What to do about the future of Japan’s energy supply, especially when it comes to nuclear power and renewables, has sparked an intense debate between the four candidates for the Liberal Democratic Party presidency, with each laying out their energy strategies for a green society.

Among them, Sanae Takaichi is the most pro-nuclear energy candidate, while the other three — Fumio Kishida, Taro Kono and Seiko Noda — say that it's more or less inevitable that Japan will have to rely on nuclear power for the time being.

Last October, Prime Minister Yoshihide Suga committed Japan to becoming a carbon neutral society by 2050. To achieve this goal, the government announced in April that it is targeting a 46% reduction in greenhouse gases by 2030, based on 2013 levels.
