Nine sets were delivered to Minami-Fukuoka depot in 1994, originally as two-car sets, entering service from 1 March 1994. From March 2003, new 10th-batch SaHa 813-400 centre cars were added to standardize the entire fleet as three-car sets. These sets are normally used on the Kagoshima Main Line, Nippō Main Line, Nagasaki Main Line, and Sasebo Line. Two-car set R008 was withdrawn together with R101 and R231 after sustaining damage in a head-on collision in February 2002.
