Sukoshi hayaku mezameta asa
Itsumo yori mo daibu otoku
Asa no shawaa bacchiri kimete
Kyou wa doko ni ikou ka na
Kumori sora wa otokuisama da yo
Datte ao ga suketerumon
Kitto sugu ni kao wo dasu hazu sa
Ohisama puriizu

Sukoshi hayaku kaetta yoru
Itsumo yori mo daibu otoku
Ichiban furo yuuga ni kimete
Asu wa dare ni deau ka na
Acchi no umi amakunaku datte
Uki shizumi ni ukiwa tsukete
Fuwari fuwari kyuukei shitara
Sumairu puriizu

I know sumairu houteishiki
Boku no kotae wa imozuru happii
I know sumairu houteishiki
Kimi no suteki na waraigao wo misete yo
Sukoshi mukou te wo futteiru
Itsumo yori mo daibu genki
Donna toki mo hitori ja nai
Kimi wo miteru hito ga iru

Aa shinakerya kou shinakerya to ka
Sonna koto wo dare ga kimeta?
Aru hi kyuu ni wakaru hi ga kuru sa
Okiraku puriizu
I know sumairu houteishiki
Boku no kotae wa imozuru happii
I know sumairu houteishiki
Kimi no suteki na waraigao wo misete yo
