Wakaranai tte ienakatta
Nazeka hohoemi ga tomaranai no kanashii noni
Sore wa mushiro anata no hou ga
Iki ga tsumaru hodo watashi wo mitsumete ita kara

Makesou na toki wa boku no tegami wo yonde koe dashite

Hareta hi mo naita hi mo saite ita
I say hello to nichi-nichi-so
Aitakute aenakute girigiri de
I say good-night to nichi-nichi-so

Shiranai kuni ni totsuzen maiorita you na
Kitai to fuan de ha-fu and ha-fu
Anata nashi no hibi ni narete tsuyoku naru koto ni
Teikou shite matte iru yo

Natsu to tomo ni satte ichinengo kaette ne big wave

Hareta hi mo naita hi mo saite ita
I say hello to nichi-nichi-so
Aitakute aenakute girigiri de
I say good-night to nichi-nichi-so

Muimi na hi nante nai kyou mo mata
I say hello to nichinichiso
Mekurumeku shiawase ga kuru hi made
I say good-night to nichi-nichi-so

Aa kare ga satta hi no mama ni ratan no sofa ni nekorobu neko jarashi
Ready to play

Hareta hi mo naita hi mo saite ita
I say hello to nichi-nichi-so
Aitakute aenakute girigiri de
I say good-night to nichi-nichi-so

Muimi na hi nante nai kyou mo mata
I say hello to nichinichiso
Mekurumeku shiawase ga kuru hi made
I say good-night to nichi-nichi-so
