A crude oil tanker destined for Japan has successfully navigated the Strait of Hormuz, according to a Reuters report published today, which cited data from LSEG. This marks only the second Japan-bound vessel to traverse the chokepoint since the United States and Israel initiated strikes against Iran at the end of February.
Reuters, citing data from Kpler, further reported that the tanker holds 1.2 million barrels of Kuwaiti crude oil and an additional 700,000 barrels of crude from the United Arab Emirates. Kpler indicated that these cargoes were loaded during late February. The vessel is owned by the Japanese company Eneos. No information was provided regarding any potential agreement between Eneos and Iranian authorities that allowed the tanker to pass. Reuters noted in its report that the tanker, named the Eneos Endeavour, had switched off its transponder while moving through the strait.
Deactivating location devices has become a common practice for vessels in the Persian Gulf to evade detection by the Iranian military and reduce the risk of attack. Last week, three supertankers carrying Iraqi and Emirati oil successfully left the Strait of Hormuz, all with their transponders turned off. However, 42 container ships remain stranded in the strait, while nine have managed to exit. Two vessels have been seized by Iranian authorities.
Japan, which has limited domestic energy resources, relies heavily on oil supplies from the Middle East. The country experienced an immediate supply disruption, as most shipments from the region remained trapped at the Strait of Hormuz. Japanese refiners depend on Middle Eastern imports for approximately 95% of their crude oil feedstocks, with most oil originating from Saudi Arabia, Kuwait, the United Arab Emirates, and Qatar. Of these supplies, roughly 70% typically arrive in Japan via tankers transiting the Strait of Hormuz.
