No, the Shinkansen (Bullet Train) does not stop at Shinjuku Station. Despite Shinjuku being the busiest railway station in the world, the high-speed Shinkansen tracks in Tokyo only serve Tokyo Station and Shinagawa Station. If you are staying in Shinjuku and need to catch a Shinkansen (like the Nozomi to Kyoto), you must first take a local train. The most efficient way is to take the JR Chuo Line (Rapid), which gets you from Shinjuku to Tokyo Station in about 14 minutes, or the JR Yamanote Line to either Tokyo or Shinagawa. In 2026, while there is ongoing talk about future "Linear Chuo Shinkansen" (Maglev) expansions, the current infrastructure requires all bullet train passengers to transit through the eastern or southern hubs of the city. Always allow an extra 25–30 minutes to navigate Shinjuku's massive corridors before your Shinkansen departure time.
