Kojima spent thirty-five years wondering what his father had been…

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.

As his eldest son grew, Kojima stopped visiting Kamakura and likewise became too lazy to go back to Kobe; Umimachi Diary reminded him of what he had lost and what he must not forget. At the end of that summer he went to Hayama with his younger son, and from the train saw the sea where he had played with his father and where he had gone with his first son, and he decided to resume that diary of outings when the younger son is old enough.

“I've been stuck with something of a father complex ever since. All the Metal Gear games so far have been paternal stories. They're all about killing your father (laughs).”

As he approached fifty, Kojima acknowledged that studio work was already physically fatiguing and that he should be preparing a successor and retirement, but the person to whom he had handed the baton had died before him. He said he could only pick up Itoh’s last wishes and continue telling stories; he also began the series My Lovable Memes after Itoh’s death to search for new receivers.

“Everyone thinks I do crazy stuff, but I'm sensitive. I lost my father when I was really young. I couldn't really speak to my dad. I had to say: believe in yourself, and do what you believe. That's how I lived and who I am today.”
