Lyrics:

Thank you arigato
'Sayonara' is bye-bye
Thank you arigato
For a good, oh bye-bye
Don't leave anyone out
With gratitude bye-bye
Today and this day
Farewell, oh bye-bye
Even if it's tomorrow
Even if I can't see you
Today and this day
Farewell, oh bye-bye
Thank you good night
Thank you good night
Thank you good night
Thank you good night
Thank you arigato
'Sayonara' is bye-bye
Thank you arigato
For a good, oh bye-bye
Even if I'm alone
Make as if I'm happy bye-bye
Today and this day
For now it's bye-bye

Even if there's no tomorrow (There's no tomorrow)
Even if I get run over (I get run over)
Even if everyone dies (Everyone dies)
For now it's bye-bye
Thank you good night
Thank you good night
Thank you good night
Thank you good night
Goodbye goodbye
Goodbye goodbye
Goodbye goodbye
Bye-bye bye-bye
