Distribute and nurture seeds from atomic bomb survivor trees (hibaku tree)

The Secretariat distributes seeds from hibaku trees, which stand in Hiroshima and Nagasaki as silent witnesses, to member cities. Our aim is to raise public peace consciousness through citizens, so we request member cities to plant them in places where many citizens frequent, and to encourage communities to participate in the nurturing of these trees as a symbol of peace.
