Environment Minister Ishihara asked citizens on Friday not to hoard household trash bags as some regions experience shortages [1].
The appeal follows supply chain instabilities for naphtha, a petroleum derivative used to produce polyethylene bags, caused by rising crude oil prices and volatility in the Middle East [1].
Shortages have already appeared in several municipalities across Japan, including Ichihara City in Chiba Prefecture [2, 3]. The government believes these shortages are being exacerbated by panic buying rather than a total lack of product. Data from major manufacturers shows that trash bag shipments in April were between 1.1 and two times higher than the previous year [1]. In some specific regions, purchase volumes reached up to three times the normal amount [1].
Ishihara said that the government is working to ensure that supply levels remain consistent with previous years. He said that continuous supply is possible and that the public should avoid unnecessary stockpiling to prevent further market distortion.
"Trash bags can be secured at the usual annual supply volume, and continuous supply is possible," Ishihara said [1].
He said the public should maintain a composed approach to consumption. "Please refrain from purchasing more than necessary and engage in calm consumer behavior," Ishihara said [1].
The ministry's effort to stabilize the market comes as the cost of raw materials continues to fluctuate. While the supply of naphtha has become unstable, the government maintains that the current production capacity is sufficient to meet standard household needs if demand does not spike unnaturally.
“"Trash bags can be secured at the usual annual supply volume, and continuous supply is possible."”
This situation highlights the vulnerability of Japan's domestic consumer goods to geopolitical instability in the Middle East. Because basic necessities like municipal trash bags rely on specific petrochemical precursors, a spike in crude oil prices can trigger a psychological chain reaction of panic buying. The government's intervention is aimed at decoupling the actual physical supply of plastic from the perceived scarcity driven by news of energy market volatility.
