The Hague Convention (Convention on the Civil Aspects of International Child Abduction)
Japan’s Conclusion of the Hague Convention and its Implementing Legislation
1. Japan’s Conclusion of the Hague Convention
Background to the development of the Convention
In the 1970s, with the rise in the number of cross-border relocation and international marriage, the issue of “child removal”, where one parent takes a child to their home country or a third country without the other’s consent, began to attract attention. This highlighted the need for an international code to resolve disputes over child custody. In this context, the Hague Conference on Private International Law (HCCH)
, established in the Netherlands in 1893 with the objective of working for the progressive unification of the rules of private international law, decided to deliberate on this issue in 1976, leading to the adoption of the Hague Convention on the Civil Aspects of International Child Abduction (Hague Convention) in October 1980.
Significance of Japan's conclusion of the Convention
Japan concluded the Hague Convention, and it entered into force in 2014. This was an event of great significance to the country in resolving issues related to the cross-border movement of children.
(1) Issues prior to concluding the Convention
Before the Hague Convention entered into force, parents whose children were removed from Japan to a foreign state shouldered immense burdens and difficulties, from locating their children to navigating trials in foreign courts, compounded by the difference in legal systems and cultures. Furthermore, Japanese citizens living abroad that wished to return to Japan temporarily with their children would encounter serious obstacles, such as the other parent refusing to give consent or a foreign court disallowing the children’s temporary return to Japan. These difficulties arouse due to the absence of a treaty-based mechanism to resolve cases where such temporary visits to Japan resulted in the child being retained there.
(2) Improvements after concluding the Convention and their real-world significance
- Ensuring international cooperation and support
Since the entry into force of the Hague Convention, parties involved in individual cases have been able to pursue procedures - with support from Central Authorities in countries concerned and Japan (the Ministry of Foreign Affairs) - to secure the return of a child wrongfully removed from Japan, or to facilitate contact with a child living abroad, in accordance with the international rules defined by the Convention. The Central Authorities of Contracting States provide various forms of support, such as locating children, lawyer referrals, and assistance with court proceedings, depending on specific circumstances of their respective countries. - Preventing troubles surrounding the return of Japanese nationals residing abroad
For Japanese citizens living abroad who wish to temporarily return to Japan with their child, Japan’s status as a Contracting State of the Convention has reduced the difficulty of obtaining the other parent’s consent or permission from a foreign court. This has contributed to averting disputes surrounding departures from the country of residence to Japan or other destinations. Furthermore, there is enhanced clarity about procedures for the resolution of issues under the Convention, such as mediation and litigation, if one parent returns to Japan with a child without the other parent’s consent, and various forms of assistance provided by the Japanese Central Authority have become readily accessible. - Deterrence effect for issues related to the cross-border movement of children
Widespread awareness of the Convention’s principle regarding the return of children to the state of their habitual residence has served as a deterrent to parents who may have otherwise acted without careful consideration to move a child across borders without the other parent's consent. - Promoting cross-border contact with children
Having become a Contracting State of the Convention, parties involved in individual cases can benefit from the support of Central Authorities in other nations in ensuring that parents and children living across borders have ample opportunities to maintain contact with each other.
Conclusion of the Hague Convention
The Japanese Government established Meeting of Parliamentary Senior Vice-Ministers of related government agencies in January 2011 to deliberate on Japan’s conclusion of the Hague Convention. Discussions focused on issues such as ensuring consistency with the domestic legal system, facilitating the safe return of a child, and establishing a Central Authority, carefully considering various perspectives and opinions expressed including by both proponents and opponents. As a result, the Government came to the conclusion that concluding the Hague Convention would have significance. Consequently, on May 20, 2011, the Cabinet approved preparations for the conclusion of the Hague Convention and decided to establish a Central Authority within the Ministry of Foreign Affairs as the focal point to facilitate applications for assistance in child’s return and other procedures concerning the return of a child. The Ministry of Justice and the Ministry of Foreign Affairs drafted the Implementation Act bill, taking into account the outcomes of the discussion with stakeholders and specialists.
At the 183rd Ordinary Session of the Diet, on May 22, 2013, the draft approval for the conclusion of the Convention on the Civil Aspects of International Child Abduction (the Hague Convention) was adopted, and on June 12, 2013, the Act for Implementation of Convention on the Civil Aspects of International Child Abduction (the Implementation Act) was enacted into law.
In response to the adoption and enactment of the Convention and the Implementation Act, the Cabinet made approval on signature, conclusion and promulgation of the Convention, and the Government of Japan signed the Convention and submitted the instrument of acceptance to the Ministry of Foreign Affairs of the Netherlands on January 24, 2014. Consequently, the Hague Convention came into effect for Japan on April 1st of 2014.

2. Overview of the Implementation Act
(1) Content
The Implementation Act establishes domestic procedures and other matters required to implement the Hague Convention.
The Implementation Act designates the Minister for Foreign Affairs as the Central Authority and defines its authority. It also prescribes court procedures (Procedure of Return of the Child) required to decide whether the child should be returned to the state where the child held habitual residence before he or she was removed.
In May 2019, the bill for partially amending the Implementation Act (“the Bill for Partially Amending the Civil Execution Act and the Act for Implementation of the Convention on the Civil Aspects of International Child Abduction”) was approved in the 198th ordinary session of the Diet, and the amended Implementation Act took effect on April 1, 2020.
The procedures for compulsory execution of court orders to return a child were amended to further ensure their effectiveness. For instance, the amended Implementation Act has made it possible to file a petition for execution by substitute without first requiring indirect execution, under certain conditions. Previously, indirect execution was mandatory before a petition for execution by substitute could be filed. In addition, the amended Implementation Act has made it possible to secure the release of a child even when the child is not with the obligor, a person who is obligated to return a child, though the presence of the oblige in principle is necessary. Previously, the release of a child was only possible when the child was physically with the obligor.
