The Japan Rail Pass (ジャパンレールパス, japan rēru pasu), also called the JR Pass, is a rail pass for overseas visitors sold by the Japan Railways Group, and is valid for travel on all major forms of transportation provided by the JR Group in Japan, with a few exceptions. The Rail Pass is designed to stimulate travel and tourism throughout the country. It is only cost effective for long-distance travel, particularly by bullet train. While the savings from extensive travel can be considerable, those who travel too little may in fact lose money on a rail pass. The Japan Rail Pass is of limited use within larger cities, as private operators generally do not accept the Rail Pass. In Tokyo, for instance, it covers the Yamanote Line which goes to several popular tourist areas, as well as in Osaka on the Osaka Loop Line, plus in Kyoto on the Nara Line and Sagano Line.
