Supply Shock: Japan’s Rice Shortage Shakes Tradition

Japan is bringing in rice from South Korea for the first time in more than 25 years as domestic shortages hit supply chains and push consumer prices to record highs.

For a country known for its protectionist rice policies and a population that has long eyed foreign grain with suspicion, this marks a notable change in both trade dynamics and eating habits.

South Korean rice began arriving in Japan last month, the first shipment since 1999, with a modest initial import of two tonnes. Public broadcaster NHK says another 20 tonnes are on the way.

Although the quantity is small, the decision signals growing demand as domestic prices continue to rise despite government efforts.

The average price for a 5kg bag of rice hit ¥4,214 (US$30) in early April - more than double the price from the same time last year.

The surge began with poor harvests in 2023 caused by extreme summer heat, followed by panic buying triggered by typhoon and earthquake warnings. These events drained national stockpiles and prompted retailers to impose limits on purchases.

The government responded by releasing 210,000 tonnes from its rice reserves in March, a move usually reserved for disasters or crop failures.

However, this time, the problem wasn’t a poor harvest, it was getting the grain to shops. Logistical issues slowed the process as, by the end of March, only 426 tonnes (just 0.3%) had reached supermarkets.

The Ministry of Agriculture blamed a shortage of delivery vehicles and time-consuming preparation of the grain for sale.

Supply chain bottlenecks, rather than poor yield alone, are now Japan’s biggest obstacle in feeding its population.

Restaurants and consumers adjust to foreign options

Imported rice is no longer taboo for many diners, with some restaurant owners having already switched to American-grown rice last year when domestic prices began to climb. Though the price of the Californian rice has since doubled, it remains more affordable than Japanese rice.

Even as demand rises, domestic farmers are finding it difficult to increase output. Government policies aimed at limiting production to stabilise prices mean many fields are allocated to rice used for processed food or animal feed. These subsidies have shaped Japan’s agricultural output for years.

One farmer, Mori Michihiro in Kushima City, Miyazaki Prefecture, used to dedicate 10% of his land to rice not meant for tables. Now he grows only table rice but says rising costs of fuel and equipment mean profit margins are tight.

This production cap is part of what Kazuhito Yamashita from the Canon Institute for Global Studies believes has led to the crisis.

He says the shortage "could have been foreseen" and argues that relying on emergency stockpile releases is a short-term fix.

"The demand for imported rice is very high and even customers who have never bought it before are asking about it," adds Ryo Asakawa of Kanematsu’s Grain Department, which imported 10,000 tonnes of Calrose in February.

"We have enquiries every day. As long as there is demand from our customers, we will continue to supply it."

What can supply chains do to mitigate these risks? 

Japan’s rice supply chain is under pressure from a mix of weather-related crop failures, rising prices and broken distribution links. To restore resilience, long-term structural reforms are needed.

One approach is to enhance supply chain transparency. Introducing digital record-keeping and blockchain technologies can allow rice to be traced from field to retailer. This offers a clear view of where problems such as bottlenecks or contamination might occur. These tools also support better stock management and real-time monitoring, helping move rice faster from warehouse to supermarket shelf.

Aligning efforts between government bodies, distributors, cooperatives and private firms makes it easier to act quickly when disruption hits. Tapping into the expertise of researchers and technology firms also ensures the system continues to adapt.

As Japan looks ahead, a more resilient supply chain means better food security and fewer price shocks for its most essential staple.
