How to get around Tokyo
In Tokyo, you can hail a cab on the street or catch taxis from the stands located in front of train stations. Taxis have GPS systems installed, but many drivers don't speak English. Catching taxis in general in the city is not cost-effective, unless you're travelling in a group. Because traffic can be heavy, fares can increase quickly too.
Tokyo Public Transport
It's well worth making trains your primary mode of transport in the city, as they are reliable and economical. For unlimited use of the train system, purchase a Japan Rail Pass. Train lines include kakueki-teisha or futsu-densha (local), kaisoku (rapid), kyuko (express) and shinkansen (super express). If a train isn't available where you are in Tokyo, the area will more than likely be served by a bus or ferry.
Tokyo Bike Hire
While there aren't many bike lanes in the city, it's still a great way to get around and gain an understanding of Tokyo's layout. Some Japanese retail companies and many guesthouses provide bike hire services.
Tokyo is a safe city, so it's a great place to explore on foot. Put on a pair of good shoes and take a stroll along the capital's streets and through its many beautiful parks. Some trails have even been specially mapped out for visitors. These are worth looking into, as they'll allow you to discover poignant moments in the city's history.
