The shift to monochrome will be a small but tangible reminder
In the long chain that connects distant wars to daily life, Japan's largest snack maker has become an unlikely symbol of geopolitical consequence. Calbee, born from the ashes of postwar Hiroshima and grown into a global snack empire, will strip the color from fourteen of its flagship products by month's end — not by design, but by necessity. A blockade of the Strait of Hormuz has tightened Japan's access to naphtha, the petroleum derivative that gives printing ink its vibrancy, reminding consumers that the costs of conflict are rarely confined to the battlefield.
- The Iran war's disruption of Strait of Hormuz shipping has quietly strangled Japan's supply of naphtha, a petroleum-derived ink ingredient the country draws 40% of from the Middle East.
- Calbee — a $2 billion global company whose colorful packaging is itself a form of brand currency across Asia, Europe, and the United States — has been forced to choose monochrome over delay.
- The pivot landed as a cultural jolt: headlines spread nationwide, arriving just after a separate snack maker had halted production over heavy oil shortages, signaling how deeply the conflict has threaded into ordinary commerce.
- Calbee's stock slipped over 1% on the news, even as the broader Nikkei climbed, marking the company as a visible casualty in an otherwise managed economic narrative.
- The Japanese government moved swiftly to reassure the public, citing tripled non-Middle Eastern imports and stockpiled crude, insisting critical supply chains remain intact — even as a snack aisle tells a quieter, more colorless story.
By the end of May, fourteen of Calbee's flagship snack products — many of them potato chips long recognized for their vivid, eye-catching bags — will appear on Japanese store shelves in black and white. The change is not a rebrand. It is the visible imprint of a war being fought thousands of kilometers away.
The connection runs through naphtha, a petroleum derivative essential to printing ink. When the Iran war erupted in late February and disrupted shipping through the Strait of Hormuz, Japan's access to the material tightened sharply. With roughly 40% of its naphtha sourced from the Middle East, Japan's printing industry felt the pressure almost immediately — and Calbee, whose brand identity is built on colorful packaging sold across Asia, Europe, and the United States, found itself with few options.
The news arrived alongside reports that another snack manufacturer had briefly halted production of a popular crisp, citing difficulties securing heavy oil for its factories. Together, the incidents illustrated how thoroughly the Middle East conflict had penetrated Japan's supply chains — even at the level of potato chips.
Founded in Hiroshima in 1949 as the city was still rebuilding from atomic devastation, Calbee has grown into a global enterprise with 2025 sales of 322.5 billion yen and ownership of British brand Seabrook Crisps. Its stock dipped more than 1% on the packaging news, even as the broader Nikkei rose.
The Japanese government moved quickly to steady the narrative. Senior spokesperson Kei Sato issued a statement — broadcast as an emergency bulletin by some networks — confirming that naphtha imports from outside the Middle East had tripled in May, and that domestic refineries were continuing production on stockpiled crude. "Adequate supplies of the naphtha ink ingredient have been secured for important functions in Japan," Sato said.
Yet Calbee's monochrome shelves offer a quieter counterpoint to official reassurance — a small, tangible sign that the consequences of distant conflict have a way of reaching into the most ordinary corners of daily life.
Calbee, Japan's largest snack maker, is about to strip the color from one of its most recognizable assets. By the end of May, fourteen of the company's flagship products—many of them potato chips famous for their vivid, eye-catching packaging—will appear on store shelves in black and white. The shift is not a design choice. It is a direct consequence of war in the Middle East.
The culprit is naphtha, a petroleum derivative that forms a critical ingredient in printing ink. When the Iran war erupted in late February and disrupted shipping through the Strait of Hormuz, Japan's access to this material tightened. Japan imports roughly 40 percent of its naphtha from the Middle East, making the blockade an immediate problem for any manufacturer that relies on colored inks. Calbee, which has built its brand identity around vibrant bag designs sold across Asia, Europe, and the United States, found itself forced to choose between waiting for supplies or abandoning the visual language customers have come to expect.
The decision rippled through Japan's business community and media. News of Calbee's monochrome pivot made headlines across the country, arriving just weeks after another snack manufacturer had briefly halted production of a popular crisp brand, citing difficulties securing the heavy oil needed to power its factories. The incidents underscored how thoroughly the Middle East conflict had penetrated Japan's supply chains, even for products as mundane as potato chips.
Calbee itself is no small player. Founded in Hiroshima in 1949 as the city was still rebuilding from atomic devastation, the company has grown into a global snack empire. In 2025 alone, it recorded sales of 322.5 billion yen—roughly $2.04 billion. It owns the British brand Seabrook Crisps, acquired in 2018. The company's stock dipped more than 1 percent on news of the packaging change, though the broader Nikkei 225 Index moved upward overall.
The Japanese government moved quickly to contain the narrative. Kei Sato, a senior government spokesperson, issued a statement—broadcast as an emergency bulletin by some television networks—assuring the public that naphtha shortages would not cascade into wider disruption. Domestic refineries were continuing production using stockpiled crude oil, Sato explained. More significantly, imports from sources outside the Middle East had tripled in May compared with pre-war levels. The government was actively working with major corporations to reroute naphtha shipments away from the Strait of Hormuz entirely.
"Adequate supplies of the naphtha ink ingredient have been secured for important functions in Japan," Sato said. "We have not received any reports of immediate supply disruption for printing ink or naphtha and recognise that Japan as a whole has secured the quantities required."
The statement reflected a broader effort by Japanese policymakers to reassure both the public and the business community that the war's economic fallout would remain contained. Yet Calbee's decision to abandon its signature colors tells a different story—one in which even the largest, most established companies are making visible concessions to geopolitical forces beyond their control. For consumers accustomed to reaching for a brightly packaged bag of Calbee chips, the shift to monochrome will be a small but tangible reminder that the Middle East conflict has consequences that extend far beyond oil prices and shipping routes.

Why does a snack company's packaging matter enough to make headlines?
Because Calbee's colorful bags are how the brand speaks to customers. When you strip that away, you're admitting something has broken in the supply chain. It's not just about aesthetics—it's a visible sign of economic pressure.
But couldn't they just use different inks?
Not easily. Naphtha is a specific petroleum derivative that gives printing inks their properties. There aren't quick substitutes, and Japan relies on the Middle East for 40 percent of what it needs. When the Strait of Hormuz closes, you don't have options.
Is this a temporary fix or permanent?
The government is betting it's temporary. They're stockpiling crude oil domestically and tripling imports from non-Middle Eastern sources. But Calbee's decision to switch by May suggests they don't think supplies will normalize quickly enough to wait.
What does this tell us about Japan's vulnerability?
That even the most successful companies—Calbee made $2 billion in sales last year—can be forced to compromise their core identity by events thousands of miles away. It reveals how dependent Japan remains on Middle Eastern energy, and how little buffer exists when that supply is disrupted.
Are other industries facing similar pressure?
Almost certainly. Another snack maker already had to halt production because it couldn't get heavy oil for its factories. This is likely just the visible tip. Printing, chemicals, plastics—anything that depends on petroleum derivatives is feeling the squeeze.
