Romanji Version:

RASSHU ni tobikondeku Monday
Ki ni iranai SUUTSU de Tuesday Wednesday
KOPII ni tsumazuite iru Thursday
Kirinuketa dake no Friday zutto

Machitsuzuketetemo
Shiawase no MEERU
Todoku hazu mo nai

Your sunny day
Carry the day kuchizusande
Nandaka hora karuku naru yo
Sagashite yumemite kotae dashite
Tokidoki um demo daijoubu
Eranda no wa watashi da mono

Aenai mama sugiteku Weekday
Kuuhaku ni natta manma no Saturday
Totsuzen karashi no TEL Sunday
Kuchi KENKA darake BAD na Holiday

Nakimushi keredo
Namida de kono machi
Sukitootte mieru

Your Sunny day
Have a nice day afuredashite
Yume no tochuu aruite mite
Makenaide nakanaide tayoranaide
Risou wo ima IMEEJI shite

Itsuka wa hora tsuyoku nareru
Makenaide nakanaide tayoranaide
Dare no sei demo nai

It's your life
Sagashite yumemite kotae dashite
Eranda no wa watashi da mono

Your sunny day
Carry the day kuchizusande
Nandaka hora karuku naru yo
Sagashite yumemite kotae dashite
Tokidoki um demo daijoubu
Eranda no wa watashi da mono

Translation:

Flying out of the house in a rush on Monday
Wearing a suit I hate on Tuesday, Wednesday
Problems with the copier machine on Thursday
Barely making it through to Friday, always
No matter how long I wait
There's really no chance
Or receiving my e-mail of happiness

Your sunny day, carry the day, try humming
See? It should get a bit lighter
I'll search, and dream, then give my answer
Sometimes, um, but it's alright
The one who chose was me

The weekdays fly by without us meeting
Then Saturday was just a void
Suddenly, he calls on Sunday
Spent a bad holiday, doing nothing but arguing

Though I'm such a crybaby
With these tears
I'll be able to see through the entire town

Your sunny day
Have a nice day, just overflowing
Try taking a walk halfway through that dream
Don't give up, don't cry, don't lean on anyone
Bring to mind your ideals
See? Someday, you'll get stronger

Don't give up, don't cry, don't lean on anyone
There's noone to blame, it's your life
I'll search, and dream, then give my answer
The one who chose was me

Your sunny day
Carry the day, try humming
See? It should get a bit lighter
I'll search, and dream, then give my answer
Sometimes, um, but it's alright
The one who chose was me
