While surfing the net for inexpensive travel in Japan I came across the Japan Rail Pass.
On further going through the internet I found that right here in Mumbai there is an agent that sells this pass. That was JTB Travels near Churchgate Railway Station. I approached them and provided the passport and ticket details. I got the best service from this travel agent. This is the right place to come to get your Japan Rail Pass which allows you to travel throughout Japan very cheaply and that too by BULLET TRAIN
