Junko Edahiro is one of Japan's top environmental journalists and a major proponent of the country's slow-living movement. She has translated books by Lester Brown, Al Gore, Dennis Meadows, Donella Meadows, David Suzuki and many others into Japanese, and has also written dozens of her own books on climate change, energy, happiness, systems thinking, and many other sustainability topics. A major focus of her work is to promote and facilitate environmental communication and dialogue among governments, corporations and citizens.
Junko also brings prominent opinion leaders to Japan from overseas and organizes networking events for hundreds of business people, policy makers, researchers, and concerned citizens. Through these activities she has become somewhat of an icon of networking across different sectors.
In 2002, along with other collaborators, Junko founded Japan for Sustainability (JFS). Serving as a Chief Executive, since then she has mobilized hundreds of volunteers to research, write, translate and publish thirty news articles every month on a broad range of topics, from regulations, policies, business initiatives, technology development and citizens' local initiatives.
She is also an initiator of the Candle Night campaign in Japan (www.candle-night.org/en/). It has grown to the point that today over five million people participate by turning off their lights on the night of the summer and winter solstices to think about the environment and peace.
From 2002 to 2005 she founded three companies, all related to sustainability. e's, Inc. sells eco-products and supports people aiming for personal transformation. Eco Networks provides translation and consulting services and helps Japanese corporations conduct effective communication on sustainability and corporate social responsibility (CSR). And Change Agent, Inc. provides consulting and education services, using tools such as visioning, systems thinking, communication and management systems.
Junko also speaks on sustainability outside of Japan - in Beijing, Bangdung, London, Stockholm, Berlin, Davos, Washington DC and other cities. She was selected as a council member of International Sustainability Innovation Council of Switzerland in 2008. She also gave a paper at the Fourth Gross National Happiness Conference held in Thimphu, Bhutan in November, 2008. She spoke about new lifestyles and mindsets for a more sustainable society under the title "De-Ownership, De-Materialization, and De-Monetization" at TEDxTokyo in May, 2011.
She was chosen as the most successful career woman in Japan by Nikkei Career Women magazine in 2003. She was selected as one of the "100 Planet Earth Lovers" at the World Expo 2005 in Aichi, Japan. She was named a Prominent Woman Leader in the Environment Movement by the Health and Human Services University of US.
In 2011, Junko founded the Institute for Studies in Happiness, Economy and Society (ISHES) to rethink the relationships among happiness, economy, and society and explore better systems and indicators. ISHES engages in many activities, including seminars and study meetings to develop dialogue skills on these topics.

In 2012, she was appointed as a member of the international experts' working group for the "New Development Paradigm" being promulgated under a royal edict issued by the King of Bhutan. Here she collaborates with others to develop a global network with the world's leading experts and practitioners in sustainability, prosperity, and happiness studies. Others include Lester R. Brown, Denis Meadows, Tim Jackson, and Karma Ura. Through this work, she hopes to contribute to the world's prosperity and happiness with her colleagues by sharing information on the latest research, ideas and insights.
In 2013, to promote the comprehensive study of relationships among happiness, economy, and society, she is holding workshops on the themes of happiness and sustainability. She is creating a new website called "e's Future Co-Creation Forum" to co-create new value by discovering the relationships among factors in a problem. Through this work Junko is contributing to the co-creation of a happy and resilient future through human connections and dialogue.
