A decade ago, Sakae Kato stayed behind to rescue cats abandoned by neighbours who fled the radiation clouds belching from the nearby Fukushima nuclear plant. He won’t leave. “I want to make sure I am here to take care of the last one,” he said from his home in the contaminated quarantine zone, adding: “After that, I want to die, whether that be a day or hour later.” So far he has buried 23 cats in his garden. He is looking after 41 others in his home and another empty building on his property.
