The JR Pass is a special pass available only to those entering Japan on a tourist visa. It allows for unlimited travel around Japan on JR lines usually at a price much less than purchasing individual tickets.
Excellent service regarding the JR in general and also excellent value for money. Food and sites to visit all first class. Must be the cleanest country in the world, regardless of the total absence of the street litter bins! Exceptionally friendly people further enhance the experience.
