A prosecutor's badge is a badge used as identification for prosecutors. It depicts a blazing sun looming over winter frost. It is allegedly designed to portray the severity of the punishment system. Every prosecutor carries a badge, though many don't wear it openly in the way defense attorneys do. Among those who do wear their badges are Chief Prosecutor Bansai Ichiyanagi and his son Yumihiko, as well as the prosecutor in charge of the first UR-1 Incident trial. Manfred von Karma believed in keeping his badge in his pocket at all times and taught Miles Edgeworth, and most other district prosecutors, to do the same.
This badge design was also used by Japanese prosecutors during the Meiji period, albeit on an armband rather than as a lapel pin. Additionally, the design used for the prosecutor's badge can be seen on the floor design of the office of the chief of police.
