The implementation of legal enforcement constitutes a pivotal instrument within the criminal justice apparatus, serving as a crucial element in the broader strategy to combat corruption. The criminalization of corruption and the establishment of accountability for such actions can be achieved through legislation. This can be achieved in a number of ways, including the control of power delegated from the upper level and/or the promotion of political transparency. An analysis of judicial behaviour in a comparative law context must encompass not only formal social control by law but also informal social control, particularly within the context of historical, sociopolitical, sociolegal and cultural factors. Throughout the annals of Japanese legal history, the most prominent legal norm is dōri as the fuzzy, unwritten, conceptual and divine principle. The concept was implemented in a manner analogous to equity in common law jurisprudence.
