A shortage of naphtha is disrupting Japanese supply chains and altering the availability of products at retail stores across the country.
This crisis threatens the stability of Japan's industrial base. Because naphtha is a critical raw material for plastics and chemicals, any prolonged shortage can lead to widespread product scarcity and increased costs for consumers.
The supply disruption stems from escalating geopolitical tensions in the Middle East. Specifically, a de-facto blockade of the Strait of Hormuz has restricted the flow of crude oil and naphtha into the region [3]. This bottleneck has forced manufacturers and distributors to seek alternative procurement strategies to maintain operations.
The scale of the impact is significant. Approximately 46,741 Japanese manufacturing firms, representing about 30% of the sector, face procurement risks due to the shortage [1]. The instability extends further down the supply chain, where more than 40,000 companies in secondary distribution have been identified as at risk [2].
Retailers are already seeing the effects on store shelves. As manufacturers struggle to source raw materials, the variety and availability of certain retail products have begun to change. Industry leaders said they are implementing measures to limit the impact on the general public, though the effectiveness of these steps depends on the restoration of shipping routes.
These events were reported in April 2024, as the industry attempted to quantify the risk posed by the Middle East instability [1], [2]. The situation highlights the vulnerability of Japan's energy-dependent manufacturing sector to regional conflicts far from its shores.

The crisis underscores Japan's acute dependency on Middle Eastern energy corridors. The fact that nearly one-third of manufacturing firms are at risk suggests that a blockade of the Strait of Hormuz creates a systemic failure point for the Japanese economy, where a geopolitical event in one region directly dictates product availability in domestic retail stores.
