Happy Day Lyrics
[Romanized:]
Hey, you wanna make it a happy day?
Cause all we need is a happy day
OK alright
Sing it
Happy happy happy happy day
Happy happy (Take it, own it, make it)
Happy happy happy happy day
Happy happy happy happy day
Asagakita Rise and shine
Hajimeyou Another day of good vibes
Live in the now
Isshun de Energy wa taiyō yori mo higher
“Don’na hi mo Happy day” (Happy happy day)
Shinjitara, kanau ndakara!
(Let me tell you now
Let me tell you now)
Shout it out Kōun ga show up up up
Grooving -ha ni notte cruising
Imēji shite Walking, talking, laughing loud
Wherever you are
Say it’s a happy day
Make it a, make it a happy day
Say it say it say it aloud
Happy day iron’na kanjō
Roller coaster no yōna attraction
Ippun’ichibyō ga megahanasenai Crazy ride
Holiday matsu yori
Take it, make it something so special
Ī kibun ga Loop (That’s the sign)
We’re making it a happy happy happy day
Ooo it’s a happy happy day
Every day’s my happy happy day
Backstreet, it’s my stage
Aruku, soko ga Runway
Shōu~indou ni Strike a pose
Got a feeling yoi hi ni nari-sō
Woo wee risō no jibun ni
Chikadzuku yori “zettai sō naru!” No
