Kojima lived near the sea in Tsujido until he was three, and after returning to the nearby Tokyo area in 1996 he took his eldest son many times to the coastal towns of his memories. On one route in Enoshima they saw fish, ate rice with seafood and manju buns, rode the ESCAR toll escalator—which Kojima called a rip-off—returned by ferry and ended the day in a café: Kojima drank coffee, the boy had juice, and Southern All-Stars songs played in the background.

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.
