At a crematorium in May 2008, a 35-year-old woman and her 38-year-old husband bade farewell to their unborn baby boy, Yuki, whom they dressed in blue clothes and a blue hat.
The baby's bones were so thin and tiny the parents, who declined to be named, were not able to gather the ashes.
"I am sorry that I could not make you into a healthy boy. I am sorry that we had to make this decision when you didn't do anything wrong. It was your mother's fault," the woman wrote in a message to him.
