Ohitsuji, Oushi, Futago, Kaniza
Shishiza ni Otomeza, Tenpinza
Sasoriza, Iteza, soshite Yagiza
Mizugame, saigo ni Uoza

Watashi ga umareta sono yoru ni
Mama wa ureshikute naitatte
Itsumo kurikaesu hanasunda
Shiawase na omoide da to

Haru natsu aki fuyu meguri kuru
Ichinenjuu no subete no hi ga
Mainichi dareka no tanjoubi
Oiwai shiyou yo Happy birthday

Papa no papa no sono mata papa ya
Mama no mama no sono mata mama ga
Ita kara koko ni watashi ga iru
Nante suteki na ohanashi

Anata ga umareta sono toki mo
Yasashiku hohoemu hito ga ita
Atarashii inochi mata hitotsu
Yorokobi hakonde kuru yo

Ichinen sanbyaku rokujuu go
Donna ni chiisana ichi nichi mo
Mainichi dareka no tanjoubi
Kakegae no nai taisetsu na hi

KEEKI ga nakutemo ki ni shinai
PURENZENTO nakutemo kamawanai
Ame demo yuki demo iyanai
Asu mo asatte mo Happy birthday

Ohitsuji, Oushi, Futago, Kaniza
Shishiza ni Otomeza, Tenpinza
Sasoriza, Iteza, soshite Yagiza
Mizugame, saigo ni Uoza

Minna no minna no Happy birthday
Mainichi dareka ni Happy birthday
Otanjoubi omedetou To you
