Ameku M.D.: Doctor Detective

Ameku M.D.: Doctor Detective (Japanese: 天久鷹央シリーズ, Ameku Takao Series) is a Japanese medical-mystery novel franchise written by Mikito Chinen and published by Jitsugyo no Nihon Sha under its Jitsugyo no Nihon Sha Bunko imprint. The series centers on Ameku Takao, a brilliant physician who heads the Comprehensive Diagnostic Department at Ten'i-kai General Hospital, a unit where patients deemed "difficult to diagnose" by other doctors are gathered. Beyond rare and baffling illnesses, Takao also becomes entangled in unexplained deaths and mysteries that even the police cannot resolve, applying her diagnostic genius to uncover the truth behind extraordinary "diseases." The franchise is built around two main book lines: the "推理カルテ" (Reasoning Chart / Deduction Chart) series and the "事件カルテ" (Case Chart) series, with additional spin-off titles such as the "天久翼の読心カルテ" (Ameku Tsubasa's Mind-Reading Chart) line. The official website serves as a hub for the series, listing release schedules, new titles, and related news. In October 2023, a major new project was launched, with Jitsugyo no Nihon Sha Bunko rolling out an intensive seven-month consecutive publication run comprising three completely new works and thirteen "complete edition" reissues, the latter including newly written short stories. The brand has expanded well beyond print. A television anime adaptation of "天久鷹央の推理カルテ" (Ameku Takao's Reasoning Chart) was announced on January 1, 2025, and a live-action television drama adaptation was announced on March 4, 2025, scheduled to begin broadcasting every Tuesday at 9:00 p.m. from April 22, 2025. These adaptations have broadened the franchise's reach into mainstream entertainment. As a commercial property, the Ameku M.D. brand is owned and managed by Jitsugyo no Nihon Sha, Ltd., a Japanese publishing house. The series is authored by Mikito Chinen, a physician-turned-novelist whose medical background informs the franchise's blend of clinical detail and mystery plotting. The brand spans novels, complete editions, junior editions, spin-offs, and multimedia adaptations, with an ongoing publication schedule extending into 2026.

The Ameku M.D.: Doctor Detective franchise is a Japanese medical-mystery novel series written by Mikito Chinen and published by Jitsugyo no Nihon Sha under its Jitsugyo no Nihon Sha Bunko imprint. The series follows Ameku Takao, a genius physician who leads the Comprehensive Diagnostic Department at Ten'i-kai General Hospital, a unit that receives patients other doctors have classified as "difficult to diagnose." The stories combine rare-disease diagnostics with criminal mysteries that even the police cannot solve. The franchise is organized around two principal book lines: the "推理カルテ" (Reasoning Chart) series and the "事件カルテ" (Case Chart) series, supplemented by spin-offs such as "天久翼の読心カルテ" (Ameku Tsubasa's Mind-Reading Chart). The official website functions as the series' information hub, publishing release schedules and news. A major turning point came in October 2023, when a new project was launched: Jitsugyo no Nihon Sha Bunko began an intensive seven-month consecutive publication run, comprising three completely new works and thirteen "complete edition" reissues. The complete editions included newly written short stories. On August 7, 2023, a brand-new Ameku Takao work was released and the seven-month, sixteen-title plan was confirmed. On October 7, 2023, a talk show by author Mikito Chinen was announced for November 7 to mark the release of the latest work and the complete editions. On November 15, 2023, a TSUTAYA-limited connected special story was distributed to commemorate the seven consecutive months of publication. The brand subsequently expanded into multimedia. On January 1, 2025, a television anime adaptation of "天久鷹央の推理カルテ" (Ameku Takao's Reasoning Chart) was announced. On March 4, 2025, a live-action television drama adaptation was announced, set to broadcast every Tuesday at 9:00 p.m. starting April 22, 2025. The publication schedule continued with new titles planned through 2026, including "天久翼の読心カルテⅡ 淡雪の記憶" (June 6, 2025), "鏡面のエリクサー 天久鷹央の事件カルテ" (April 4, 2025), "血脈のナイトメア 天久鷹央の事件カルテ" (December 5, 2025), and "アノマリーの追憶 天久鷹央の推理カルテ" (April 3, 2026).
