Confessions The Constitution and the
Criminal Code include safeguards to ensure that no criminal suspect can be compelled to make a self-incriminating conviction. In 2003, the use of leather restraining body belts was abolished. Softer leather handcuffs without body belts were instituted as substitute restraining devices. Amnesty International has urged Japan to reform its police interrogation methods.
Deaths of prisoners There have been accounts of prisoners in Japan that have died under suspicious circumstances
while in custody. • On June 20, 1994, Iranian national Arjang Mehrpooran died from unknown causes while in custody for a visa violation at the Minami Senju police station. Allegations have been made that his death was caused by assault. • On August 9, 1997, Mousavi Abarbe Kouh Mir Hossein, an Iranian national, had his neck broken and died while in the custody of the Kita Ward Immigration Detention Center. • In 2001, two
Nagoya prison guards reportedly sprayed a high-power water
hose at an "unruly" inmate's anus, resulting in his death the following day. In the outcome of his March 2003 trial, the warden was warned to prevent further abuses by his subordinates. • In 2002, an inmate at
Nagoya Prison died after guards, as a disciplinary measure, used leather handcuffs and body belts too tightly clinched. • On March 22, 2010, Abubaka Awudu Suraj, a citizen of
Ghana, died while in the custody of the Japanese Immigration Bureau while being deported from Japan. • On March 6, 2021,
Wishma Sandamali, a Sri Lankan woman, died in custody at an immigration detention facility in Nagoya after her requests for provisional release and adequate medical care were denied. In 2003, the Justice Ministry formed a special team to investigate 1,566 prisoner deaths from 1993 to 2002. A preliminary report suggested that nearly one third of the cases involved suspicious circumstances. However, in June, the Ministry announced that there was evidence of abuse only in the two Nagoya fatalities. Regarding the other suspicious deaths, the Ministry said that approximately 10 deaths could be attributed to poor medical care. The authorities reported they had lost the documentation on nine deaths in Tokyo's
Fuchū Prison. The remaining deaths were determined to be "not suspicious". As of May 2019, Japan has not signed nor ratified the
Optional Protocol to the Convention against Torture and other Cruel, Inhuman or Degrading Treatment or Punishment.
Prison system In recent years, overcrowding in Japanese prisons has decreased after a long period in which facilities operated at more than 100% of their intended capacity. According to official data from 2024, overall prison density declined to about 56.6%, following a reduction in the number of incarcerated individuals, which reached 40,881. With this decline, Japan is now among the countries with the lowest incarceration rates globally, at approximately 33 prisoners per 100,000 inhabitants. The decrease in inmate populations has also reduced the practice of housing more than one prisoner in cells designed for single occupancy. Prison conditions met international standards; although some lacked adequate medical care and sufficient heating in the winter or cooling in the summer and some facilities were overcrowded. Prisoners were not allowed to purchase or receive supplementary food. While death records are kept for 10 years, many of them were missing, which sparked an ongoing review of the prison system. Prisons operated at an average 117% capacity. In some institutions, two inmates were placed in cells designed for one inmate, and thirty or sixty in cells meant for 15. According to prison officials at
Fuchū and
Yokohama prisons, medical attention was inadequate. The MOJ's Corrections Bureau likewise acknowledged that correctional facilities lacked medical preparedness. The Government's Project Team on Medical Issues of Correctional Institutions continued to consult with related organizations on such issues as increasing medical staff, upgrading medical conditions during nights and weekends, and strengthening cooperative relationships with medical institutions in the community. In May, the Minister formed a subcommittee to improve prison medical facilities. In some institutions clothing and blankets were insufficient to protect inmates against cold weather. Most prisons did not provide heating during nighttime hours in winter despite freezing temperatures, subjecting inmates to a range of preventable cold injuries. Foreign prisoners in the Tokyo area continued to present to visiting diplomats during the year fingers and toes affected by
chillblains of varying severity, the direct result of long-term exposure to cold. According to the
Japan Federation of Bar Associations, the authorities are permitted to read letters sent or received by prisoners and they are not required to disclose this practice to prisoners. If the content is deemed "inappropriate", the letter may be
censored or confiscated. All visits with convicted prisoners were monitored; however, prisoners whose cases were pending were allowed private access to their legal representatives. The MOJ is not required to inform a condemned inmate's family prior to the person's execution. Human rights organizations reported that lawyers also were not told of an execution until after the fact and that death row prisoners were held for years in solitary confinement with little contact with anyone but prison guards. Parole may not be granted for any reason, including medical and humanitarian reasons, until an inmate has served two thirds of his or her sentence. The JFBA and human rights groups have criticized the prison system, with its emphasis on strict discipline and obedience to numerous rules. Prison rules remained confidential. While the
