Kashiwazaki-Kariwa Nuclear Power Plant

The facility sits along the coast of the Sea of Japan, spreading across the boundaries of Kashiwazaki city and the territory of Kariwa village. Its seven reactor units stand in separate buildings connected by roads and open spaces between them.

Operations began in the late 1970s as Japan expanded its energy production. The Niigata earthquake in 2007 led to extensive inspections and structural adjustments throughout the site.

The power station represents Japan's commitment to nuclear energy development, featuring seven reactor units including the first advanced boiling water reactor worldwide.

The site is accessible to visitors only by prior arrangement and is subject to strict security controls. The surrounding communities have established warning procedures and evacuation routes.

The site was the first worldwide to operate an advanced boiling water reactor. Its combined output surpasses all other nuclear plants by electrical generation.
