Tokyo has a reputation for being an expensive city.
While it may seem like there are no inexpensive travel options, there actually are quite a few.
When traveling around central area of Tokyo, the Tokyo Furii Kippu is an all-inclusive ticket good for the JR Railway, Toei Subway, streetcars, and buses, and the Tokyo Metro. It costs ¥1580 and is valid for a single day. It can be purchased at most major stations on the day needed or in advance.
Each rail line also has its own day pass as well.
