McDonald's faces a French fries shortage in Japan

The world's biggest fast food company McDonald's is suffering a chip shortage in Japan due to the global supply chain crisis.

For the home of the Big Mac though it is not a lack of semiconductors that is causing the problem.

The firm has said it is experiencing delays of shipments of the potatoes used to make its famous French fries.

As a result it will only sell small portions of its French fries in Japan from Friday until 30 December.

"McDonald's Japan will temporarily limit sales of Medium- and Large-sized French Fries as a proactive measure to ensure customers can continue to enjoy McDonald's French Fries.

"Customers will still be able to order Small-sized French Fries at all of our restaurants. To date, there have been no breaks in supply," the company told the BBC.
