Toyota had been aiming for a high February production plan to meet strong demand.
Toyota's overseas output climbed 5.6 percent to 3.35 million vehicles through June, while production in Japan fell 18 percent to 1.73 million.
Production lines will be switched back on at its 14 factories across the country, Toyota said.
The production upgrades at the Hofu H2 assembly plant in western Japan will underpin upcoming production of new vehicles.
EV production should account for about 40 to 50 percent of Honda's total output in North America in 2030, or around 800,000 battery-electric vehicles.
The automaker will suspend production on three lines at its Motomachi plant in September. That follows suspensions at its Tsutsumi plant.
Toyota is reviewing its production plans as mounting global disruptions hinder its attempts to raise output.
The industry is settling into the new year acknowledging that it's not out of the woods yet on chip shortage disruptions.
