There have been plans at various points in history to connect Shinjuku into the Shinkansen network. Originally, the station was slated to be the southern terminus of the Joetsu Shinkansen line to Niigata. This plan was eventually scrapped, but an area was reserved underneath the station for Shinkansen platforms. In the future, the Chuo Shinkansen may bring high-speed rail service to Shinjuku.
