Kojima regarded the primary family form as a unit of four: his parents, his brother two years older, and himself. After moving from Tokyo toward Kansai, his parents built a house in 1970 in a new development in Hyogo, distant from grandparents and other relatives; Kojima’s father presented that house as where they were starting and from which their children could also begin. They did not have the typical suburban dog because Kojima’s mother had asthma.

“I felt lonely when I was talking to my friends because they couldn't understand. I wanted to go home … and turn on the lights because I was frightened. I had so many friends at school, but was lonely. I didn't tell anyone. I thought I was sick.”

“It became a habit which I still have. ... I'd think up stories because I had so much time alone.”

Kojima recalled that when his son was small they did all kinds of activities and trips together, but that abruptly ended when his son started junior high and preferred to be with his friends. Since Kojima's own father died when he was thirteen and he had no experience of going through adolescence with a father, he said he did not know what closeness or distance to adopt with his son; he sought guidance by rereading Early Autumn.

Kojima said loneliness had accompanied him since childhood and reached its worst during his adolescence, even when he was surrounded by family, friends, school and activities. He described how a switch could flip in the middle of having fun, making the feeling stronger the more numerous the crowd was; at the end of the year, when the city was liveliest, he spent sleepless nights fearing that the loneliness might one day kill him.
