Japan’s crude oil imports fell 59% month over month to 900,000 barrels per day in April, according to the provided report. The decline followed the outbreak of the Iran war and the closure of the Strait of Hormuz, one of the world’s most important maritime chokepoints for oil flows. The move is especially significant for Japan because the country relies on the Middle East for more than 90% of its oil supply, leaving it highly exposed to disruptions in the region.
