I’ve owed my friend this one for a long time and thankfully I remembered again so I could do it. 40mP is well known for some of his beautiful duets like Futari Boshi, Hokorobi, and Melody in the Sky, but Happiness Index is another beautiful Miku/Gumi piece that headlined one of his Douji albums known as Happiness Index (幸福指数/Kofukushisuu). You can still buy the album on Amazon JP and Toranoana. Some other well known songs on the album include Eyesight Test, Parameter, and The Town Closest to Spring. Below will be the Kanji, English and Romaji lyrics. As always be sure to let me know if any revisions need to be made.
どんなに些細な出来事でも
No matter if it’s the most trifling of things
Donna ni sasai na dekigoto demo
二人で分かち合うだけで、ほら
Just by sharing that moment together, look
Futari de wakachiau dakede hora
１＋１の裏側にある
On the other side of “1+1”
Ichi tasu ichi no uragawa ni aru
本当の答えが見えてくるでしょ
The truth of us comes into view
Hontou no kotae ga mietekuru desho
輝く星の数 飲み込む言葉の数
Equal to the shining stars in the sky, the number of words we take in
Kagayaku hoshi no kazu nomikomu kotoba no kazu
マイナス思考の毎日も 二人でいればプラスに変わる
Those negative everyday feelings…when we’re together they become something positive
Mainasu shikou no mainichi mo futari de ireba purasu ni kawaru
貴方が笑った回数と 私が笑った回数を
The number of times you laugh, the number of times I laugh as well
Anata ga waratta kasuu to watashi ga waratta kaisuu wo
掛け合わせると見えてくるよ 二人の幸福指数
If you multiply them together, it can be seen, our very own “happiness index”
Kakeawaseru to mietekuru yo futari no koufukushishuu
貴方が笑えないときは 私が笑ってあげるよ
At those moments you can’t laugh, I’ll smile and cheer you up
Anata ga waraenai toki wa, watashi ga waratteageru yo
泣き顔したお星さま 二人の笑顔で笑顔になるよ
Even the tear-stained faces of the stars in the sky brighten up at the sight of our smiles
Nakigao shita ohoshisama futari no egao de egao ni naru yo
例えば貴方が悲しいときに
Whenever you are sad
Tatoeba anata ga kanashii toki ni
流れるその涙拭い去るより
Rather than just wiping away those tears you shed
Nagareru sono namida nuguisaru yori
貴方と同じ数の涙を流せる
I want to cry the same number of them
Anata to onaji kazu no namida wo nagaseru
そんな私でありたい
That’s the kind of person I want to be for you
Sonna watashi de aritai
限りある悲しみに限りない微笑みを
Into that limited amount of sadness, an unlimited number of smiles
Kagiriaru kanashimi ni kagirinai hohoemi wo
割り切れない毎日も 二人でいれば乗り越えてゆける
Within those indivisible days, as long as we’re together, we can overcome anything
Warikirenai mainichi mo futari de ireba norikoete yukeru
切り取った言葉が紡ぎ出す愛の歌
Those cut out words come together to form a love song
Kiritotta kotoba ga tsumugidasu ai no uta
幸せの数だけ口ずさむ愛の歌
A love song hummed along to the number of our shared happiness
Shiawase no kazu dake kuchizasamu ai no uta
私から貴方へ届かせてよ愛の歌
A love song I want to reach from me to you
Watashi kara anata he todokasete yo ai no uta
貴方から私へ聞かせてよ愛の歌
Let me hear it, that love song from you to me…
Anata kara watshi he kikasete yo ai no uta
貴方が笑った回数と 私が笑った回数を
The number of times you laugh, the number of times I laugh as well
Anata ga waratta kasuu to watashi ga waratta kaisuu wo
掛け合わせると見えてくるよ 二人の幸福指数
If you multiply them together, it can be seen, our very own “happiness index”
Kakeawaseru to mietekuru yo futari no koufukushishuu
貴方が笑えないときは 私が笑ってあげるよ
At those moments you can’t laugh, I’ll smile and cheer you up
Anata ga waraenai toki wa, watashi ga waratteageru yo
泣き顔したお星さま 二人の笑顔で笑顔になるよ
Even the tear-stained faces of the stars in the sky brighten up at the sight of our smiles
Nakigao shita ohoshisama futari no egao de egao ni naru yo
二人の愛は無限大だよ
That love of ours is infinite
Futari no ai wa mugendai da yo
