The 2018 movie The Miracle of Crybaby Shottan [ja] is based on Segawa's 2006 autobiography of the same name.
The JSA discussed Segawa's petition at its annual general meeting in May 2005, and the membership voted 129 to 52 to grant him a special exception to attempt to become a professional.
Segawa's opponents were to be four professional players (Hiromitsu Kanki, Toshiaki Kubo and Makoto Nakahara and Kunio Yonenaga), one female professional player (Hiroe Nakai), and one apprentice school 3-dan (Amahiko Satō).
His opponent for Game Five was originally scheduled to be Nakahara, but he was replaced by Hideyuki Takano.
Segawa defeated Takano to achieve the necessary third win on November 6, 2005 and was granted professional status by the JSA on the same day.
