When Matsuki Kamoshita, 18, moved to Tokyo from Iwaki, Fukushima Prefecture, at the age of 9 right after the triple meltdowns at the Fukushima No. 1 nuclear power plant in March 2011, he endured repeated bullying at his new elementary school.

He was called a "germ.” Some students stabbed his legs with pencils. He was pushed down the stairs. All because he had evacuated from Fukushima in the wake of the nuclear disaster.

Back then, he wrote on a wish list: "I want to go to heaven.”
