You found this post. Because you are overwhelmed by the train system in Tokyo, right? I understand it is very complicated because there are many train lines and many different railway companies. Actually it is very very hard to find the route for even the local tourist.
And also there are lots of deals available but you may not be able to find the coverage of the pass.
In this post, I will show you all subway lines and JR lines in downtown core of Tokyo. And I will also tell you about the train system surrounding in Tokyo too. Because some of trains that come from outside Tokyo go to downtown Tokyo via subway line. This is actually one of the reason why it is so difficult to understand train system in Tokyo.
If you will arrive in Narita and stay in Tokyo for several days, Suica & N’ex may be suitable for your stay. This ticket includes Narita Express ticket and 1500 e-money in IC card “Suica”. Suica can be used for both JR train and subways in downtown Tokyo. You can use this ticket for almost any trains when you stay in Tokyo.
I will tell you what this deal is and how to use it.
