Japanese (Kanji / Kana)
ねえ 夏の強い陽射しに
街が乱反射しているよ
もう 君が影に隠れてても
誰かにすぐ見つかるだろう
一人きり 閉じ籠ってた
心から飛び出してみよう
太陽ノック
誘っているよ
空の下は自由だと言ってる
何か始める
いいきっかけだ
熱くなれる季節に
Open the door!
ああ 光り輝いてても
やがて 夏は過ぎ去って行く
そう 君はその時の寂しさ
感じ取って臆病になる
未来とは 今が入り口
見逃せば前に進めない
太陽は味方
いつも変わらず
すべての人 照らしてくれるんだ
不安な雲も
切ない雨も
また昇って微笑む
Grab a chance!
流れ出す汗の分だけ
その夢がかたちになるんだ
太陽ノック
誘っているよ
空の下は自由だと言ってる
情熱ノック
外に出ようよ
眩しいのは晴れ渡る未来だ
何か始める
いいきっかけだ
熱くなれる季節に
Open the door!
秋風が吹いても
Grab a chance!
Translation
Hey, summer’s strong sunshine
Is diffusely reflected throughout the city
No matter how you try to hide in shadow
Someone will soon find you
You’ve been alone, shutting your heart away
Try jumping out now
The Sun’s knocking
Inviting you out
Saying that you’ll be free under the sky
It’s a great chance
For something to happen
In this heating season
Open the door!
Ahh, no matter how much it shines
Summer is eventually pass
Yes, you are afraid because you sense
The loneliness which will come then
The present is the entrance to the future
If you miss it, you can’t progress
The Sun is your ally
Always unchanging
Shining down on everyone
Despite the anxious clouds
Despite the sorrowful rain
It’ll rise again and smile
Grab a chance!
Your perspiration
Helps to form your dreams
The Sun’s knocking
Inviting you out
Saying that you’ll be free under the sky
Passion is knocking
Asking you to go outside
The future is clear and dazzling
It’s a great chance
For something to happen
In this heating season
Open the door!
Even when the autumn wind blows
Grab a chance!
