Day by Day, Asu wa kyō yori sukoshi.
Heiwa ni narimasu yō ni.

"Yume nara ba yokatta" toiu hi.
Dōnimo deki nai gekidō no nagare wo
Mi ni tsuyoku kanji nagara mo.
Ki wa utsuri shirazu~shirazu ni
Bokura no hibi mo kawari tsuzukeru.

Day bv Day Kibō sae miidasenai.
Mirai nante nokosenai.

Hi dakara koso wasurezu ni Day by Day.

Hi dakara koso wasurezu ni.
Day by Day Asu wa kyō yori sukoshi.
Heiwa ni narimasu yō ni...
