Rebuilding
The sets were rebuilt from surplus former 581/583 series EMU cars at JNR factories in Tsuchisaki (Akita), Kōriyama (Fukushima), Mattō (Ishikawa), and Kokura (Kitakyūshū). Rebuilding work involved removing the upper sleeper berths, adding longitudinal bench seating at the ends of cars, increasing the number of doorways, reducing the number of toilets and washing areas, and the addition of slab-front cab ends to some former intermediate cars.[1]
