The Japan Rail Pass is a special ticket that allows unlimited travel on most trains operated by Japan Railways (JR) across Japan. It is available for foreign tourists and can be purchased for durations of 7, 14, or 21 consecutive days. The pass covers various train types, including the famous Shinkansen (bullet trains), making it a convenient option for exploring the country. To use the Japan Rail Pass, travelers must first buy an exchange order before arriving in Japan. Once in the country, they can exchange this order for the actual pass at designated JR offices. The pass also offers discounts on certain buses and ferries, enhancing travel flexibility.
