On August 6, 1945, at a quarter-past 8 a.m., bonsai master Masaru Yamaki was inside his home when glass fragments hurtled past him, cutting his skin, after a strong force blew out the windows of the house. The U.S. B-29 bomber called the “Enola Gay” had just dropped the world’s first atomic bomb over the city of Hiroshima, at a site just two miles from the Yamaki home. The bomb wiped out 90 percent of the city, killing 80,000 Japanese immediately and eventually contributing to the death of at least 100,000 more. But besides some minor glass-related injuries, Yamaki and his family survived the blast, as did their prized bonsai trees, which were protected by a tall wall surrounding the outdoor nursery.
