Kojima distinguished in Hyoryu between passive survival and regaining…

From Hyoryu, Kojima concluded that the human body needs work and movement: the castaway who balances his diet, exposes himself to the sun, and keeps active survives where others fall ill after long periods of immobility. He thought this lesson also applied to modern urban life and that an idle, purposeless existence guided only by desire is not sustainable.

Kojima contrasted The Drifting Classroom with survival stories that end with a return home. His children begin wanting to go back, but accept that they cannot and see themselves as seeds scattered into the future; after Tohoku, Kojima viewed that drifting away from the previous era as a possible new way of living to preserve the future.

Kojima said he continued to pursue dreams and roman —aspirations for heroism, adventure and lofty ideals— even though they are not attainable objects, because the goal keeps a person alive. When he was about to lose them or give up, he would sing the verse about the scarlet scarf from Yamato’s ending song; then he imagined the ship sailing into the black sea of space and regained courage.

Kojima argued that stories about impossible journeys can circulate through culture and help turn them into reality. In response to accusations of escapism, he maintained that fiction contains truth and can serve as a frontline tool to correct real-world problems; for that reason he wants to continue telling stories and creating connections between people, worlds, and times.

Kojima began by identifying with the climber Joji Habu, who selects dangerous, untried routes and turns into reality what no one else has done. However, the cameraman Makoto Fukamachi’s monologue shook him: Kojima recognized that his older self was no longer the pioneering leader but the one who follows behind, returns alive, and goes back to the mountain again and again because it is all he can do.
