Tokai village in Ibaraki Prefecture is well known as the birthplace of nuclear power in Japan.  The Japan Atomic Power Co. began construction of Japan's first commercial nuclear power plant in Tokai  village in 1960. Tokai Power Station was completed in 1966, and then Tokai-II Power Station entered commercial operation in 1978.  The first of these discontinued service in 1998.

Electricity produced from Tokai-II power station is transmitted and distributed, through utility companies in the Tokyo and Tohoku service areas, to industrial, commercial and domestic users, thus helping greatly to balance the supply and demand for power in Japan.
