TOKYO — Toyota Motor Corp. on Friday said it would reduce vehicle production in Japan by 122,000 units in June, as a lack of demand for new cars due to the coronavirus prompts the automaker to keep its plants running on limited operations.

The drop in Toyota’s production underscores the challenging conditions for carmakers around the world due to the fallout from the virus. Besides weak demand, problems with procurement and social distancing measures at plants are also expected to hit output.

The automaker said it would halt production at all of its 15 plants for four days next month, while stopping output for up to 7 days on 10 of its production lines, which make models including the Prius gasoline hybrid, Corolla sedan, and 4Runner midsize SUV.

In addition, it plans to operate only single shifts on five production lines next month, an arrangement which would continue on two lines through July, and through August on another, it said in a statement.

A Toyota spokeswoman said the reduced output represented a 40 percent cut from initial plans made earlier in the year, while declining to give further details. In June 2019, it produced 289,544 vehicles at home.

Earlier this week, Reuters reported that Toyota planned to slash production in North America by nearly a third through October due to the coronavirus The automaker resumed some output at its seven North American sites this week.

Toyota is bracing for an 80 percent drop in full-year operating profit, its lowest in nine years, as it expect car sales to remain weak for much of the year.

Some analysts believe industrywide global auto sales could slump by a third this year and that any recovery will be slow and patchy as job losses and reduced incomes weigh on consumer spending.
