This plant was once said to be the closest nuclear power plant to a prefecture capital. However, on March 31, 2005, the area of Kashima-chou merged with Matsue (it was formerly in the Yatsuka District), making it exactly the same city as the prefecture capital.

New Scientist magazine has reported that, in June 2006, a previously unknown geological fault was identified close to the Shimane Nuclear Power Plant, but it is expected to be years before the plant is strengthened.[1]

The power plant covers an area of 1.92 square kilometres (470 acres).[2]
