Machi made ichiban chikai KO no ie ni
Sawagashii heya wa shiroi kemuri no BARIAA
Owaranai saishuu CHEKKU kagami no ubaiai
Saigo no natsuyasumi no HONTO no imi shirazu

Issei ni tobidashitara gunjou no yuuyami ga
Hosoku nokotta taiyou to watashitachi to tsutsumu

* Itoshii Oh! Happy days. Ano jikantachi wa ryoute ni ippai no
   Itoshii Oh! Glory days. Takara no arika wo shirushita chizu

Kossori uwabaki no mama kyoushitsu nukedasu
Ushiro ni HANE ga mizutama tsuketa uramichi

Konayuki no samui yoru mo tokedashita koori no ike mo
Ude o kunde onaji keshiki toorisugite kita

Itoshii Oh! Happy days. Ano jikantachi wa bouken mo warai mo
Itoshii Oh! Glory days. RAVU SUTOORII mo aru HITTO FIRUMU

Kore kara machiukeru subete no dekigoto ga
Watashitachi min'na wo HAPI na ketsumatsu e michibite kureru you ni

* repeat

Itoshii Oh! Happy days. Tokidoki hirogete sotto mabuta tojiru
Itoshii Oh! Happy days. Takaramono wa anatatachi no egao

Itoshii Oh! Happy days.
Itoshii Oh! Glory days.
