I will be travelling to Japan for approximately 12 days in April.
I wil begin by travelling from Narita to Yokohama on my first day (Friday morning). Then I will be travelling around the Tokyo and Yokohama area for the weekend. On the first Monday I will travel to Sendai. I will have some days just in Sendai, but expect to spend other days travelling on day trips north and south until my final day when I will travel back from Sendai to Tokyo and finally back to Narita for my flight home in the evening of the last Tuesday.
My question is...which pass is best for me. I note in your coditions that you can only purchase one pass, yet in your answers I see you tell people that it is ok to purchase multiple passes.
Is it possible to purchase a JR East 4 day flexible pass and then a 3 day flexible pass? Or would it just be easier to purchase a 14 day overall pass?
