The traction motors were replaced with new PMSM (permanent magnet synchronous motors), as used on the Chiyoda Line 16000 series sets, and internally, LCD passenger information screens were added above the doorways. The same was done to fifth-batch sets to over the next few years, and eventually all sixth-batch sets to by the end of May 2020.
