Japan’s climate policy development has been dominated by a technocratic policy triangle that includes the Ministry of Economy, Trade and Industry; politicians within the dominant Liberal Democratic Party; and industry. This triangle has generated cautious policymaking characterized by gradualism and a focus on the long-term viability of existing industrial assets. However, the acceleration of climate policy under the Suga and Kishida governments of the last two years has been driven by political leadership in response to both competition in East Asia and overtures from the Biden administration. Most crucially, Japan’s stepped-up commitments include a comprehensive vision of economic and energy security that views the current competition over green technology in the Indo-Pacific as crucial for future economic competitiveness. Under the Green Transformation (GX) strategy, industrial policy is back.

  • Energy security and industrial competitiveness are driving the new Japanese approach to climate policy. In the context of a tighter geopolitical environment in the Indo-Pacific area, this approach opens more avenues for cooperation with key allies and partners.
  • The Kishida cabinet is emphasizing several key policy sectors: solar energy, nuclear energy revival, ammonia and hydrogen innovation in combination with continued clean coal use, and electric vehicles.
  • Japan’s climate policy approach will have a strong focus on innovation, competition, and industrial renewal, focusing as much on the supply side as the demand side.
