Message from the Foreign Minister

June 18, 2026

On June 18 (Japan Standard Time), the United States and Iran signed a Memorandum of Understanding and the cessation of hostilities was declared. Japan once again welcomes the fruition of the diplomatic efforts made by the parties as well as the countries that played a role in mediation.

Hereafter, it is important that free and safe navigation through the Strait of Hormuz is swiftly reestablished through the steady implementation of this MoU by all parties. Japan also considers it of critical importance that vessels be able to transit the Strait of Hormuz without being subject to additional costs, as has been the case thus far.

Japan strongly hopes that a final agreement on matters such as Iran's nuclear issue will be achieved as soon as possible through further negotiations between the United States and Iran. Japan will also support the peaceful resolution of the Iranian nuclear issue including through coordination with the International Atomic Energy Agency (IAEA).

After the conclusion of a final agreement, Japan intends to play an active role in the reconstruction and recovery of the region. Japan will also continue to make every diplomatic effort, in close coordination with the international community, toward the realization of peace and stability throughout the Middle East region.
