A shortage of naphtha is disrupting the production of packaging and disaster-relief materials across Japan, leading to price increases and stockouts [1, 2].
This supply chain failure threatens critical infrastructure and public health, as the shortage affects everything from daily food packaging to emergency equipment used in natural disasters. Because naphtha is a primary feedstock for plastics and chemical solvents, its scarcity ripples through multiple industrial sectors.
The crisis stems from reduced naphtha imports caused by worsening geopolitical tensions in the Middle East [3, 4]. These disruptions have limited the availability of naphtha-derived inks and solvents, which are essential for printing and manufacturing containers [2].
Manufacturers are feeling the impact in multiple prefectures. In Okayama Prefecture, Hagiwara Kogyo has seen disruptions in the production of blue sheets, which are essential for disaster relief. In Miyagi Prefecture, the bakery Pan Kobo Sanpodou has faced shortages of bread bags [1].
Financial impacts began in April 2024, when price increases of 15% were applied to affected products [1]. While some reports suggested Japan could run out of the material by June 2024 [5], other sources indicated that necessary volumes remained sufficient [5].
The outlook for supply remains uncertain after July 2024 [1]. However, Okayama Governor Ihara said a procurement plan had been established for the remainder of the year [3].
Local governments have been forced to implement emergency measures. In several Miyagi cities, municipal waste-bag programs were affected. Local authorities said they would begin accepting non-designated garbage bags on May 20, 2024, to manage the shortage [6].
TBS NEWS DIG caster Masatoshi Namba said the naphtha supply shortage is also affecting summer essentials [1].
“A shortage of naphtha is disrupting the production of packaging and disaster-relief materials across Japan.”
The naphtha shortage highlights Japan's vulnerability to Middle Eastern geopolitical instability due to its heavy reliance on imported petroleum feedstocks. Because naphtha is the foundation for the plastics and chemical industries, the disruption of 'low-tech' items like bread bags and blue sheets serves as an early warning sign for potential broader industrial failures in the petrochemical sector.
