Statement by Ambassador HIKIHARA Takeshi at the IAEA Board of Governors Meeting starting on Monday, 6 March 2023 Item 3: Nuclear Security Review 2023

Thank you Chair,

Japan appreciates the Director General’s report entitled “Nuclear Security Review 2023” and the technical briefing by DDG Evrard on this report.


Lack of nuclear security would create significant risk to peaceful nuclear activities, and Japan strongly supports the IAEA’s central role in international cooperation in nuclear security. The IAEA’s two comprehensive reports, “Nuclear Security Report” and the “Nuclear Security Review” serve to enhance effective international cooperation, by providing stakeholders with the updated information and perspective of this field. Japan also welcomes the Secretariat’s efforts to strengthen communication with Member States through consultations and briefings on nuclear security related topics, including the Nuclear Security Fund.

Japan supports the nuclear security priorities presented in the Nuclear Security Review. Let me briefly touch upon several issues among them: international legal instruments; nuclear security guidance; review missions and advisory services; capacity-building; and assistance regarding the nuclear security in Ukraine.

With regards to the international legal instruments, Japan strongly supports the universalization of the Convention on the Physical Protection of Nuclear Materials (CPPNM) and its Amendment, as a means of enhancing the international nuclear security framework.

On the nuclear security guidance, Japan has been actively participating in the discussions with the Secretariat and Member States on the development and update of IAEA’s Nuclear Security Series.

On the national level, Japan has been continuously taking steps to strengthen its nuclear security through reviewing laws and regulations, and utilizing IAEA review missions and advisory services. In this regard, Japan has benefitted greatly from the IAEA International Physical Protection Advisory Service (IPPAS) programme to enhance its nuclear security regime and looks forward to the next IPPAS mission in Japan scheduled in 2024.

Capacity building is also a key element of nuclear security. Japan welcomes that the establishment of the Nuclear Security Training Demonstration Centre (NSTDC) in Seibersdorf has been making progress. On our part, Japan has been contributing to capacity building by providing training courses, workshops and seminars at the Integrated Support Center for Nuclear Non-proliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency which has been working with the Agency for many years as IAEA Collaborating Centre for nuclear security.

On assistance regarding the nuclear security in Ukraine, I would not repeat what I mentioned under the Agenda Item 2. The points I made apply both to nuclear security and safety, but I would like to quickly reiterate that Japan strongly urges the Russian Federation to immediately cease all activities preventing the competent Ukrainian Authorities from fully controlling over all nuclear facilities and material within its internationally recognized borders, and that Japan firmly supports the IAEA’s efforts to provide support for the nuclear security of Ukraine’s nuclear facilities, including the continued presence of the IAEA Support and Assistance Missions.


The Nuclear Security Review provides Member States with an overview of the global trends in nuclear security and a better understanding of the Agency’s planned activities and priorities for the coming years. Japan requests the Secretariat to continue to produce this valuable document, while avoiding duplication of content with the Nuclear Security Report.

With these comments, Japan takes note of the document contained in GOV/2023/4.

Thank you.