Prison Law Enforcement Regulation stipulates that the maximum time prisoners may be held in single cells is 6 months, activists claim that wardens continued to have broad leeway in enforcing punishments selectively, including "minor solitary confinement", which may be imposed for a minimum of 1 and not more than 60 days. Claims have also been made that prisoners were sometimes forced to kneel motionless in an empty cell for several hours at a time; however, foreigners and the handicapped were allowed to sit on a hard stool, at the discretion of the prison warden. In December, the
Upper House passed both a
Crime-Victims law and a revision to the 1908
Prison Law. The Crime-Victims law calls for compensation and counseling for crime victims, upholding victims' rights, and providing victims with criminal investigation information. Aimed at toughening penalties against felons, the Penal Code revision establishes new charges for gang rape, increases maximum prison terms and penalties for life-threatening crimes, and extends the statute of limitations for prosecuting capital offenses from 15 to 29 years. In February 2003, the government ratified the
Convention on the Transfer of Sentenced Persons, allowing foreign prisoners to petition to serve their sentences in their home country. The government added the stipulation that prisoners must serve at least one third of their sentence in Japan before petitions will be considered. As of June 2007, 10 American prisoners have been transferred to the
United States to complete their sentences. Women and juveniles were housed separately from men; however, male prison guards sometimes guarded female prisoners. During the year, a male prison warden was charged with "violence and cruelty by a special public officer" for engaging in sexual acts with a female inmate awaiting trial. During the year, some women's detention facilities were operating over stated capacity. Pretrial detainees were held separately from convicted prisoners. While the government limited access by human rights groups to detention facilities, prison visits were allowed. However,
Amnesty International claimed that human rights groups were not allowed access to Nagoya prison because of ongoing court cases related to alleged abuses.
Prohibition of arbitrary arrest or detention The Constitution prohibits
arbitrary arrest and detention, and the Government generally observes these prohibitions. The law provides for judicial determination of the legality of detention. Persons may not be detained without charge, and prosecuting authorities must be prepared to demonstrate that probable cause exists to detain the accused. Under the law, a suspect may be held in detention at either a regular detention facility or "substitute" (police) detention facility for up to 72 hours. A judge must interview suspects prior to detention. A judge may extend preindictment custody by up to two consecutive 10-day periods based on a prosecutor's application. These extensions were sought and granted routinely. Under extraordinary circumstances, prosecutors may seek an additional 5-day extension, bringing the maximum period of preindictment custody to 28 days. The
National Police Safety Commission oversees the
National Police Agency (NPA). In addition, each prefecture has a prefectural police safety commission as well as a prefectural police agency, which was primarily funded by the prefecture's budget. Corruption and impunity were not problems within either the national or the prefectural police forces. Under the
Criminal Procedure Code, police and prosecutors have the power to control or limit access by legal counsel when deemed necessary for the sake of an investigation. Counsel may not be present during interrogations at any time before or after indictment. As a court-appointed attorney is not approved until after indictment, suspects must rely on their own resources to hire an attorney before indictment, although local bar associations provided detainees with limited free counseling. Critics charged that access to counsel was limited both in duration and frequency; however, the Government denied that this was the case. Incommunicado detention could be used for up to 23 days. Critics charged that allowing suspects to be detained by the same authorities who interrogated them heightened the potential for abuse and coercion. The Government countered that cases of persons sent to police detention facilities tended to be those in which the facts were not in dispute. An MOJ regulation permits officials to limit the amount of documentation related to ongoing court cases retained by prisoners. The
Law for Expediting Court Procedure became effective in 2003. The average trial period in 2005 was 3.2 months for criminal cases and 8.2 months for civil cases. The length of time before a suspect was brought to trial depended on the nature of the crime, but rarely exceeded 3 months from the date of arrest; the average was 1 to 2 months.
