Heiji is an undercover policeman in the city of Edo. He possesses a superior skill of throwing coins. When a criminal is caught, Heiji throws coins at the offender and reveals his true identity.

Like “Abarenbo Shogun,” “Mito Komon” and “Toyama no Kinsan,” “Zenigata Heiji” is about an official working undercover to catch criminals. The hero was created by novelist Kodō Nomura in 1931.
