The Shimane Nuclear Power Plant (島根原子力発電所, Shimane genshiryoku hatsudensho, Shimane NPP) is a nuclear power plant located in the town of Kashima-chou in the city of Matsue in the Shimane Prefecture. It is owned and operated by the Chūgoku Electric Power Company.

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]
