JR

JR, or Japan Railways, refers to the major railway companies that operate train services across Japan. Originally part of the National Railways, these companies were privatized in the late 20th century, leading to several regional JR companies like JR East, JR West, and JR Central. They provide extensive, reliable train networks that connect cities, towns, and rural areas, making travel efficient and convenient. JR is known for its high-speed train services, especially the famous Shinkansen, which can travel at very high speeds and are a key part of Japan's transportation infrastructure.
