Four commercial vessels, including a Japanese oil supertanker, successfully transited the Strait of Hormuz despite Iran’s recent blockade, according to ship tracking data reported by media outlets.
The Panama-flagged tanker Idemitsu Maru, carrying roughly two million barrels of Saudi crude, departed the Persian Gulf and passed near Iran’s Larak island without reported interference.

Tracking data cited by the report showed the vessel had been anchored near Abu Dhabi before resuming its journey. Analysts have previously described Larak island as a checkpoint where Iranian authorities may impose transit costs, though it remains unclear if any payment was made.
Three additional ships, including a Chinese tanker, a container vessel linked to Iran, and a Turkish cargo ship, also exited the Gulf. One tanker reportedly switched off its tracking system during transit.
The development comes days after Iran’s Revolutionary Guard seized commercial vessels, raising concerns over maritime security in the region.
