Japan-bound oil tanker clears Hormuz after weeklong Gulf halt

Idemitsu Maru heads to Nagoya after Iranian-approved passage, marking the first Japan-bound crude tanker to exit the Persian Gulf since Feb. 28.

  • The Idemitsu Maru, a Japan-bound oil tanker, has successfully passed through the Strait of Hormuz after being anchored in the Persian Gulf for a week.
  • This marks the first direct passage of a Japanese crude tanker from the region since recent military operations began, with the vessel receiving approval from Iranian authorities.
  • While Japan's Prime Minister welcomed the passage as a positive development, more than 40 other Japan-related vessels remain in the Persian Gulf.

A crude oil carrier linked to Idemitsu Kosan Co. is on its way to Japan after crossing the Strait of Hormuz, marking the first direct Japan-bound crude tanker to leave the Persian Gulf since US-Israeli military operations against Iran began on February 28.

The vessel, Idemitsu Maru, is owned by Idemitsu Tanker Co., a subsidiary of Japanese oil refiner Idemitsu Kosan Co. Japanese Prime Minister Sanae Takaichi said on X, formerly Twitter, on Wednesday (April 29) that a Japan-related ship had cleared the strait and was sailing towards Japan.

Takaichi called the passage a positive development, including for “the protection of Japanese citizens”, and said she would continue pressing Iran to ensure that “all ships” can pass through the key oil transport waterway “freely and safely”.

More than 40 Japan-related vessels are still in the Persian Gulf.

According to global ship-tracking website MarineTraffic, the Idemitsu Maru was in the northern Arabian Sea as of Wednesday afternoon Japan time after passing through the Strait of Hormuz. It was heading for Nagoya in central Japan. Iranian state media also reported the tanker’s passage through the strait.

Reports said the Idemitsu Maru is transporting 2 million barrels of crude oil from Saudi Arabia. The tanker had stayed anchored off Abu Dhabi, capital of the United Arab Emirates, for a week before departing on Monday and passing through the strait with approval from Iranian authorities. It remains unclear whether the recently imposed Iranian transit fees were paid.

On Wednesday, the Iranian Embassy in Japan also posted on X a message featuring a photo of the Idemitsu Kosan tanker Nissho Maru, which carried Iranian crude oil to Japan in 1953 during a British maritime blockade. The embassy said the mission “stands as a testament to the long-standing friendship between the two countries”, adding, “This legacy continues to hold great significance.”
