Background

Plans for the Kaminoseki nuclear power plant were first introduced by Chugoku Electric in 1982. Local opposition from community members of Iwaishima, a small island a few kilometers away from the planned site, delayed the project by adopting a resolution in 1983 to oppose the proposed plant. Sixteen years later, Chugoku Electric submitted an environmental assessment report to the Agency of Natural Resources and Energy. A year later, in 2000, the agency requested an additional assessment. The planned site lies on the Shidai Sho-hachimangu Shrine, whose land sale was opposed by the former chief priest. In 2003, the Association of Shinto Shrines dismissed the priest, which enabled Chogoku Electric to buy the land. In 2008, the operator obtained a public water reclamation permit and submitted a permit to build one of the reactors. In 2010, the Nuclear and Industrial Safety agency requested an additional geological survey. Between 2009 and 2011, prior to the Fukushima nuclear accident, the company's site reclamation and survey work faced strong resistance.

All site works at Kaminoseki were halted after the Fukushima accident. In October 2012, Chugoku requested an extension of the public water reclamation permit approved four years prior. The Yamaguchi prefectural government approved this request in August 2016, extending the company's ability to reclaim the site until July 2019. Chugoku Electric applied for postponement of this expiry, which was approved and changed the proposed construction start date from July 2019 to January 2023. As of April 2024, the nuclear plant's construction is suspended. Chugoku Electric is now conducting drilling surveys at the planned site of the Kaminoseki nuclear power plant for the possible construction of an interim storage facility for spent nuclear fuel.
