Japan will shift further toward renewable energy and cut dependence on fossil fuels and nuclear power, according to the country's energy plan approved Tuesday by the Cabinet.

Ahead of the automatic July renewal of the U.S.-Japan agreement on the peaceful use of nuclear energy, the plan for a medium- to long-term energy policy also mentioned that Japan will work to reduce its plutonium stockpile for the first time.

The increased focus on renewables under the 2015 Paris climate accord underscores the nation's daunting challenge to reduce greenhouse gas emissions drastically in the years ahead.
