Kyou to iu hi
kimi ga koko ni kita hi
subarashii hi
minna ga egao de iru hi

MAMA no atatakai ai no naka de naita
PAPA no ooki senaka ni tsutsumare nemutteta

"Ashita mo genki de imasu you ni"
"ookiku narimasu you ni"
hibi negattete kureteta kara
kimi wa koko ni irun da yo

HAPPY HAPPY BIRTHDAY FOR YOU
kyou no shuyaku wa kimi dakara
ippai kakae kirenai shiawase o kanjite

Saikou no kinenbi o
saikou no egao de kimeyou
kyou kara mata hajimaru
atarashii kimi e no SUTAATO

Nakimushi de yowamushi de amaeteta
itsu no ma ni ka "ohayou" mo ienaku natta

Itsumo soba de mimamotte kureteta
dare yori mo kitto rikai shite kureteta kara

Ki ga tsukeba anata to deatte
kizukeba suki ni natteta
dakara kyou wa hitokoto iou "umarete kite arigatou"

HAPPY HAPPY BIRTHDAY FOR YOU
anata kara watashi e okuru
ippai kakae kirenai shiawase uketotte

Saikou no kinenbi o
saikou no egao de sugosou
kyou kara mata hajimaru
atarashii mirai e no SUTAATO-RAIN!

Ironna hito ni sasaerarete kita sekaijuu daremo ga onaji dake no "omedetou"

HAPPY HAPPY BIRTHDAY FOR YOU
kyou no shuyaku wa kimi dakara
ippai kakae kirenai shiawase o kanjite

Saikou no kinenbi o
saikou no egao de kimeyou
kyou kara mata hajimaru
atarashii kimi e to

HAPPY HAPPY BIRTHDAY FOR YOU
watashi kara anata ni okuru
ippai kakae kirenai shiawase uketotte

Saikou no kinenbi o
saikou no egao de sugosou
kyou kara mata hajimaru
atarashii mirai e no SUTAATO
