JRPass

Hi Fabio,

The Rail Pass can be used on JR lines in Tokyo, the most useful of which is the JR Yamanote line, which is a loop that travels through Tokyo. Here is a map of JR lines in Tokyo you can use with the rail pass.

The JR Pass cannot be used however on the Metro/subway, which is operated by a private company. The subway is pretty cheap, and you can ride it using either separate tickets or a prepaid card called Pasmo or Suica (there are 2 types of prepaid card).

You can find more about using the subway here and the pasmo/suica prepaid metro cards here.

Hope this helps!
