JR Narita Airport Station 成田空港駅 (8/97)
Tokyo has many good places to visit. And in general it is not difficult to go to such places without renting a car, because the public transportation system of Tokyo is convenient and accurate. You can take subways, JR commuter trains and the buses. However, I do not recommend taking the trains in the early morning (7am-9am) if you visit Japan for sightseeing, not for business; unless you want to have an experience to be almost killed in more than 300 people per one 20-meter passenger car.
