Hello! I’m half British and half Japanese, based in Tokyo. I’m the Co-founder of mymizu, an award-winning initiative reducing consumption of single-use plastic bottles by connecting people with 200,000 free water refill spots around the world.

I also run Social Innovation Japan – a platform for action focusing on the 17 UN Sustainable Development Goals (SDGs).

I’m a professional speaker (TEDx, 100+ universities, conferences and events), facilitator (high-level UN meetings), trainer (certified Monitoring & Evaluation trainer), and media commentator (CNN, Guardian and others).

In 2017, I walked 600+km solo along Japan’s tsunami-affected coastline to document the region’s recovery 7 years since the 2011 Earthquake and Fukushima nuclear disaster, and support the recovery of the tourism industry through this free online guide.

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

Since 2011, I’ve been extremely fortunate to be able to deliver workshops and seminars in Japan and all over the world. I’m also invited to speak regularly at schools, universities and conferences on themes such as sustainability, SDGs & social innovation.
