Kojima said he loved the work of Teru Miyamoto and had read his novels exhaustively during his adolescence. While seeking escape in fanciful translated books, those novels helped him come to terms with his real, true-to-life self; he placed Kinshu as his favorite, followed by Haru no Yume and Ao ga Chiru.
Kojima continued to consult the annual guide Kono Mystery ga Sugoi not so much to find new books as to check whether the books he had chosen for himself appeared on the list. In 2012 he congratulated himself for recognizing the top entries until he came across Hiroko Minagawa, an author he had not read; this wounded his pride as a daily visitor to bookstores. After learning that Minagawa, now eighty-two, also walked inside a bookstore every day, he delightedly opened The Resurrection Fireplace and immediately proceeded to read two more of her works, Shi no Izumi (Fountain of Death) and Toritsu Suru To no Satsujin (Murder at the Upside-Down Tower).
“I saw the future. If it weren't for Miyamoto-san I wouldn't be where I am.”
Kojima placed his awakening to reading in fifth grade, when he plunged into mystery novels from around the world. He continued with them through sixth grade, and upon finishing elementary school he moved on to science fiction, which he described as his companion until college; from that period he barely remembers reading anything else.
Kojima said he had a particular fondness for true escape and survival stories and recalled rewatching The Great Escape and Papillon in theaters, as well as seeing 127 Hours. He came to Hyoryu because novelist Naoki Hyakuta had read Kojima’s essay on Papillon and recommended Hyoryu and Hagoku (Prison Break).
Kojima discovered Shadow 81 while in his second year of junior high when a faceup stack of the foreign genre novel stood out in Shinchosha’s new-release section; he associated Shinchosha with serious classics and the publisher’s tactfully elegant cover completed the attraction. Thirty-five years later he reread the book and, on a Hayakawa reprint, found his own obi endorsement: he described the novel as his absolute favorite and said he had never seen a plot that surpassed it.
