Second Japan-Linked Oil Tanker Safely Crosses Strait of Hormuz After Iran Talks

A second oil tanker linked to Japan has successfully sailed through the strategic Strait of Hormuz, as diplomatic efforts continue between Tokyo and Tehran to keep the critical energy route open despite rising regional tensions.

According to ship-tracking data, a Panama-flagged crude oil tanker managed by Japanese energy group ENEOS completed the passage on Thursday, marking the second Japan-linked vessel to transit the waterway since disruptions began earlier this year.

The vessel reportedly carried around 1.2 million barrels of Kuwaiti crude and 700,000 barrels of Emirati Das Blend oil and is now heading toward Asia.

Japanese Prime Minister Sanae Takaichi confirmed that she personally reached out to Iranian President Masoud Pezeshkian to secure safe passage for the vessel, underscoring Tokyo’s growing diplomatic engagement with Tehran over maritime security.

Japanese officials also stated that no transit fee was paid for the passage, although coordination with Iranian authorities was required to ensure the ship’s movement through the chokepoint.

The development follows an earlier passage in April by another Japan-linked tanker operated by Idemitsu Kosan, suggesting a pattern of limited but negotiated transits through the Strait as tensions in the Gulf persist.

The Strait of Hormuz remains one of the world’s most sensitive maritime corridors, carrying roughly one-fifth of global oil shipments. Disruptions in recent months have prompted global concerns over energy security and price stability, with several countries stepping up diplomatic efforts to ensure continued access.

Japan, which relies heavily on Middle Eastern crude, has been particularly affected and is reportedly seeking alternative supply routes while maintaining engagement with Gulf states and the United States.