Trials The Constitution provides for an independent judiciary, and the Government has generally respected this provision in practice. The Cabinet appoints judges for 10-year terms, which can be renewed until judges reach the age of 65. Justices of the
Supreme Court can serve until the age of 70, but face periodic review through popular referendums. There are several levels of court, including high courts, district courts, family courts, and summary courts, with the Supreme Court serving as the final court of appeal. Normally a trial begins at the district court level, and a verdict may be appealed to a higher court, and ultimately, to the Supreme Court. The government generally respected in practice the constitutional provisions for the right to a
speedy and
public trial by an impartial tribunal in all criminal cases. Although most criminal trials were completed within a reasonable length of time, cases occasionally took several years to work their way through the trial and appeals process. In July 2003, the Diet passed legislation aimed at reducing the average time required to complete criminal trials and civil trials that include witness examination. Its provisions include hiring substantial numbers of additional court and MOJ personnel, revising bar examinations, establishing new graduate law schools to increase the overall number of legal professionals threefold by 2010, and requiring that courts and opposing litigants jointly work to improve trial planning by allowing for earlier evidence collection and disclosure. The advisory panel on judicial reform released the official standards for setting up graduate law schools, and in March 2004, 68 universities (22 public and 46 private) opened new law schools. The July 2003, law also makes the Supreme Court responsible for accelerating proceedings in lower courts, imposes a 2-year time limit for courts to bring criminal and civil trials to conclusion, and requires the government to take the legal and financial measures necessary to accomplish these goals. A defendant is informed of the charges upon arrest and is assured a public trial by an independent civilian court with defense counsel and the right of cross-examination. There was no trial by jury; however, a judicial reform bill passed in May will allow serious criminal cases to be tried by a six-person, randomly selected jury and panel of judges. The law was scheduled to take effect in 2009. The defendant is presumed innocent. The Constitution provides defendants with the right not to be compelled to testify against themselves as well as to free and private access to counsel; however, the Government contended that the right to consult with attorneys is not absolute and can be restricted if such restriction is compatible with the spirit of the Constitution. Access sometimes was abridged in practice; for example, the law allows prosecutors to control access to counsel before indictment, and there were allegations of coerced confessions. Defendants are protected from the retroactive application of laws and have the right of access to incriminating evidence after a formal indictment. However, the law does not require full disclosure by prosecutors, and material that the prosecution does not use in court may be suppressed. Critics claimed that legal representatives of defendants did not always have access to all needed relevant material in the police record. A defendant who is dissatisfied with the decision of a trial court of first instance may appeal to a higher court. No guidelines mandate the acceptable quality of communications between judges, lawyers, and non-Japanese speaking defendants, and no standard licensing or qualification system for certifying court interpreters exists. A trial may proceed even if the accused does not understand what is happening or being said. Foreign detainees frequently claimed that police urged them to sign statements in Japanese that they could not read and were not translated adequately. As of May 2019, Japan has not signed nor ratified the
First Optional Protocol to the International Covenant on Civil and Political Rights and
Second Optional Protocol to the International Covenant on Civil and Political Rights. There were no reports of political prisoners.
Other issues • The Constitution does not prohibit arbitrary interference with
privacy, family, home, or correspondence but prohibit them by
case law on interpretation on Article 13 of the Constitution, and the government generally respects these prohibitions in practice. In April 2003, the Public Security Investigation Agency extended surveillance of the terrorist group Aleph (formerly known as
Aum Shinrikyo) because the government declared the group still posed a danger to society. In 2002, the
Defense Agency confirmed reports that it had violated a law protecting personal information when it compiled lists of citizens seeking official documents. A privacy bill to prevent such actions passed the Diet on May 2, 2003. • The government's attitude regarding international and nongovernmental investigation of alleged violations of human rights is generally cooperative and responsive to human rights groups' views, although the government restricts their access to detention facilities. A number of domestic and international human rights groups generally operated without governmental restrictions, investigating and publishing their findings on human rights cases. Government officials generally were cooperative and responsive to their views, although the Government restricted access by human rights groups to detention facilities. • In December 2008
United Nations Human Rights Committee gave a recommendation to Japan relating to public welfare in Article 12 and 13 of the Constitution that "while taking note of the State party's explanation that 'public welfare' cannot be relied on as a ground on placing arbitrary restrictions on human rights, the Committee reiterate its concern that the concept of 'public welfare' is vague and open-ended and may permit restrictions exceeding those permissible under the Covenant (art. 2)." == Civil liberties ==
