As the blockade of the Strait of Hormuz chokes off essential raw materials, Japan’s top crisp maker is stripping the colour from its iconic bags to keep production lines running.
Japan’s largest snackmaker, Calbee, is temporarily replacing its brightly coloured packaging with black-and-white designs after supply disruptions linked to the US-Iran conflict, which has led to shortages of key ink ingredients, The Guardian reported.
Known for its vividly packaged potato chips and snacks, the company said 14 of its products will shift to monochrome packaging by the end of May. The move comes as supplies of naphtha, a petroleum-derived raw material used in printing ink, have become unstable following the blockade of the Strait of Hormuz, a vital shipping route for global oil supplies.
Calbee also mentioned that the decision was prompted by the uncertainty in the supply of “certain raw materials” due to the war, as reported by The Guardian.
Manufacturers in Japan impacted
Japan depends heavily on the Middle East for energy imports, with around 40 per cent of the country’s naphtha consumption sourced from the region. The disruption has prompted concerns among manufacturers that rely on petroleum-based materials for packaging, plastics, and chemicals.

The development has drawn significant attention in Japan, where companies are already grappling with rising input costs and supply chain uncertainties. Earlier this year, a temporary halt in production of another popular crisps brand due to difficulties in procuring heavy oil had triggered a brief consumer panic.
‘Adequate supplies of naptha ink ingredient secured’
Responding to concerns, senior government spokesperson Kei Sato said Japan has sufficient reserves and is diversifying import routes to maintain supplies.
“Adequate supplies of the naptha ink ingredient have been secured for important functions in Japan. We are working with major corporations to ensure naptha is imported by routes other than through the Strait of Hormuz,” Sato said in remarks broadcast as an emergency bulletin by some television networks.
“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”, he added, as mentioned in The Guardian.
Founded in Hiroshima in 1949, as the city was rebuilding after the atomic bombing, Calbee has grown into one of the world’s leading snack manufacturers, with products sold across Asia, Europe, and the United States. The company acquired the UK-based Seabrook Crisps in 2018.
Calbee reported sales of 322.5 billion yen (about $2.04 billion) in 2025. Its shares fell more than 1 per cent following the announcement, even as Japan’s benchmark Nikkei 225 closed higher overall.
