JR pass stands for Japan Rail pass. It is used to travel on trains within the network operated by the company. Thus it is very useful for tourists for exploring Japan.
When I was planning my Japan trip on the various sites to visit with the JR pass, my mate suggested that I write down all the information needed instead of just point A to point B, so that it would be easier when making the bookings at the JR station. When I reached Japan, I realized quickly what she meant.
There was a little language issue to overcome. But luckily with the details already written down, the process was quite smooth even with the language issue as the ticketing personnel simply followed the information I had written. So if you are going to reserve seats with the JR pass, maybe you would like to record the following information to pass to the ticketing personnel.
|date||train number||start point and time||end point|
