Japan's Auto Industry Throttled by Middle East Conflict

(MENAFN) More than a month into the Middle East conflict, Japan's automotive sector finds itself in a deepening bind — raw material shortages are inflating production costs, while shipping paralysis has forced carmakers to slash or suspend output destined for the region.

Data from trade intelligence firm Kpler revealed that Japan's imports of petroleum products, including naphtha, plunged roughly 30% in March compared to the previous month — a decline with cascading consequences throughout the automotive supply chain.

Naphtha, a vital feedstock for the chemical industry, underpins the production of plastic components such as ethylene. Its growing scarcity has triggered shortages of critical auto parts, while prices of butadiene and synthetic rubber — the foundational materials for tire manufacturing — have spiked sharply.

Tang Jin, a senior researcher at Japan's Mizuho Bank and automotive sector specialist, warned that the fallout is both direct and far-reaching. Tighter naphtha supplies are pushing up costs across a broad range of auto parts and tires, he said, eroding manufacturer margins and steadily undermining the global competitiveness of Japanese vehicles.

The damage extends beyond the factory floor. The Middle East represents a strategically important export market for Japanese carmakers, but shipping disruptions, delivery delays, and order cancellations have thrown production schedules into disarray — compelling several manufacturers to curtail or halt output of models bound for regional customers.

The production cuts among major automakers have been substantial. Japanese media reported that Toyota Motor Corp. plans to reduce Middle East-bound vehicle production by 24,000 units in April alone. Nissan Motor Co. announced it would carry forward into April the output reductions already enacted in March. Mazda Motor Corp. confirmed a complete halt to Middle East export production through the end of May, while Subaru Corp. disclosed that shipments to the region had already ceased entirely due to blockages through the Strait of Hormuz.

With Iran and the United States having reached a two-week ceasefire and safe passage through the Strait of Hormuz anticipated to resume, industry insiders remain cautious. Most are adopting a wait-and-see posture, noting it is still too early to gauge how durably the situation will improve — or whether the truce will hold long enough to meaningfully restore supply chains.
