Kazuhiko Torishima

He is a member of the Tokyo Organising Committee of the Olympic and Paralympic Games' Mascot Selection Panel, who determined the process for choosing the mascots of the 2020 Summer Olympics. The panel decided to allow children a hand in the selection of the mascot for the first time at an Olympic Games. Torishima said, "Kids' minds work differently from adults'. As a member of the panel, I like to think my job is to help bridge that gap."

In 2016, Torishima claimed that when he became a deputy editor at Weekly Shōnen Jump he created teaching materials for how the editors should help their manga artists that are still used to this day.

Torishima retired from Shueisha in August 2015 and became president of Hakusensha in November 2015. His term as president was set for two and a half years. In November 2018, Torishima was promoted to Representative Director.

He became a member of the board of directors at Shueisha and was appointed full-time Director of Business in August 2004. He served during the establishment of Shogakukan-Shueisha Productions in 2008. Torishima became a managing director (CEO) at Shueisha in August 2009 and promoted to Senior Managing Director in August 2010. In December 2010, he spoke at the New Manga Creators Awards in response to the Tokyo Metropolitan Ordinance Regarding the Healthy Development of Youths's controversial passing of the industry opposed Bill 156. There he challenged new manga artists to "produce manga that would blow away [Tokyo Governor] Shintaro Ishihara."

Torishima was editor-in-chief of the video game-themed V Jump when it launched in 1993. In February 1996, he took over as editor-in-chief of Weekly Shōnen Jump during declining sales. While circulation continued to decline, blockbuster series such as One Piece and Naruto were launched. He was the magazine's editor-in-chief until June 2001.

Torishima joined Shueisha in 1976, the year he graduated from Keio University, wanting to work on Monthly Playboy because of their high-quality short stories. However, he was assigned as an editor at Weekly Shōnen Jump, despite having never really had any contact with manga until Shueisha sent him their products for reference, and put in charge of Doberman Deka. After this series jumped from around thirteenth in the reader rankings to third and going to the Shogakukan archives to study classic manga, Torishima finally became interested in his job. Preferring shōjo manga such as Kaze to Ki no Uta and Poe no Ichizoku, he felt that Jump manga at the time "had no intelligence or depth" and decided to help foster manga he found interesting as long as they ranked high with readers. He also studied the first chapter of Ore wa Teppei panel by panel and the layout and angles in each one, because he felt it was the easiest manga to read and tried to impart this basic structure to his artists. Torishima was most notably editor to Akira Toriyama during Dr. Slump (1980) and the beginning of Dragon Ball (1984), and to Masakazu Katsura during Wingman (1983).
