Japanese Prime Minister Takaichi and Iranian President Pezeshkian held a telephone conversation on Wednesday to discuss maritime security and nuclear diplomacy.

The call comes at a time of heightened tension in the Middle East, where the stability of global energy supplies depends on the openness of key waterways.

This conversation marked the first direct communication between the two leaders in approximately two months [1]. During the call, Prime Minister Takaichi said free and safe navigation through the Strait of Hormuz without additional costs is necessary. She requested that Iran engage in thorough discussions with the international community, including nations that utilize the strait, to ensure continued stability.

Beyond maritime security, the leaders addressed the stalled progress of nuclear negotiations. Takaichi said it is necessary for the U.S. and Iran to conduct discussions based on their memorandum of understanding to reach a final agreement on nuclear issues quickly.

President Pezeshkian said Iran's perspective on the situation. He provided details regarding Iran's interactions with Oman and the current outlook for the region.

The diplomatic outreach occurs amid volatile market conditions. Crude oil futures rose by approximately two percent [2], reaching their highest level in one month.

"Free and safe navigation is important... without additional costs."

Japan's diplomatic intervention highlights its vulnerability to disruptions in the Strait of Hormuz, a primary artery for its energy imports. By urging Iran to adhere to a memorandum of understanding with the U.S., Tokyo is attempting to stabilize the region through multilateral diplomacy to prevent further spikes in global oil prices.
