CTBTO準備委員会第69会期作業部会Aステートメント（菊地信之公使参事官）（英語ページへのリンク）
令和8年5月18日
Madam Chair, distinguished delegates,
Thirty years ago, the world made a solemn choice: to bring nuclear testing to an end. From that moment, States Signatories have worked with steadfast resolve to build a robust verification regime. Today, more than 90 percent of the 337 facilities of the International Monitoring System stand installed across the globe. This is no small accomplishment.
Yet after three decades, the IMS now faces the wear of time itself. Without timely and adequate recapitalization, its ability to monitor continuously, let alone to detect nuclear tests, may erode. The credibility of the CTBT rests upon the strength of the IMS.
For strength of system must be matched by strength of people, Japan has long conducted the Global Seismological Observation Training Course, thereby fostering the skill and readiness of National Data Centres; and our commitment does not waver.
As we consider the 2027 budget, we must identify activities that are truly essential, reconsider priorities carefully, and work toward a shared understanding. WGA is the proper forum for this. Japan urges the PTS to pursue greater efficiency in budgetary management and institutional operations. On assessed contributions, it bears recalling that nearly 80 percent of the CTBT’s budget is devoted to the verification regime—plain proof of the need for timely payment. Japan has already met its share in full and calls upon all States to do likewise.
Madam Chair,
At a time of growing geopolitical tension, the CTBT remains one of the few practical instruments through which the international community may preserve restraint. This has been also expressed by many countries at the NPT Review Conference, currently held in NY. Japan stresses the importance of transparency, accountability, and confidence-building measures for strengthening the effectiveness of banning nuclear weapon test explosions.
North Korea’s nuclear issue is not merely a regional concern but a global challenge that strikes at the very core of the CTBT’s purpose and verification mandate. Hence we must continue to take up this issue at the Prep Com and Working Groups. Japan expresses serious concerns over the advancement of North Korea’s nuclear and missile development. We urge North Korea not to conduct any further destabilizing or provocative actions, including a nuclear test. Japan also urges North Korea to comply with its obligations under the relevant UN Security Council resolutions, to return to full compliance with the NPT and to sign and ratify the CTBT at the earliest possible date. Japan reiterates its firm dedication to achieving the complete denuclearization of North Korea in accordance with the relevant UNSC resolutions and remains resolute in upholding its crucial responsibilities toward this goal.
Madam Chair,
In a world marked by doubt and division, the CTBT remains proof that nations, acting together, can still give shape to hope. Under the banner of “One Treaty, One Goal—Zero Tests,” Japan stands united with all States Signatories in pursuit of lasting peace.
Thank you.
