Access to the Shinkansen trains is on the Yaesu side. The ground floor level of Tokyo Station houses 20 train tracks at ten platforms. Two portions of the station are located underground, each housing four train tracks at two platforms.

Navigating Tokyo Station to find the Shinkansen (Bullet Train) tracks can be intimidating due to the station's massive size, but it is well-signed in English. First, look for the bright blue signs labeled "Shinkansen" or the specific line names like "Tokaido," "Tohoku," or "Hokuriku." If you are arriving via a local JR line (like the Yamanote or Chuo line), do NOT exit the station through the regular gates; instead, follow the signs to the "Shinkansen Transfer Gates" located within the secure area. If you are entering from the street, head toward either the Yaesu Side (East) or the Marunouchi Side (West) and look for the Shinkansen gates. The Tokaido Shinkansen (to Osaka/Kyoto) typically uses platforms 14-19, while the Tohoku/Joetsu/Hokuriku lines (to the North/West) use platforms 20-23. In 2026, you can use your Suica or Pasmo card at the transfer gates if you have pre-linked your ticket via the SmartEX app, or you can insert your physical paper ticket. Make sure to check the electronic boards for your train name (e.g., Nozomi #45) and car number, as the platforms are very long and you will want to stand at the correct boarding marker.
