A limited supply of essential components from Japan has forced Toyota to cut back on car production in the UK.
Last month's earthquake and tsunami in northern Japan affected key suppliers in the country, leading to parts shortages.
The firm is planning to suspend production at its two plants in the UK for several days in April and May.
The shutdowns will take place at the vehicle factory in Burnaston, Derbyshire and the engine plant in Deeside, north Wales.
Production will be stopped there on April 21 and 22, again from 25 to 29, and on May 2, including the long Easter and Royal Wedding bank holidays.
Toyota added that parts supply shortage may persist in May, resulting in a decrease in output volume.
Following consultation with staff representatives and other stakeholders, the company would be able to decide on production volumes and operation.
The car maker said: "This decision is necessary as a result of forecasted parts supply difficulties and at the moment no decision has been made regarding production beyond the month of May."
No decision has yet been made regarding production beyond May. The company said it would continue to evaluate its supply chain and make plans based on the situation.
Tony Walker, deputy managing director of Toyota Motor Manufacturing UK said: "We very much appreciate the strong support of our members in helping us manage this difficult situation."
