Japanese Prime Minister Sanae Takaichi said the nation is experiencing critical supply shortages and distribution bottlenecks of naphtha, a vital petroleum-derived chemical feedstock [1, 2].
This disruption threatens the stability of Japan's industrial sector, as naphtha serves as the primary raw material for plastics and various chemical products. The crisis stems from the prolonged closure of the Strait of Hormuz due to deteriorating conditions in the Middle East, which has severely hampered crude oil transport [2, 5].
During a cabinet meeting on April 30 [3], Takaichi said that while the total volume of resources may be sufficient, the materials are not reaching the necessary destinations. "There is a clog in distribution," Takaichi said [2]. She said the situation is one where resources "should be sufficient, but they are not arriving" [4].
To mitigate the crisis, the Japanese government began the second phase of releasing national petroleum reserves on May 1 [3]. These emergency measures are intended to stabilize the domestic market while long-term shipping alternatives are sought. Takaichi said the current reserves are sufficient to ensure supply "beyond the end of the year" [1].
However, the reality on the ground suggests a growing gap between government optimism and industrial capacity. In manufacturing hubs, particularly within Shizuoka Prefecture, plants are struggling to maintain production schedules [4]. Reports indicate that approximately 30% of the manufacturing sector is currently facing risks associated with naphtha shortages [3].
Industry officials and the Ministry of Economy, Trade and Industry are working to identify where the specific bottlenecks are occurring. While the government maintains that the overall supply is secure, the localized shortages continue to pressure chemical manufacturers who rely on a steady flow of feedstock, and avoid costly plant shutdowns [1, 2].
“"There is a clog in distribution,"”
The naphtha crisis highlights Japan's extreme vulnerability to geopolitical instability in the Middle East. Because the country relies heavily on the Strait of Hormuz for energy imports, a physical blockage creates a 'last-mile' distribution failure where national reserves exist but cannot be efficiently routed to specific industrial clusters. This suggests that strategic reserves alone are insufficient if the logistical infrastructure of the supply chain is compromised.
