ClientEarth is a group of international legal experts on climate, energy and the environment. We use the law in partnership with governments, the private sector and the public to address climate change, capture the opportunities of the low carbon transition and protect nature.


We have built a global team of corporate and financial law experts specialising in climate risk and decarbonisation across eight offices in Europe, China and the United States – providing the legal framework and tools for the private sector to lead on climate action. We are helping to strengthen corporate climate governance and embed climate change in investment, regulatory and policy decisions around the world.

Our new Tokyo office is looking for a lawyer qualified in Japan (bengoshi).

This is a unique opportunity for an energy, environmental, corporate, financial and / or litigation lawyer with interest in energy and / or environmental law, policy and regulation to support decarbonisation and protection of the environment. The ideal candidate will have good English and experience from a top-tier law-firm/in-house department and/or government. There is no requirement for this position to have specific exposure to environmental law or have worked in the not-for-profit sector.

You will work closely with an expanding team in our new Tokyo office as well as colleagues located in London, Brussels, Beijing and Southeast Asia.

ClientEarth in Japan will be firmly embedded within Japan’s social, political, economic and cultural context and will use the law to support accelerated government and private sector leadership on climate change. The Tokyo office is bringing together Japanese qualified lawyers (bengoshi) with specialised backgrounds in corporate, financial, litigation, energy and / or environmental, as well as other professionals with backgrounds in climate change and communications.

  • Research and analysis of corporate and financial law and regulation requiring disclosure and management of climate-related financial risks and opportunities in Japan
  • Work closely with the corporate and financial sectors and external stakeholders such as corporates, investors, government, think tanks, and civil society organisations to accelerate Japan’s transition to a net zero economy and strengthen Japan’s climate and environmental policy.
  • Identifying opportunities and developing strategies for using energy, environmental, corporate and financial law and regulation to drive climate ambition and action and accelerate the net zero transition in Japan and across Asia
  • Contributing consistently and meaningfully to team’s monitoring, evaluation and learning activities to support a culture of continuous learning and innovation within ClientEarth.
