The units entered service on 1 June 1988, and were originally painted in a livery designed by a Tochigi high school student, featuring large green "N" logos on a cream base. A new "retro" livery of brown and cream was introduced from March 2009, with the last train in original livery running until 17 January 2010.The 107-0 series sets were withdrawn from service on the Nikko Line on 15 March 2013.File:Jr-nikko-line107-0.jpg|107-0 series set N8 in original Nikko Line livery in June 2008File:20100727 Nikko Line 6133.jpg|Interior view in July 2010File:JRE107NikkoLineNewColor.jpg|107-0 series set N1 in revised Nikko Line livery in June 2009===Formation===The two-car 107-0 series trainsets, N1 to N8, were formed as follows with one motored car.
