Keigo Sakamoto, 58, holds Atom, one of the 21 dogs and more than 500 animals he keeps at his home in the exclusion zone near Naraha. Sakamoto, a former caregiver and farmer who refused to leave the exclusion zone, named his dog Atom because it was born just before the 2011 disaster. With donations and support from outside Fukushima, Sakamoto lives with his animals, many of which were abandoned by previous owners as they fled the area
