Source : Nagai and Kobatake Songs (1892) / This song
dates to the Edo Period (1603-1867). ?Edo? is the old
name for Tokyo, and ?O-Edo? is an alternate form of
?Edo?. Yet another rendering of the city's name is
"Yedo". The Nihon Bridge used to be the last bridge
you crossed as you left Tokyo toward the south.
