Kokoro no tobira o hirakou ima, jiyuu na yuuki de

Kitto surechigainagara kyou mo sasae rarete iru ne
Aa nemu sonna inu ni egao morattari

(I wish) moshimo jibun ga
(I think) tokidoki datte
(I can) dareka no chikara ni nare tetara
(Sou sa) sonna ureshii
(Zutto) rensa no naka de
(Konna) nante koto nai mainichi sae
Subarashii imi ga umareru

Kokoro no tobira o hiraite
Hirogaru keshiki wa it' s wonderland
Egao no ruupu de tsunagaru sonna bokutachi ga iru yo

Zenbu jibun no chikara de tadoritsuita you na kao de
ā Wakattenakatta katakuna ni natte

(For you) sashidashita te ni
(For me) riyuu sagashite
(For us) kekkyoku mitsukaranakutatte
(Sou sa) sore wa shizen ni
(Itsumo) tsutawatte iru
(Mou) yasashisa ni tere tari shinaide
Uketotta omoi to tomoni

Kokoro no tobira o hiraite
Mitsuketa sekai wa it' s brand new world
Chikara ga afurete kuru no wa kitto ki no sei janai
Tamerai wa senaka awase ni korekara mo ashibumi sareru
Sore demo yareru ki ga suru yo kimi ga yuuki o kureta ne

Kokoro no tobira o hiraite
Hirogaru keshiki wa it' s wonderland
Shirazu ni tasuke ai nagara itsuka kimi to mo deau
Kujike sou na toki wa oide yo hitori de kakaekomanaide
Egao no ruupu de tsunagaru sonna bokutachi de iyou
Kyou mo yuuki o kureru yo
