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 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
even if I get run over
even if everyone dies
for now it's Bye-Bye

Thank you good night
