Hideko & OSDI
Dr. Hideko Tamura-Snider founded OSDI in 2007 to educate the public about the consequences of the use of nuclear weapons and plants seeds of peace, hope and reconciliation among people of the world, through educational presentations and cultural exchange programs. To that end she has been interviewed on radio and TV, appeared before professional organizations, university classes, and community groups across the United States and in her native Japan, telling her story and working toward peace and nuclear nonproliferation.

Green Legacy Hiroshima
OSDI has partnered with Green Legacy Hiroshima, a program begun in Japan, under the United Nations, which gathers seeds from trees that survived the atomic bombings at the close of World War II. The seeds have been distributed around the world, to grow and flourish in hundreds of communities. Standing in silence, they remind us that out of tremendous and overwhelming destruction, new life can arise. Along with the Oregon Department of Forestry and Oregon Community Trees, we have placed over 55 Peace Trees throughout Oregon. OSDI also sent 70 more trees other states.
