Shiroi katen no naka kirakira hairu hizashi
Mukumuku mega sameta kesa
Good morning radio DJ koubashii kohi no kaori
Kitto umaku iku yokanga suru
Nanka waraiga koborete shiawasena kibun
Kyowa kuji demo hiite miyo

Oh oh happy day oh oh happy smile
Oh oh happy sound oh oh happy life
Oh oh happy day oh oh happy smile
Oh oh happy sound oh oh happy life
Oh my happy day

Katani gitawo kake nanka karui ashidoride
Sekaino nakae hashiretara
Ohayou gozaimasu banira ice cream obaachan
Kyoumo shiawasena ichinichiwo
Purururu chakushin no oto senpai karano meru
Majide sorawo tonderu kibun

Oh oh happy day oh oh happy smile
Oh oh happy sound oh oh happy life
Oh oh happy day oh oh happy smile
Oh oh happy sound oh oh happy life
Oh my happy day
