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.
Japan is a magical place. The way Shinto, Buddhism, and lively capitalism coexist side by side is often breathtaking. The trains are wonderful, and the food simply amazing. I had a truly unforgettable experience, and would love to go again.
