In June 2016, JR East announced plans to rebuild the station ahead of the 2020 Olympics in order to alleviate overcrowding. A new station building was to be built by JR East at the station's Meiji-Jingu entrance. A temporary platform used during busy periods will become the permanent platform for trains heading north through the station. The new station building and platform opened on 21 March 2020, in time for the Tokyo Olympics and Paralympics. JR East decided in November 2019 to demolish the old station building at the Takeshita entrance on safety grounds after the Paralympics, and replace it with a safer structure constructed in a similar style.
