After public sentiment turned sour on nuclear power following a nuclear disaster in March 2011 triggered by a massive earthquake and tsunami, the government repeatedly said it was not considering building new nuclear reactors or replacing existing ones. But the war in Ukraine has driven energy prices sharply higher and threatened stable energy supplies for Japan, a resource-scarce country that relies heavily on fossil fuel imports, prompting officials to look into greater use of nuclear power. The government aims to submit the relevant bills to implement the new policy to an ordinary parliamentary session that will convene early next year, Prime Minister Fumio Kishida said at a meeting focused on achieving the country's green transformation. Green transformation is an initiative to transform the economy based on fossil fuels into one centered on cleaner energy, such as solar and wind power.
