Japan and Iran discuss free passage through Hormuz

Japan’s prime minister and Iran’s president held phone talks on June 1 and June 2, 2026, focused on keeping ships moving through the Strait of Hormuz.

Japan said it wants free passage while Iran said it would work to ensure smooth transit for Japanese vessels, which matters because the waterway is a vital route for global oil and trade.

Tokyo framed the call as a push for free passage through Hormuz and urged flexibility in ongoing talks. Japanese officials signaled concern that any disruption in the strait could affect energy supplies and commercial shipping far beyond the region.

Iran

Tehran said it would work to ensure smooth passage for Japanese vessels through the Strait of Hormuz. The message presented Iran as willing to keep a key shipping lane open while wider regional tensions continue.

  • The Strait of Hormuz is only about 40 kilometers wide at its narrowest point.
  • Japan is one of the world’s largest importers of liquefied natural gas.
  • The strait has repeatedly been a flashpoint during Gulf crises because so much energy traffic depends on it.

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
