The area around Rokkasho was known for raising horses during the Kamakura period. During the Edo period, it was controlled by the Nambu 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 municipalities system after the start of the Meiji period, on April 1, 1889, Rokkasho Village was proclaimed from the merger of six small hamlets.


The economy of Rokkasho has traditionally been dependent on agriculture and commercial fishing. From the 1980s onwards, the village has become a center for various energy developments, which now dominate the local economy.[4] Rokkasho's per capita income was $129,676 (1557,8000 Yen $1= 120.13 Yen )[5]

Nuclear industry & ResearchEdit

Nuclear fuel cycle related facilities:

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.[6][7][8][9][10][11][12][13]

In May, 2006, an international awareness campaign about the dangers of the Rokkasho reprocessing plant, Stop Rokkasho,[14] 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",[15] since 2002 and has launched a cyberaction[16] 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 high-performance supercomputer[17] centre capable of performing complex plasma physics calculations for fusion research, since January 2012.[18]
