Ministry of Justice

The Ministry of Justice of Japan is responsible for overseeing the nation’s judicial system, including the supervision of courts, public prosecutors, and legal aid services. It manages the correctional administration, operating prisons and rehabilitation facilities aimed at offender reintegration. The ministry also handles immigration control, regulating entry, residency, and deportation of foreign nationals in accordance with Japanese law. Additionally, it maintains family registers, real estate registries, and corporate registrations, providing essential civil documentation services. Through its Legal Affairs Bureau network, the ministry delivers legal consultation and support to citizens and businesses across the country. It plays a central role in drafting legislation related to civil, criminal, and administrative law, ensuring coherence with constitutional principles. The ministry also coordinates international legal cooperation, including extradition treaties and mutual legal assistance requests.

Headquartered in Tokyo, the Ministry of Justice operates as a core component of Japan’s executive branch, reporting directly to the Prime Minister and the Cabinet. As a national ministry, its authority extends throughout all prefectures, overseeing a nationwide network of regional bureaus and institutional facilities. Its distinguishing attribute lies in its dual function as both a judicial administrator and a regulatory authority for immigration and civil registration. The organization is staffed by career civil servants appointed under the national public service system, ensuring continuity and expertise. While specific employee numbers or budget figures are not provided in the source material, its structural position places it among the key ministries shaping Japan’s legal and social framework. The ministry’s incident history includes a 2023 DDoS attack claimed by Anonymous that temporarily disrupted its online services, highlighting its exposure to cyber threats despite its primarily administrative focus.
