Tokyo train route finder

Planning to travel around Tokyo? Here’s a tip that will save you a lot of grief trying to find the right train. With all the city’s 121 rail lines a decent map is essential but if you want to plan ahead, an online train route finder is a very reliable way of scheduling your trip.
Japanese people often use this train route planner from Yahoo! Japan but it’s useful only if you understand Japanese. So how can an average gaijin find his way around?
Tokyo Transfer Guide is a very handy tool in English that lets you plan your trip by station number or station name within the Greater Tokyo metropolitan area. The results which you can print out can be viewed by travel time, cost of fare and number of transfers.
Similar train planners in English are TrainRouteFinder by Jorudan Co. and Hyperdia.

I lived in Japan for 3 years…everywhere I went, I used Hyperdia. Keitai access, too. :)
