Having little contact with large real-life families, Kojima looked…

In 2001 Kojima went on a whim with his young son to see Crayon Shin-Chan: The Fierceness That Invites the Storm! The Adult Empire Strikes Back and became hooked on the Nohara family from Shin Chan, whose ability to band together in a crisis struck him as a new model of Japanese family. After the birth of his second son his own family grew from three to four, but he admitted he was still not the ideal father: he might have reached the level of the workaholic Hiroshi, while Charles Ingalls remained beyond his reach; he wanted his children to be inspired by their real-life family rather than by television idols.

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.

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.

Comparing his fathering to Early Autumn, Kojima admitted he could not teach his children carpentry, boxing, and cooking like Spenser. He drew from the novel that one can only teach the things one knows how to do, the world one has seen, and one’s own way of living; yet he believed that the exchange of teaching and learning broadens the future and that conveying confidence can connect children with their destiny.

Kojima described his father as a chemist involved in the development of new medicines who, within the corporate structure, was nevertheless a salaryman enduring crowded trains, conflicts with coworkers and persistent fatigue while continuing to work, and who finally managed to buy a house in a Kansai suburb. In that newly created town with no shared past, families and children measured one another by academic background and job title as if playing a card game; Kojima rebelled by choosing the then-young video game industry, where he believed titles weren’t necessary and only a person’s ability mattered.
