Detective Chief Inspector James Harold Japp, originally also known as Inspector Japp, is one of the two triangonists (alongside Fecility Lemon) in Agatha Christie's Hercule Poirot series. He is a Detective Chief Inspector (formerly an Inspector before his promotion) from the Scotland Yard and a friend, ally, and sometimes a rival of Poirot.

He is a major protagonist in The Mysterious Affair at Styles (1920), The Big Four (1927), Peril at End House (1932) and Lord Edgware Dies (1933), the deutergaonist in Death in the Clouds (1935), a major protagonist in The A.B.C. Murders (1936), and the deutergaonist in One, Two, Buckle My Shoe (1940).

He has been portrayed by various actors including Melville Cooper, John Turnbull, Maurice Denham, David Suchet, Philip Jackson and Kevin McNally.

Overview

Inspector is the most recurring police character in the series and served as major protagonist, triangonist and sometimes even as deuteragonist in several stories. He is partially inspired by Inspector Lestrade in Sherlock Holmes, but with much more involvement to the story. Even so, comparing to his much later replacement, Superintendent Spence, Japp still shows shadows of stereotypical police character in a detective novel series. He most notably serves as the major protagonist in seven Poirot novels.

However, in the original stories, Japp no longer made any appearance after 1940, as One, Two, Buckle My Shoe became his final appearance. Unlike Captain Arthur Hastings, who made his last apperance in Curtain, Japp never appeared in a later installment of the series post-1930s. It is unknown what happened to him afterwards.

Personality

James Japp, while being a competent detective, is no match for Poirot; he frequently finds himself a step behind the great detective but has developed a grudging respect for the man's abilities over their years together. Japp and Hastings often commiserate on their confusion and inability to keep up with Poirot on cases. At times, Japp cannily plays upon Poirot's ego in order to nudge the detective into taking up cases, but in such ways as Poirot does not seem to realize that Japp is manoeuvring him.

Japp and Hastings are also generally astonished to find that Poirot cannot understand anything typically English (like cricket, which he maintains is utter nonsense).

Japp has been depicted in several novels and short stories, all featuring Hercule Poirot:

In other appearance

Agatha Christie's Poirot

In Agatha Christie's Poirot, like Miss Lemon, Japp has much more importance and role particularly in the first eight series, since he also appeared in several stories that he hardly ever appeared and became much more supportive. Here, his extra roles includes; as a major protagonist in Hickory Dickory Dock and several adaptations short stories like The Chocolate Box (replacing Hastings), and as the deuteragonist of Hercule Poirot's Christmas (replacing Colonel Johnson from the novel).

Ever since the 2001 adaptation of Evil Under the Sun, neither Hastings, Miss Lemon nor Japp had ever made an apperance for the next 12 years, and several police characters were written to replace him. Nevertheless, with the exception of Superintendent Spence (who was originated from the novel), most of the police replacement are not well-received.

After 12 years and four series of absence, Japp made his final apperance in the series within the 2013 adpatation of The Big Four. Here, Japp served as the deuteragonist instead of Hastings, who became a rather minor character that only appeared in Poirot's (false) funeral and the ending.

The ABC Murders (2018 miniseries)

In the 2018 BBC miniseries adaptation of The ABC Murders, the series starts with a retired Japp dying of a heart attack, and a recurring sub-plot is Inspector Crome, Japp's protege, expressing distrust of Poirot as he feels that working with Poirot ruined Japp's career.

Trivia

  • In the 1985 film Thirteen at the Dinner (based on Lord Edgware Dies), he was portrayed by David Suchet, who would later portray Hercule Poirot himself in Agatha Christie's Poirot and the 2006 video game adaptation of Murder on the Oriend Express.
  • In both Agatha Christie's Poirot and the BBC 4 Radio adaptations, he was portrayed by Philip Jackson.
  • Among all of the recurring characters, Japp appeared in seven novels, only losing to Hastings who appeared in eight novels.
