History The 121 series sets were introduced on 23 March 1987, just nine days before JNR was privatised on 1 April, following which the 121 series fleet came under control of JR Shikoku. The sets were originally delivered with magenta "Red No. 20" bodyside stripes, but were repainted with JR Shikoku corporate light blue ("Blue No. 26") bodyside stripes during September and October 1987. In 1992, the original pantographs were replaced with the same S-PS58 type pantographs also used on the JR Shikoku 7000 series EMUs to ensure adequate clearance through tunnels on newly electrified sections of the Yosan Line. In 2011, two sets (numbers 001 and 002) were modified for ja-Latn wanman driver only operation. These sets were repainted with their original JNR-style magenta bodyside stripes.

Refurbishment included replacement of the DC motors with 140 kW AC motors and VVVF control, new side windows, new "efWing" CFRP bogies (S-DT67ef motor bogies and S-TR67ef trailer bogies), and a new livery based on the original style with a thin green line added to the magenta bodyside stripe.
