Today, the high-speed network is managed collaboratively by different companies under the Japan Railways (JR) Group umbrella, including JR East, JR Central, JR West, JR Kyushu, and JR Hokkaido. Each regional company maintains its respective tracks, rolling stock, and station facilities, working together in close coordination to ensure seamless interline connectivity, immaculate safety records, and world-famous schedule punctuality across the entire national bullet train infrastructure.
