In Yokoku Satsujin, the 2019 TV Asahi Japanese adaptation of A Murder is Announced, Onigawara Banroku (鬼瓦胖六 - Banroku Onigawara in Western format) is a Chief Inspector (警部, Keibu) from Shibuya East police. Nicknamed "Oniban", he takes charge of the investigation into the death of Kurumai Kyuzo because shooting victim lived in his area of jurisdiction. Oniban's large team of detectives handle most of the police procedural aspects of the investigation such as searching for clues at the crime scene, performing background checks into the suspects and so on. In the course of the investigation, Oniban works with Shokokuji Ryuya and his subordinates from "s1s" (First Criminal Investigation Division, Tokyo Metropolitan Police Department). The relationship is analogous to the local police working with the C.I.D. of Scotland Yard.
There is no direct parallel to Oniban in the original novel unless one counts Dermot Craddock from Middleshire County Police.
Oniban is portrated by Murata Yuhiro (村田雄浩).
