The Tokaido road is the
road in
Japan that connects
Kyoto with
Tokyo. It is
historically significant for many reasons, but the
fact that the two most important cities in
Japanese history are at either end of it should be reason enough. Many a
daimyo and his
entourage has made the
journey down the Tokaido, especially during the
Tokugawa era.
I think it's a freeway, now.
