One day when Saburo Kita was 14, he was taken from an institution for troubled children to see a doctor. Despite protesting that his health was fine, he was ordered to strip, lie down on a table, and was given a local anaesthetic.

Then the surgery began.

He was left with a thick, v-shaped scar on his lower body and questions about what had happened. Months later, talking with a friend, he learned that he had been sterilized. So had two others from the same institution in Miyagi Prefecture.
