The latest stoppages will bring lost output to 9,000 vehicles, the automaker said, and affect production of Lexus models and the Land Cruiser.
The planned four-day halt to production at a Tsutsumi factory line, which makes Camry and Corolla models, will cut vehicle output by as many as 1,500 vehicles.
The stoppages affect output of Lexus models and the Toyota Land Cruiser as the automaker runs short of components from plants in Southeast Asia where production has been disrupted.
Plants that build the Civic, CR-V, Honda e, Jazz/Fit and HR-V will be affected by output cuts.
Mazda will suspend production at its two domestic factories for two days in April as factors including a rise in COVID-19 cases in China cause supply disruptions.
Toyota said there was "a possibility" that it could lower its full-year production plan of 9.7 million vehicles as it faces a continuing shortage of parts due to the COVID-19 lockdowns in China.
