This is a simple tip about renting a car to see metropolitan Tokyo.
Don't bother.
Though Tokyo is a huge and modern city, the streets are not well laid out for automotive travel. Not to mention the fact that many narrow streets don't have any names. This can make it a real nightmare for a tourist trying to get around.
The public transit system is incredible, with a wide network of subways, trains, and buses. Get a good map of the subway and train system, because there are several lines that include more than one private rail system. You'll never wait very long for the next train, and they will take you any place you'd want to go.
