- [Chorus]
- HJ5, HJ5, HJ5 will come alive
- Kuu Kuu Harajuku
- (Come on now)
- HJ5, HJ5, HJ5 in overdrive
- Kuu Kuu Harajuku
- (Come on now)
- HJ5, with your style
- Kawaii makes love worthwhile
- Kuu Kuu Harajuku
- (Come on now)
- [Verse 1]
- Say hello to HJ5
- A brand new band with their own style
- To the stage, they rock a tour
- Friends for life, you know for sure
- Energy with fantasy
- That's the Kuu Kuu mentality
- In harmony they dance and sing
- So stand up tall and do your thing
- [Interlude]
- Love, Angel, Music, Baby
- And G, Kawaii
- Love, Angel, Music, Baby
- And G, super Kawaii
- [Verse 2]
- Alright
- Line up girls
- Kuu Kuu roll call
- Five-six-seven-eight
- Love is the brain of the crew
- Invent like mad to help the squad through
- Angel here with the sunshine demeanor
- Come to her if you need a cheerleader
- Music, you better watch her fight
- You cross her crew she'll put up a fight
- Baby, sweet as can be
- Loves hugs and pugs, anything kawaii
- Then there's G, the leader of the pack
- You need a friend, she's got your back
- You need a friend, they got your back
- Come on girls, come on let's get it
- Come on girls, come on let's hit it
- Five friends, one band
- And like a billion fans
- [Interlude]
- Love, Angel, Music, Baby
- And G, fit perfectly
- With style, grace
- They rock this place
- Contracts, rock tracks
- Up in your face
- Uh huh, here we go
- Tick-tock, time to rock
- Three-two-one, sing
- [Chorus]
- Kuu Kuu Harajuku
- (Come on now)
- HJ5, HJ5, HJ5 will come alive
- Kuu Kuu Harajuku
- (Come on now)
- HJ5, HJ5, HJ5 will come alive
- Kuu Kuu Harajuku
- (Come on now)
- 1-2-3-4, HJ5
- [Outro]
- That was super kawaii
