba
Sora kakenuke tonde iku kitto
Kanarazu todoku kono isshun no hikari de
Anata no ima terashi sora wo megurou
Atashi ga houkiboshi ni nareta naraba
Kitto soba ni ite ageru donna toki mo

Kanji

夜空を見上げ一人　ほうき星を見たの
一瞬ではじけては　消えてしまったけど
あなたのこと想うと　胸が痛くなるの
今すぐ会いたいよ
だけど空は飛べないから

もしあたしが　ほうき星になれたならば
空駆け抜け　飛んでいく
どんな明日が来ても　この想いは強い
だからほうき星ずっと　壊れないよ

雨が降って嫌だと　ぼやいていた時に
あなたが言ったこと　今でも覚えてる
雨の後の夜空は　綺麗に星が出る
それを考えると
雨も好きになれるよねと

もしあたしが　ほうき星になれたならば
溢れる光　降らすよ
いつも悲しい時　夜空見るあなたが
笑顔になるように　もっと輝きたい

あなたはいつも一人　何かと戦ってる
傍にいることしか
あたしにはできないけど

もしあたしが　ほうき星になれたならば
空駆け抜け　飛んでいく　きっと
必ず届く　この一瞬の光で
あなたのイマ照らし　空を巡ろう
あたしが　ほうき星になれたならば
きっと傍にいてあげる　どんな時も

English Translation

Looking up to the night sky alone, I saw a comet
In an instant it burst open, and disappeared
When I think of you, my hati, tengah-tengah aches
I want to see anda right now
But I can't fly

If I could turn into a comet
I would run through the sky and fly
No matter what tomorrow is like, these feelings are strong
So this comet will never break open

When I grumble about hating it when it rains
I even now remember what anda would say
Stars will come out beautifully in the night sky, after the rain
When I think about that
I think that I can grow to Cinta the rain too

If I could turn into a comet
I would shed my overflowing light
Whenever I was sad, anda would always look up to the night sky
And make it shine even more, so that I would smile

You're always alone, and fighting with something
But I can't be
At your side

If I could turn into a comet
I would run through the sky and fly
It will definitely reach you, in the light of this moment
Your moment shines, bringing the sky around
If I could turn into a comet
I would certainly be sejak your side, at any time
