Robin Takashi Lewis | ルイスロビン敬

Hello! Thanks for stopping by my website 🙂 I’m half British and half Japanese, based in Tokyo.

I am the co-founder of MyMizu, an award-winning social enterprise reducing consumption of single-use plastic bottles by connecting people with 200,000 free water refill spots around the world.

I also work as a Consultant at the World Bank’s Global Facility for Disaster Reduction and Recovery (part of the Climate Change Group) and run an organisation called Social Innovation Japan – a platform for action focusing on the 17 UN Sustainable Development Goals (SDGs).

I’m a professional speaker (TEDx, 50+ universities & international conferences), facilitator (high-level UN meetings), trainer (certified Monitoring & Evaluation trainer), and media commentator (featured by CNN, The Guardian, selected as Top 100 Influencer for the SDGs).

I also serve as an advisor for purpose-driven programs (e.g. Judge for the world’s largest student social entrepreneurship competition, the Hult Prize), and have been selected as a Japan Foundation Fellow, an Asia-Europe Foundation Young Leader, a One Young World Ambassador, and an UNLEASH Innovation Lab SDG Talent.

I have a blend of both on-the-ground experience – leading humanitarian operations and training programs over 5+ years in countries such as Haiti, Nepal, Vanuatu and Mozambique – as well as policy-related experience including co-authoring government reports and organising programs at international conferences.

In my free time, I write and take photos… In 2017, I started a storytelling project which involved walking solo for 600+km along Japan’s tsunami-affected coastline to document the region’s recovery 7 years since the 2011 Great East Japan Earthquake and Fukushima nuclear disaster (the “Explore Tohoku” project).

If you’re interested, you can read some of my stories and posts on my Medium page.


As a trainer and facilitator, I’ve delivered workshops and seminars in countries including Japan, Hong Kong, Mexico, and France (COP 21). I also speak regularly at schools, universities, and conferences (e.g. TEDx, University of Tokyo, Sonora Climate Change Summit in Mexico, and USJC Annual Conference in San Francisco), and serve as a mentor and advisor for purpose-driven programs around the world.
