Japan is experiencing an escalating shortage of naphtha, a key feedstock for petrochemicals and plastics, with impacts spreading across industrial sectors. The trend has intensified over recent months, raising concerns among manufacturers reliant on the material.
The shortages stem from a combination of reduced domestic refining capacity and shifting global supply dynamics. As Japan's refineries have closed or scaled back, imports have not fully compensated, leaving critical industries exposed to price volatility and supply gaps.
Data from Nippon.com indicates naphtha production in Japan fell 12% year-on-year in the first quarter of 2025, while imports declined 8% over the same period. Demand, however, has remained relatively stable, widening the supply deficit.
If the trend continues, petrochemical companies may face production slowdowns, potentially raising costs for downstream products like plastics and synthetic fibers. This could ripple through auto manufacturing, electronics, and packaging industries, which rely on naphtha-derived materials.
Analysts warn that without policy intervention or new import agreements, the shortage may persist through 2026. Some industry groups advocate for stockpiling measures and temporary tariff relief to ease immediate pressures.
