If you are going to sightsee in Tokyo, it might be better to purchase a train pass. Because the roads in Tokyo are crowded, rent-a-car is unsuitable. Also, I think that driving is more difficult for tourists who are not used to driving in Tokyo. Trains including the subway have many lines so it would be convenient to go anywhere. Especially the subway is complicated, but it is convenient so please try it.
Below is the main pass or ticket. Please refer it.
The posted information is as of 2017 October. Since it may be changed without notice, please confirm with the website of each company, or contact them.
Transportation system Ic card, Pasmo and Suica.
Transportation system IC CARD is convenient. Since it is mutually used nationwide, we can use it for the main railways and buses. There are Suica (JR) and PASMO (subway) cards, but both can be used in common.
How to use: IC card is charged in advance by ticket machines at a station, or at convenience stores. (1000, 2000, 3000, 5000yen) You touch the card on a ticket gate. It is a mechanism to automatically reduce the fare from IC card. Ticket gates will close automatically when the card shortage. It can be used not only in the metropolitan area but also in all available railway companies in the country.
