Scriptwriter Toyoto Kogisu dies at 69

Toyoto Kogisu, the Japanese scriptwriter whose credits included several episodes of Detective Conan, has died aged 69. The Writers Guild of Japan said he died on September 29, with the organisation's notice published on October 19.

Kogisu's Detective Conan work covered episodes broadcast between 2000 and 2018. Anime News Network highlighted episode 733, “The Wedding Reception and the Two Gunshots”, among his credits. The long-running mystery anime is based on Gosho Aoyama's manga and follows the child detective Conan Edogawa as he investigates crimes while searching for a way to restore his original body.

His writing credits also extended beyond animation. According to Anime News Network, Kogisu worked on live-action series including Taiyō ni Hoero!, Hagure Keiji: Junjōha, Sasurai Keiji Ryojō-hen and Bengoshi Takabayashi Ayuko. The range of those credits places his work across several decades of Japanese television rather than tying his career to one franchise.

The Writers Guild of Japan's announcement was a brief memorial notice confirming Kogisu's death and age. Anime News Network separately reported the details and identified his contribution to Detective Conan. Neither source provided a broader account of his career or the circumstances of his death, so this report sticks to the confirmed information.

Why this matters

Deaths of working writers can be easy to overlook when audiences know the characters and shows more readily than the people who shaped individual episodes. Kogisu's Detective Conan credits are a useful reminder that a long-running anime is built episode by episode, with scriptwriters translating a broader manga world into specific mysteries, conversations and reveals.

The available reports do not suggest a new production announcement or a change to Detective Conan. This is a death notice and a record of Kogisu's contribution, with the Writers Guild's statement serving as the primary confirmation.

Our opinion

The respectful approach here is to keep the focus on the work that can be verified. Kogisu's episode credits give viewers a concrete connection to his career, while the guild notice confirms the essential news without inviting speculation. For fans of Detective Conan, revisiting the credited episodes is a more meaningful tribute than turning a short memorial announcement into an inflated career retrospective.
