IN-DEPTH: NUCLEAR ENERGY IN JAPAN UPDATED JUNE 2016 INTRODUCTION electricity-generating equipment in order to meet electricity demands.3 According to the The March 2011 earthquake, tsunami and the World Nuclear Association, Japan currently resulting partial reactor meltdown at Tokyo relies on imports for approximately 84% of Electric Power Company’s (“TEPCO’s”) its primary energy needs, which, according Fukushima Daiichi Power Station resulted to the finance ministry, cost the country in heightened scrutiny placed on the use approximately ¥24 trillion (roughly $250 of nuclear energy and the safety of nuclear billion) in 2012.4 facilities in Japan. The event was rated by the International Atomic Energy Agency as After halting all nuclear operations in 2012, a Level 7 “major accident,”1 the highest level the Japanese government asked businesses on the International Nuclear and Radiological and households to cut their electricity Event Scale, and generated considerable usage by at least 15% in order avoid possible debate regarding the safety and desirability blackouts. However, meeting energy of nuclear power production. demands during the summer months, when electricity usage peaks, brought increased Given the increased scrutiny placed on the concern that energy needs would not production of nuclear energy in Japan, Glass be met. In response, in June 2012, then- Lewis recommends that shareholders look Prime Minister Yoshihiko Noda delivered a closely at proposals regarding companies’ speech in which he stated that he wanted nuclear operations, as mismanagement of to resume operation of Kansai Electric’s these operations can have significant health, Ohi reactors 3 and 4. According to Noda, policy, safety, environmental, regulatory and “[c]heap and stable electricity is vital.

Japan has the by the halted nuclear power generation. third-highest nuclear capacity by country, Shintani stated that “[l]argely understanding behind the United States and France. Prior the necessity of nuclear power and taking to the 2011 earthquake, Japan relied on into consideration the residents’ opinions as nuclear power for 30% of its electricity, well as the impact on consumers’ livelihoods and had planned to expand that share to and the economy, we decided to agree to 6 nearly 50% by 2030 through the creation a restart.” On June 17, 2012, Noda declared of 14 new nuclear reactors.
