虹 (pronounced as "Niji", translated as "Rainbow") is found Kobukuro's 17th single (虹) and 7th album (CALLING). I really like the lyrics to this song, especially since they are vivid like a rainbow. Starting this post, I will italicize the changes I made in the revised versions of my translations.
~~~~~Kanji
閉じた傘の先っぽで
曇り空なぞったアーチ
このくすんだ世界に
誰か素敵な色を足してくれないか？
雨上がりの街に
飛び交う 希望の粒子を
吸い込んだ春の日差しが
集めた 七色のイオン
もうすぐ君は 旅立ちの時
その心 締め付ける
不安や迷いを 解（ほど）く
光のような
言葉 僕は
見つけられるのかな？
遠ければ遠いほど 鮮やかな虹の色
心の果てに 描いた夢は 今も
夢のまま
近づけば近づくほど
見えなくなってゆくけれど
消えたんじゃない
光の中に 君は 今 包まれているから
３色のクレヨンで 何だって描けたのに
１００色の絵の具 目の前に
被写体が決まらない
この瞳が忘れた色 探して
屋上で一人眺める空に
愛よりもっと深い 夢より強い
色を 僕等
見つけられるのかな？
遠くまで届くのは
悲しみ越えたメロデイー
瞳 閉じれば
心のドアとドアで
繋がってる
いつまでも忘れない
喜び満ち溢れた日々
消えたんじゃない
記憶の中に 君との想い出並べ 生きてる
遠ければ遠いほど 鮮やかな虹の色
心の果てに 描いた夢は 今も
あの虹のように 掴めぬまま
近づけば近づくほど 見えなくなってゆくけれど
消えたんじゃない
光の中に 君は 今 包まれているから
ただ一筋の願いが
無限の想いを乗せて
透明な 虹をかけてる
曇り空なぞったアーチ
このくすんだ世界に
誰か素敵な色を足してくれないか？
雨上がりの街に
飛び交う 希望の粒子を
吸い込んだ春の日差しが
集めた 七色のイオン

不安や迷いを 解（ほど）く

English translation (first draft)With the end of this closed umbrella,
I traced an arch in the cloudy sky
Can't someone add beautiful colours to this dull world?
In the town after the rain
The particles of hope flutter about
Absorbing the sunlight of spring
and collecting the ions of the seven colours
Soon enough, that heart tightens when it's time for you to leave
Things like anxiety and doubt will be released
Words like light
Will I be able to see them?
As far as it could go
Brilliant colours of the rainbow
At the bottom of my heart,
I drew dreams that are now still just dreams
The closer you go towards it, the harder it is to see it
But it's not gone
Now you will be wrapped in the light from now on
Despite whatever you have drawn with only 3 colours of crayons
The tools to create a drawing with 100 colours are in front of your eyes
and the subject could change
These eyes search for the forgotten colour
Alone on the rooftop, gazing at the sky
Deeper than love, Stronger than dreams
Will we be able to see the colour?
Reaching as far as it could
The melody that overcomes sadness
If you close your eyes
The doors of the heart will connect
Never forget the days overflowing with joy
They won't disappear
My memories with you are arranged in my memories,
they will live on
As far as it could go
Brilliant colours of the rainbow
At the bottom of my heart,
I drew dreams that are now still
Like that rainbow you can't grasp
The closer you go towards it, the harder it is to see it
It won't disappear
Now you will be wrapped in the light from now on
An infinite amount of feeling ride on
just one ray of wishes
Building a transparent rainbow

The particles of hope flutter about
Absorbing the sunlight of spring
and collecting the ions of the seven colours
Soon enough, it'll be time for you to leave
Your heart tightens with things like anxieties and doubts
Will I be able to find the words similar to light that will release them, i wonder?
As far as it could go
Brilliant colours of the rainbow
At the bottom of my heart,
I drew dreams that are now still just dreams
The closer you go towards it, the harder it is to see it
But it didn't disappear
because you are now wrapped in the light
You could have drawn anything with 3 colours of crayons,
however with 100 colours to choose from in front of your eyes,
you can't decide what to draw
My eyes search for the forgotten colour
while gazing at the sky alone on the rooftop
Will we be able to find the colour that is
Deeper than love, Stronger than dreams, I wonder?
The melody that overcame sadness
reached as far as possible
