Japan’s McDonald’s has joined the unfortunate ranks of Toyota, Sony and other industrial giants that have become victims of the chip supply crisis.

The fast food group said on Tuesday that due to delays in deliveries from Canada, it can only provide a minimum amount of French fries in its 2,900 branches.

A company spokesperson said that an emergency plan has been launched to ensure “continuous supply of French fries to customers.”

He said that medium and large portions will be reduced, and customers will be offered small discounts on meal prices, adding that French fries shipped by air have already begun to arrive in Japan.

The supply of hash browns that appeared on the breakfast menu did not appear to be affected by the interruption in delivery.

McDonald’s stated that the ration of French fries will begin on December 24 and is expected to end on December 30. The shortage occurred during the holiday season traditionally dominated by rival KFC.

Japanese consumers have been ordering for nearly half a century KFC Christmas Chicken Thanks to the advertising campaign for successfully linking fast food chains to the holidays. KFC uses a family bucket reservation system to ensure that it meets the poultry frying boom on December 25.

In order to oust KFC from its position on Christmas Eve, McDonald’s is launching a seasonal event that focuses on cheap supply of chicken nuggets. This ad was made before the announcement on Tuesday and showed a family enjoying gold nuggets and the largest serving of French fries.

Japan is one of the fast food company’s largest markets outside the United States.

The chip problem is a combined result of the Covid-19 pandemic and the serious backlog in the port of Vancouver after recent floods and landslides destroyed the highway.

The blockade has exacerbated the turbulence in the supply chain caused by the pandemic cargo boom and port congestion, which has greatly increased freight costs.

Burger King said it has no plans to change French fries sales. KFC could not be reached immediately for comment.

Before the pandemic, the fragility of the Japanese potato supply chain was an issue. In 2017, the weak autumn potato harvest on the northern island of Hokkaido in Japan led to a shortage of potato chips. In some cases, consumers were hoarding their favorite snacks about to be out of stock.
