Movie
Description
Kogoro Mouri runs the Mouri Detective Agency in Beika Town, a former police officer from the Tokyo Metropolitan Police Department's Division One and arson division. He struggles with investigations when working alone, frequently reaching incorrect conclusions from superficial evidence. Yet, he achieves widespread fame as "Sleeping Kogoro" when cases solve during his apparent unconsciousness, unaware these solutions stem from Conan Edogawa's covert actions using sedatives and voice-changing technology to deliver deductions through him.

A long-term separation defines his relationship with his lawyer wife, Eri Kisaki, despite mutual unresolved feelings. He raises their daughter, Ran Mouri, as a single parent. Kogoro exhibits habits including heavy smoking, frequent drinking, gambling on horse races and mahjong, and open admiration for attractive women, especially idol Yoko Okino – whose memorabilia fill his office and home. These traits fuel his marital issues and often embarrass Ran.

Despite his investigative shortcomings, Kogoro possesses exceptional physical abilities honed as a judo team ace at Beika University and demonstrates skilled marksmanship. His focus and deductive reasoning notably sharpen when cases involve personal connections, such as threats to Ran or Eri, revealing competence in logic and understanding human dynamics. He holds a strong sense of justice, opposing murder unconditionally and intervening to prevent suicides or further violence by perpetrators.

In "The Fist of Blue Sapphire," a lottery-funded family vacation takes Kogoro to Singapore. Initially reluctant to work during leisure, he accepts an investigation into the theft of the "Fist of Blue Sapphire" jewel after persuasion by Shinichi Kudo (actually Kaito Kid in disguise), who highlights potential professional benefits from befriending a reserve police officer. He participates in the investigation at Leon Lowe's vault but does not play a central role in solving the overarching mystery or heist.

His background includes attending Teitan High School and Beika University alongside Eri, Yukiko Fujimine, and actress Ruri Ujo. He has medical issues like high cholesterol and uric acid. Kogoro occasionally solves cases unaided, typically when emotionally invested in scenarios mirroring his family life or involving past acquaintances.
