Yakusoku wa nandodatte
Hora egao wa bokura dake no engage
Moratta yasashisa no ookisa de
Agetai yo kandou o kondo wa surprise

Soushite mitsukete kou saikou no days
Kyou ni tadoritsuita you ni ne issho ni
Yume no basha ni wa kimi to noru yo
Kawaranai decided zutto!

Keep on smiling place!
Ima chikau yo kazoekirenai shiawase ageyou
Forever smiling place!
Kono omoi o katachi ni shite utaou

Tomorrow diamond
Tatoeba tonari ni irarenakutemo
Negatteru yo sono hitomi no happiness
Mujaki ni waratte kureru dake de

Kyou o ganbaru yuuki mune ni tomoru yo
Yume no mahou wa kimi o tsurete
Tobitatou saite miyou bouken shiyou
Dramatic nemuru asu e!

Happy smiling dream!
Hajimari no hi me to me awase te o totta darou?
Forever smiling dream!
Onaji nanda toki o koete okurou

Tomorrow diamond
Come on, shall we dance
Tamani wa hashaide
Come on, shall we dance

Chigau kimi o misete
Show time endless!!!
Yakusoku wa nandodatte
Hora egao wa bokura dake no engage

Keep on smiling place!
Ima chikatta kimi to sugosu shiawase daite
Forever smiling place!
Kono omoi o katachi ni shite utaou

Tomorrow diamond
Sekaijuu ga furimuku
Tomorrow diamond
