History The area around Rokkasho was known for raising horses during the Kamakura period. During the Edo period, it was controlled by the Nanbu clan of Morioka Domain, becoming part of the territories of Shichinohe Domain in the latter half of the Edo period. With the establishment of the modern municipalities system after the start of the Meiji period, on April 1, 1889, the village of Rokkasho was created following the merger of six small hamlets.

From the 1980s onwards, the village has become a centre for various energy developments, which now dominate the local economy.

Nuclear industry & Research Nuclear fuel cycle related facilities: • Japan Nuclear Fuel Limited headquarters • The Rokkasho Reprocessing Plant (currently under test operation) • A uranium enrichment plant and plutonium reprocessing plant. • A MOX fuel fabrication facility with an 800-ton per year capacity when completed • A low level nuclear waste storage facility • A high level nuclear waste temporary storage and monitoring facility

The Japan Atomic Energy Agency also has multiple facilities at the site like the Linear IFMIF Prototype Accelerator (LIPAc) devoted to the Fusion Energy Development Programme under the European Union-Japan Broader Approach agreement.

Since the 1970s, local opposition to plans to operate Japan's first large commercial plutonium plant at Rokkasho have focused on the threat of a large-scale release of radioactivity. During the 1990s anti-nuclear groups in Japan released studies showing the risks of routine operation of the Rokkasho Reprocessing Plant. The facility in full operation is designed to separate as much as 8 tons of plutonium each year from spent reactor fuel from Japan's domestic nuclear reactors. As of 2006 Japan owned approximately 45 tons of separated plutonium.

In May, 2006, an international awareness campaign about the dangers of the Rokkasho reprocessing plant, Stop Rokkasho, was launched by musician Ryuichi Sakamoto. Greenpeace has opposed operation of the Rokkasho Reprocessing Plant under a campaign called "Wings of Peace: No more Hiroshima, Nagasaki. Stop Rokkasho", since 2002 and has launched a cyberaction to stop the project.

Rokkasho was a candidate to host the plasma fusion reactor ITER, but lost out to Cadarache, France. Rokkasho has been hosting the Helios high-performance supercomputer centre capable of performing complex plasma physics calculations for fusion research, since January 2012.
