Japanese supermarkets began removing free roll-type plastic bags from stores on Friday, May 15, 2026 [1].
The move signals a growing crisis in the plastic supply chain, where raw material shortages are now impacting daily consumer conveniences and broader industrial production.
Retailers, including Maruko Store, have stopped providing these bags due to a scarcity of naphtha, a petroleum-derived raw material [1]. The shortage is attributed to ongoing instability in the Middle East, which has disrupted the flow of essential petrochemicals [1].
Satoshi Yamakawa, president of Maruko Store, said plastic products, including shopping bags, are in a state of shortage due to the influence of the situation in the Middle East [1]. The impact extends beyond retail; the shortage has reportedly affected other sectors, such as mushroom cultivation, which relies on plastic packaging [1].
Other industries have already felt the pressure of the "naphtha shock." For instance, TOTO began suspending new orders on April 13, 2026 [3]. Some reports indicate that annual packaging cost burdens have reached approximately 3 million yen [4].
Customers have expressed frustration over the sudden loss of these amenities. One shopper said many people had been helped by the bags, and that citizens are the ones who suffer during these geopolitical situations [1].
Despite the retail shortages, the Japanese government maintains that the national energy supply remains stable. Minister of Economy, Trade and Industry Akazawa said Japan has secured the necessary volume of crude oil and petroleum-related products through the release of petroleum reserves and alternative procurement from various countries [1].
“Plastic products, including shopping bags, are in a state of shortage due to the influence of the situation in the Middle East.”
The removal of plastic bags is a visible symptom of a deeper industrial vulnerability. While the Japanese government can stabilize bulk energy imports like crude oil, the specialized chemical supply chain for naphtha is more fragile. The ripple effect—stretching from supermarket bags to TOTO's manufacturing and agricultural packaging—suggests that geopolitical volatility in the Middle East is directly translating into operational halts for Japanese domestic industries.
