Japanese food manufacturers are removing colors from product packaging as naphtha supply instability and price hikes impact ink production [1, 2].
This shift toward monochrome packaging for items such as potato chips and ketchup reflects a growing vulnerability in Japan's industrial supply chain. Because naphtha is a primary raw material for printing inks, volatility in the Middle East directly affects the visual branding of consumer goods.
Industry leaders point to geopolitical instability—specifically the potential blockade of the Strait of Hormuz—as the primary driver for the instability [1, 4]. Keiichi Iwata, chairman of the Japan Chemical Industry Association, said that prices for naphtha and crude oil have risen compared to the period before the blockade concerns [1].
While the government maintains that the national supply of necessary materials remains secure [3], some data suggests a broader industrial risk. A survey conducted on April 17, 2024, indicated that 30% of the manufacturing sector is exposed to these risks [5]. Some companies face annual cost burdens of approximately 3 million yen due to these pressures [5].
To mitigate these shortages, the government initiated a second round of petroleum reserve releases on May 1, 2024 [6]. However, the discrepancy between official statements and industry reality remains evident. While government officials said that solvents used in ink are being supplied at normal levels, the Japan Chemical Industry Association noted that supply anxiety is intensifying [1].
Minister of Agriculture, Forestry and Fisheries Norikazu Suzuki said the move to reduce colors is based on the management decisions of individual companies preparing for potential future supply instabilities [1].
“Japan food packaging is turning monochrome as naphtha supply instability and price hikes impact ink production.”
The transition to monochrome packaging serves as a visible indicator of 'cost-push inflation,' where rising raw material costs are absorbed through product design changes rather than direct price increases. The tension between the government's assurance of stability and the industry's proactive downsizing suggests that companies are hedging against a worst-case geopolitical scenario in the Middle East, prioritizing supply chain continuity over brand aesthetics.
