Green Legacy Hiroshima (GLH) Initiative

The GLH Initiative is a global volunteer campaign, aiming to disseminate the universal message of trees that survived the atomic bombing of Hiroshima. Created in 2011 by two friends, Nassrine Azimi and Tomoko Watanabe, GLH shares worldwide the double message of caution and hope that the unique survivor trees of Hiroshima (and ultimately Nagasaki) represent, recalling on the one hand the dangers of arms of mass destruction and nuclear weapons in particular, and on the other hand the sacred character of mankind and the resilience of nature. Currently, seeds and saplings from the A-bombed trees are growing in 40 countries - in a sustained, long-term (1000-year) campaign, joining other efforts for a nuclear-free and more ecological planet.


Green Legacy Hiroshima Committee, International Scientific Advisors, Secretariat and Regional Hubs

The GLH Committee was set up to help the initiative in its day-to-day operations and to be a bridge with the Working Group members and other partners, who are only able to meet a few times a year. The Committee members represent a diverse group of individuals and backgrounds, all united by their love of the hibakujumoku.

Hiroshima Hibaku-Jumoku Working Group

Green Legacy Hiroshima is part of a Working Group that also includes Hiroshima City, Mayors for Peace, The Hiroshima Botanical Garden, Hiroshima Prefecture and Hiroshima University, in addition to ANT and UNITAR. The Working Group is informal, and functions as both a coordinating and information sharing body. It meets once or twice a year (before the COVID-19 pandemic) and is hosted in rotation by ANT-Hiroshima, the UNITAR Hiroshima Office, and Mayors for Peace. A few times a year, under the guidance of GLH Master-Gardener Chikara Horiguchi and with the help of The Hiroshima Botanical Garden, members of the Working Group also come together for seed-picking of selected Hibaku-Jumoku.


GLH is fortunate to be working with a network of partners around the world passionate about nature, peace, and disarmament. As a small non-profit, volunteer initiative, however, GLH has very limited capacity and therefore sends seeds of Hiroshima's Hibaku-Jumoku only to institutional (not individual) partners, such as universities, botanical gardens, etc that can commit to the long-term care of the trees.

If your institution is eligible please contact GLH Co-Founder and Coordinator: Nassrine Azimi (greenlegacy@unitar.org). Please note that due to a large volume of requests, we cannot respond to requests from individuals. We thank you for your understanding.
