The Japan Rail Pass (also commonly called JR Pass) is a nationwide rail pass for long-distance train travel in Japan.
The pass can be used only by foreign tourists and offers unlimited rides on JR trains for one, two or three weeks. It comes in two types: ordinary and green car. The latter is valid on green cars (first class cars), which offer more spacious seats than ordinary cars.
The pass lost a lot of its appeal due to a massive price increase in autumn 2023, but it remains a worthwhile product especially to those who do not mind paying extra for the convenient all-you-can-ride privilege, which frees one from having to buy individual tickets for each ride.
