The 100 series trains entered service on 1 June 1990 on Kegon and Kinu services from Asakusa in Tokyo to Nikkō and Kinugawa-Onsen, replacing the ageing 1720 series trains operating since 1960. Two sets were delivered in fiscal 1989, two more were delivered in fiscal 1990, and five were delivered in fiscal 1991, bringing the fleet to nine sets.[3]
All cars were made no-smoking from 18 March 1995.[1]
Through-running Spacia Nikkō and Spacia Kinugawa services from Shinjuku in Tokyo to Tōbu Nikkō and Kinugawa-Onsen via the JR Tōhoku Main Line commenced on 18 March 2006, and three sets (106 to 108) were modified with JR ATS-P for use on JR East lines.[3]
The fleet is scheduled to be refurbished from December 2011, ahead of the opening of the Tokyo Sky Tree in May 2012. Three trains each will be repainted into three different colour schemes, with purple, light blue, or orange matching the Tokyo Sky Tree theme colours, and new "Spacia" logos. Internally, the seats will feature new upholstery. The first refurbished set is due to enter service from 29 December 2011.[4]
