The reactors for units 1 and 3 were supplied by Toshiba, and for units 2 and 4 by Hitachi. Units 1–3 were built by Kajima while the unit 4 was built by Shimizu and Takenaka. The design basis accident for an earthquake was between 0.42 g (4.15 m/s²) and 0.52 g (5.12 m/s²) and for a tsunami was 5.2 m.
