SHA LA LA Some day in the future I will, for sure, hold it in my hand Let it softly set ablaze A light in your empty heart.

The "impulses" of wanting to meet you, the "innocence" of wanting to cry, the fireflies have gone into the blaze of the summer to never come back again.

You remained silent and left me a kiss, pained and hurt, I nodded my head. your life flickered like a light, it was so sad.

SHA LA LA Some day in the future, I will, for sure, hold it in my hand. let it softly set ablaze A light in your empty heart.

SHA LA LA My sweet, lovely dear, I can see you too now. The dazzling moon will softly, Illuminate the morning day.

Strongly, strongly shine on.

SHA LA LA いつかきっと 僕は手にするんだ はかなき 胸に そっと ひかり 燃えてゆけ

逢いたくなるの「衝動」哭きたくなるの「純情」 夏の火に飛び込んだ ホタルはかえらない

あなたは何も言わず接吻(くちづけ)を残して 火傷(きず)つくまま うなづいたね 哀しいほど命 揺らめいていた

SHA LA LA いつかきっと 僕は手にするんだ はかなき 胸に そっと ひかり 燃えていけ SHA LA LA 愛しきひと あなたもみえているの まばゆい 月が そっと 明日を照らして 強く 強く 輝いて

風に吹かれるほど 烈しくなる心に はぐれそうな想い出が また優しく灯る

夢中で駆けだしたら 触れられる気がした 意志(おもむく)まま 手を伸ばすよ 切ないほど命 揺らめいてゆく

SHA LA LA 僕はずっと 唄いつづけていくよ ふるえる 胸に そっと ひかり 燃えてゆけ SHA LA LA 愛しきひと あなたに届くように はてない 空に そっと 想い つのらせて 強く 強く 響かせて

SHA LA LA いつかきっと ホタルは燃え尽き散って きえゆく 胸に そっと 夢よ 輝いて SHA LA LA 愛しきひと あなたも忘れないで きらめく 夏に そっと 願いを重ねて

SHA LA LA いつかきっと 僕は手にするんだ はかなき 胸に そっと ひかり 燃えていけ SHA LA LA 愛しきひと あなたもみえているの まばゆい 月が そっと 明日を照らして 強く 強く 輝いて

Sha la la I know that someday. I'll find what I'm running after. Let the light shine in your empty heart. and set your soul ablaze.

The desire to see you again is so pure it makes me weep. The fireflies have flown off into the summer sky never to return.

You left me with a silent kiss goodbye and hurt and upset, I still nodded my head left alone, trembling and sad.

Sha la la I know that someday. I'll find what I'm running after. Let the light shine in your empty heart and set your soul ablaze.

Sha la la Oh my beloved. I can still see your safe. as the moon's dazzling light illuminates the next day shine strong, shine strong!
