ねえ教えて　どこから生まれてきたの　あたし
ねえ教えて　いつから続いているの　この世

わかると思ったことが
またまたわからなくなる
みわたせば　世界は
フシギなナゾであふれてる

わたしは　わたしが　わからない！

わからないから楽しいのよ
わからないから生きてゆくの
教えないで　教えないで　自分でさがすから
Mystery of Life！

どこから来て　どこまで歩いてゆくの　あたし
いつになれば　めぐりあえるのかしら　あなた

終わりと思っていたら
まだまだ先は遠いの
みわたせば　頂上
遥かかなたで光ってる

歩こう　歩こう　のぼりつめよう！

見えてないから楽しいのよ
見えてないから生きてゆくの
教えないで　教えないで　自分でさがすから
Mystery of Life！

Mystery of Life!

Hey tell me, where was I born from?
Hey tell me, how long has this world existed?

The things that I thought I knew
Again and again, I end up knowing them at all
When I look around, the world is
overflowing with strange mysteries

I, I don't know about myself

Because I don't know, it's fun
Because I don't know, I keep on living
Don't tell me, don't tell me, I'll find it on my own
Mystery of Life!

Where did I come from, and how far am I walking to?
When will the day come when I meet you by chance?

When I thought it was the end
There was still a long ways to go
When I look around, the summit
is shining far in the distance

Let's walk, let's walk, all the way to the top!

Because I can't see it, it's fun
Because I can't see it, I keep on living
Don't tell me, don't tell me, I'll find it on my own
Mystery of Life!
