東京晴空塔
The fleet underwent a programme of refurbishment from December 2011, ahead of the opening of the Tokyo Skytree in May 2012. Three trains each were repainted into three different colour schemes, with "miyabi" purple, "iki" light blue, and "sunny coral orange", matching the Tokyo Skytree theme colours, and new "Spacia" logos. Internally, the seats feature new moquette, with blue in the open saloons and brown in the compartments. The first refurbished set re-entered service from 29 December 2011.
