Refining Infrastructure Limits Non-Middle Eastern Alternatives

The Japanese government is confronting a structural crisis as the closure of the Strait of Hormuz cuts off 93% of the nation's crude oil imports. While global suppliers like the United States offer potential alternatives, energy experts warn that Japan’s domestic refining infrastructure is specialized for the specific chemical composition of Middle Eastern crude. According to Go Matsuo, head of the Energy Economics and Society Research Institute, Japanese refineries are designed to process the unique qualities of Middle Eastern oil, which is also significantly cheaper than U.S. variants. Transitioning to different raw materials would not only increase costs but could require extensive and time-consuming modifications to existing refinery hardware, complicating efforts to secure a quick fix for the supply gap.

Government Contemplates Mandatory Consumption Curbs

Prime Minister Sanae Takaichi has indicated that the administration is monitoring the depletion of national reserves, which currently hold enough oil to cover approximately eight months of domestic consumption. During recent parliamentary questioning, Takaichi noted that the government might soon be forced to ask for public cooperation in reducing electricity and petroleum use. While official mandates have not yet been issued, the International Energy Agency (IEA) has already proposed a ten-point plan for advanced economies. These recommendations include reducing highway speed limits, mandating remote work for three days a week, and implementing car-free Sundays in major cities to cut global demand by an estimated 2.7 million barrels per day.

Naphtha Shortages Threaten Household Retail Stability

The crisis extends far beyond the fuel pump, as the shortage of naphtha—a hydrocarbon liquid processed from crude oil—threatens the production of plastics and synthetic rubbers. This chemical bottleneck is expected to impact a wide array of mass-produced consumer goods, including detergents, sanitary products, and plastic packaging. Professor Masatoshi Kojima of Momoyama Gakuin University warned that if the disruption continues for more than four months, the retail sector will face unavoidable price spikes. Everyday items such as disposable diapers and bottled beverages are among the first products likely to see cost increases as manufacturers...
