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.
The holiday was excellent. It was arranged extremely well and all ran smoothly. We thoroughly enjoyed the cities we visited and were particularly impressed with the hospitality and civility of the Japanese. The train travel was great and the service was extremely efficient. I would strongly recommend the company and would definitely travel with you again.
