Statement by H.E. Ambassador YAMAZAKI Kazuyuki, Permanent Representative of Japan to the United Nations, at the High-level Plenary Meeting to Commemorate and Promote the International Day against Nuclear Tests
2026/8/31
(As delivered)
Mr. President,
Japan aligns itself with the statement delivered by Australia on behalf of the Friends of the CTBT.
This year marks the 30th anniversary of the opening for signature of the CTBT. Over the past three decades, it has helped establish a strong global norm against nuclear test explosions and advanced nuclear disarmament and non-proliferation.
As the only country to have suffered atomic bombings during war, Hiroshima and Nagasaki, Japan remains firmly committed to a world without nuclear weapons and free of nuclear test explosions.
Japan urges all States that have not yet done so, particularly the remaining Annex 2 States, to sign and ratify the Treaty without further delay.
Mr. President,
A strong verification regime is essential for the credibility of the CTBT. To sustain it, we strongly call on all States Signatories to pay their assessed contributions timely and in full to keep the system in continuous function.
Japan has long supported capacity-building through JICA’s Global Seismological Observation Training Course, which has trained more than 300 experts from over 80 countries.
Japan welcomes the Kingdom of Tonga’s ratification as a milestone for universalization in the South Pacific. We also commend Executive Secretary Dr. Robert Floyd for his tireless efforts to advance the universalization of the Treaty and strengthen its verification regime.
Japan remains seriously concerned about North Korea’s nuclear and missile programs. We reiterate our condemnation of its six nuclear tests and urge them to refrain from any further nuclear test, comply with relevant Security Council resolutions, and sign and ratify the CTBT.
Mr. President,
On September 22, during UN General Assembly High Level Week, the Friends of the CTBT will convene the Ministerial Meeting. We call for high-level participation and support for the joint statement. We hope this meeting will renew political momentum toward the Treaty’s early entry into force and universalization.
Japan will continue to work toward a world without nuclear weapons and nuclear test explosions.
I thank you.
