Kanji

青い鳥 おとぎ話のように 幸せを 運んでくれる 信じてた
青い空 自由に飛ぶ姿に この想い 重ねては 願ってた

だけどいつかは 消えてしまう
幻のように 曖昧な 姿

忘れたことなんてないけど 滑り落ちるように
すり抜けて 泡のように 消える
それでも想いはずっとずっと 胸の深く深くで
眠るようにただ 息をひそめ 待ってる
解き放て カゴはもういらない

どこまでも 続く鏡の中に 幸せなあの日のわたし 映してた
遠い空 カタチのない世界に 本当の温もりを 探してた

たまに心は 揺れてしまう
窮屈な空を 見上げる瞳

溢れ出す願いと同じだけ 傷つきもするけど
振り向けば 夢のように青く
言葉にならなくても きっと この手 伸ばすよ 遠くへ
モノクロの虹が色を付ける そのとき
奇跡はもう はじまっている

涙といっしょに こぼれた気持ち あの日と同じ 心がリンクした
過去を脱ぎ捨て 未来(あす)を掲げて ページをめくれば 動き出すから
呼び掛ける青い鳥 本当は･･･私の中?

「忘れたことなんてないから･･･」
振り絞る声が いくつもの夢に光を灯す
叶えたい想いはずっとずっと 胸の深く深くで
飛び立てる瞬間(とき)を 息をひそめ 待ってる
解き放て カゴはもういらない

English Translation

A blue bird just like in fairy tales. I believed that it would bring me happiness.
Seeing it flying in the blue sky, I prayed that our feelings would overlap.

But someday it'll end up disappearing
Like a legend, turning into a hazy form.

I've never done something like forget, but as if I tripped and fell,
I go through and disappear like bubbles.
But even so, these feelings are always, always within my heart, deep deep within.
As if I'm sleeping, I conceal my breath and wait.
Set me free, I don't need a cage anymore.

Within the mirror that goes on forever, the happy me from that 日 reflected.
In the faraway sky of the world with no form, I searched for true warmth.

From time to time, my 心 ends up swaying
When I gaze at this narrow sky with my eyes.

It hurts just as much as an overflowing wish, but
If I look back, it's as blue as my dream.
Even if I can't put it in words, I'm sure I'll reach out my hand, no matter how far.
When a monochrome 彩虹 gets it's colors,
A miracle will begin.

That feeling that dripped together with teardrops linked with the same 心 as on that day.
I throw off the past and post up tomorrow, because if I flip through the pages, I will start to move.
Is the blue bird that calls me... Actually inside of me?

"I've never done something like forget, so..."
My strained voice turns on the light of dreams for so many people.
These feelings I want to make come true are always, always within my heart, deep deep within.
Ready to fly, I conceal my breath and wait.
Set me free, I don't need a cage anymore.
