Happy birthday, happy birthday
Kyō kara no kimi no atarashī hibi ga
Kagayaku yō ni
Zuttozutto negai o komete
Akari o tomo shita nda

Kimigairu dakede kon’nanimo shiawase datte
Kidzuite shimau kidzuka sa rete shimau boku sa
Furui kioku mo ne atarashī kaze to tomoni
Umarekawaru mahō no kagi wa
Egao akeru no sa shiawase no doa o

Happy birthday happy birthday
Kinō made no kimi ga kyō kara no kimi e
Tsunaide yuku
Motto motto ōkina ai de tsutsunde

Tsutsuma rete kimi ga warau tabi kon’nanimo shiawase datte
Waratte shimau tsurarete waratte shimau yo
Sabishī hi kanashī hi namida-iro ni
Somatta yūhi o mite ita ne mahō no kagi no ari ka
Sagashi teta kimiwowasurenai

Kimigairudakede kon’nanimo shiawase datte
Kidzuite shimau kidzuka sa rete shimau boku sa
Kyandoru ni akari o tomosou hoshizora ni negaigoto o
Kaitanara kami hikōki de tobasu nda omedetō arigatō
Korekara mo yoroshiku I rabuyū mahō no kagi wa egao akeyou ne shiawase no doa o
