The sweeping shutdowns, which begin in August and run through the end of September, will hammer Toyota output in every major market -- Japan, the U.S., Europe, China and Asia.
Toyota had been aiming for a high February production plan to meet strong demand.
The automaker said parts such as semiconductors and wire harnesses are in short supply because of bottlenecks triggered by lockdowns in southeast Asia.
The automaker will reduce output again in November, but the impact will not be as painful as before and Toyota sees signs of recovery on the horizon.
The automaker has asked suppliers to make up for lost output so it can build an additional 97,000 vehicles between December and the end of March, Reuters reported.
The comment comes after the automaker said a parts shortages would cost it 14,000 vehicles in lost production in December.
Toyota said it would slash its global production plan for April by 150,000 units to 750,000 vehicles, compared with the original schedule reported to suppliers earlier this year.
The automaker this month will suspend output at all but one plant in North America — putting more pressure on dealers with historically low inventories.
For 2022, the IHS Markit light-vehicle production forecast was cut by 9.3 percent, or about 8.4 million vehicles.
Toyota could lose up to 480,000 units from January through March.
Plant shutdowns have translated into lost wages for tens of thousands of workers across Mexico due to furloughs and layoffs.
Even the best supply chain planning is proving no match for a pandemic that virtually ground the auto industry to a halt a year ago and has plagued efforts to restore production.
The industry is settling into the new year acknowledging that it's not out of the woods yet on chip shortage disruptions.
