Jibun yori chotto otonabite ita no ni
Tomadoi mo shita kedo dandan wakariaete kita ne

Wasureppoi kimi no koto dakara
Kenka ni mo naranai otagai nita mono doushi ne

Yuuguredoki no daisan keihin chairoi kabe no manshon mo
Machibouke baagaa shoppu zettai mata ikou

Kimi to zutto happy birthday deaeta kiseki wo
Boku nitotte happy birthday kokoro kara todoketai sankyuu

Omoide tsunaida omoi suutsukeesu
Kyandoru kazoete futari otona ni natteta ne

Amazuppai koi wo suru tabi ni
Wakari yasui mitai nazeka itsumo tonde kite kureru

Shinya sanji no denwa datte ashita mata au no ni
Uppun harashi shitai da nante uttoushii yo ne

Kimi to motto happy birthday mainichi ga kinenbi
Bokura zutto happy birthday itsumademo hanareta toshite mo

Futari nara zenbu wakeatte majime ni hashaidari
Tsurai koto mo tanoshiku shiyou dakara...

Kimi to zutto happy birthday deaeta kiseki wo
Boku nitotte happy birthday kokoro kara todoketai
Kimi to motto happy birthday mainichi ga kinenbi
Bokura zutto happy birthday kore kara mo douzo yoroshiku
Arigatou deaeta kiseki
