Green Legacy Hiroshima was established to safeguard and spread the seeds and saplings of Hiroshima’s A-Bomb survivor trees worldwide. It is hoped that many partners will join this initiative and become active ambassadors in their countries of Hiroshima, its peace message and its green legacy.


The Green Greetings Project was launched by GLH partner and committee member at the Chugoku Shikoku Hakuhodo market design department on August 6, 2005. Over the years the Project has assisted many initiatives surrounding the hibakujumoku, including by designing pro bono the beautiful logos for the trees, and for Green Legacy Hiroshima itself. The excellently designed and intuitive website and mobile app includes interactive maps, tours, and detailed information about the hibakujumoku, with most of the content available in both English and Japanese.
