Three basic features of the nation's system of criminal justice characterize its operations. First, the institutions--police, government prosecutor's offices, courts, and correctional organs-- maintain close and cooperative relations with each other, consulting frequently on how best to accomplish the shared goals of limiting and controlling crime. Second, citizens are encouraged to assist in maintaining public order, and they participate extensively in crime prevention campaigns, apprehension of suspects, and offender rehabilitation programs. Finally, officials who administer criminal justice are allowed considerable discretion in dealing with offenders.
Until the Meiji Restoration in 1868, the criminal justice system was controlled mainly by daimyo (see Rule of Shogun and Daimyo , ch. 1). Public officials, not laws, guided and constrained people to conform to moral norms. In accordance with the Confucian ideal, officials were to serve as models of behavior; the people, who lacked rights and had only obligations, were expected to obey. Such laws as did exist were transmitted through local military officials in the form of local domain laws. Specific enforcement varied from domain to domain, and no formal penal codes existed. Justice was generally harsh, and severity depended upon one's status. Kin and neighbors could share blame for an offender's guilt: whole families and villages could be flogged or put to death for one member's transgression.
After 1868 the justice system underwent rapid transformation. The first publicly promulgated legal codes, the Penal Code of 1880 and the Code of Criminal Instruction of 1880, were based on French models. Offenses were specified, and set punishments were established for particular crimes. Both codes were innovative in that they treated all citizens as equals, provided for centralized administration of criminal justice, and prohibited punishment by ex post facto law. Guilt was held to be personal; collective guilt and guilt by association were abolished. Offenses against the emperor were spelled out for the first time.
Innovative aspects of the codes notwithstanding, certain provisions reflected traditional attitudes toward authority. The prosecutor represented the state and sat with the judge on a raised platform--his position above the defendant and the defense counsel suggesting their relative status. Under a semi-inquisitorial system, primary responsibility for questioning witnesses lay with the judge and defense counsel could question witnesses only through the judge. Cases were referred to trial only after a judge presided over a preliminary fact-finding investigation in which the suspect was not permitted counsel. Because in all trials available evidence had already convinced the court in a preliminary procedure, the defendant's legal presumption of innocence at trial was undermined, and the legal recourse open to his counsel was further weakened.
The Penal Code was substantially revised in 1907 to reflect the growing influence of German law in Japan, and the French practice of classifying offenses into three types was eliminated. More important, where the old code had allowed very limited judicial discretion, the new one permitted the judge to apply a wide range of subjective factors in sentencing.
After World War II, occupation authorities initiated reform of the constitution and laws in general. Except for omitting offenses relating to war, the imperial family, and adultery, the 1947 Penal Code remained virtually identical to the 1907 version. The criminal procedure code, however, was substantially revised to incorporate rules guaranteeing the rights of the accused. The system became almost completely accusatorial, and the judge, although still able to question witnesses, decided a case on evidence presented by both sides. The preliminary investigative procedure was suppressed. The prosecutor and defense counsel sat on equal levels, below the judge. Laws on indemnification of the wrongly accused and laws concerning juveniles, prisons, probation, and minor offenses were also passed in the postwar years to supplement criminal justice administration.
