Transport in Tokyo
The different metro, train and bus lines efficiently connect the different areas of the Japanese capital.
If there's one city in the world where private transport is slower and less comfortable than public transport, that city is Tokyo.
Credit and debit cards are barely used, and nobody wants to carry cash to pay for each and every journey individually, meaning all native Tokians use pre-paid cards to pay for their public transport.
If you're planning to visit all of Japan and not just Tokyo, the Japan Rail Pass gives you unlimited rail travel.
