1. Japan and the United States reaffirm our commitment to seek the peace and security of a world without nuclear weapons and to the Nuclear Non-Proliferation Treaty (NPT). We commit to work together for a successful Review Conference in New York that strengthens each of the Treaty's three pillars: nuclear disarmament, nuclear non-proliferation, and peaceful uses of nuclear energy. The NPT remains the cornerstone of the global non-proliferation regime and an essential foundation for the pursuit of nuclear disarmament. In this 70th year since the atomic bombings of Hiroshima and Nagasaki, we are reminded of the catastrophic humanitarian consequences of nuclear weapons use. Hiroshima and Nagasaki will be forever engraved in the world's memory. Concerns over the use of nuclear weapons underpin all work to reduce nuclear dangers and to work toward nuclear disarmament, to which all NPT parties are committed under Article VI of the Treaty. We affirm that it is in the interest of all States that the 70-year record of non-use should be extended forever and remain convinced that all States share the responsibility for achieving this goal.

2. We reaffirm our commitment to a step-by-step approach to nuclear disarmament, and recognize the progress made since the height of the Cold War. We recognize that further progress is needed. Immediate next steps should include further negotiated nuclear reductions between the United States and Russia, the immediate start of multilateral negotiations of a Fissile Material Cutoff Treaty, entry into force of the Comprehensive Nuclear-Test-Ban Treaty and the protocols to the existing nuclear weapon free zone treaties, and the continued reduction of all types of nuclear weapons, deployed and non-deployed, including through unilateral, bilateral, regional and multilateral measures. We further emphasize the importance of applying the principles of irreversibility, verifiability and transparency in the process of nuclear disarmament and non-proliferation. In this regard, the United States welcomes Japan's leadership in the Non-proliferation and Disarmament Initiative and Japan's role as the Co-Chair Country for the Conference on Facilitating the Entry into Force of the CTBT, and Japan welcomes the U.S. initiative to launch the International Partnership on Nuclear Disarmament Verification. We affirm our readiness to cooperate closely on this new initiative, which will facilitate further cooperation between the nuclear-weapon States and non-nuclear-weapon States with respect to nuclear disarmament efforts.

3. We further note the positive role played by civil society, and hope that activities such as the UN Conference on Disarmament Issues and the Comprehensive Nuclear-Test-Ban Treaty's Group of Eminent Persons Meeting, both to be held in Hiroshima in August, and the Pugwash Conference to be held in Nagasaki in November, will strengthen momentum toward disarmament and non-proliferation.

4. We unequivocally support access to nuclear technology and energy for peaceful purposes by states that comply with their non-proliferation obligations. We are especially pleased to announce that both the United States and Japan which strongly support the role of the International Atomic Energy Agency (IAEA) in promoting the benefits of the peaceful uses of nuclear technology have pledged to extend their financial support to the IAEA Peaceful Uses Initiative over the next five years. The U.S. pledge of $50 million and Japan's pledge of $25 million will ensure that applications of nuclear science and technology continue to advance medical care and health improvement including cancer treatment and Ebola diagnosis, food and water security, clean oceans and disease eradication in regions of the world most in need.

5. The IAEA safeguards system is a fundamental element of that framework and plays a critical role in preventing and addressing challenges to the global non-proliferation regime, by verifying that states are not diverting peaceful nuclear energy programs to develop weapons, and by responding to cases of non-compliance. We call on all states that have not yet done so to adhere to a Comprehensive Safeguards Agreement and the Additional Protocol as the recognized IAEA safeguards standard, and renew our willingness to assist states to implement safeguards agreements. We support the evolution of IAEA safeguards at the State level, and emphasize the importance of maintaining the credibility, effectiveness and integrity of the IAEA safeguards system. To preserve the future integrity of the NPT, action is needed to discourage any state from withdrawing from the Treaty as a way to escape its responsibilities or to misuse the fruits of peaceful cooperation with other states, as well as to encourage States Parties to remain in the Treaty by demonstrating tangible progress in all three pillars of the Treaty.

6. We underscore the imperative of addressing challenges to the integrity of the NPT and the non-proliferation regime posed by cases of noncompliance. We welcome the EU/E3+3 deal with Iran and encourage completion of the work that remains to fully resolve the international community's concerns regarding the exclusively peaceful nature of Iran's nuclear program as well as to ensure that Iran does not acquire nuclear weapons. We also remain committed to a diplomatic process to achieve North Korea's complete, verifiable and irreversible denuclearization. We urge North Korea to take concrete steps to honor its commitments under the 2005 Joint Statement of the Six-Party Talks, fully comply with its obligations under the relevant UNSC Resolutions, refrain from further provocation including nuclear tests and ballistic missile launches, return to the NPT and IAEA safeguards, and come into full compliance with its nonproliferation obligations.

7. We also underscore the importance of promoting stringent export control in Asia and globally. We are determined to continue to work together to conduct outreach activities for Asian countries with a view to further enhancing their export control capacity as well as to promoting recognition that rigorous export controls foster confidence of trade or investment partners, and create a favorable environment for further economic growth rather than impeding trade and investment.
