TOKYO -- Flooding in Thailand is cutting Toyota output at Japanese plants that ship some of the company's top-selling exports, including the Prius hybrid, to the United States.
Toyota eliminated overtime at five Japanese assembly plants last week to prepare for a possible shortage of parts from Thailand, where widespread flooding in recent weeks has disrupted the supply chain.
Toyota expected to lose 6,000 units of Japanese output.
Toyota Motor Corp. had been operating the plants with overtime to recoup output lost after the March 11 earthquake.
The slowdown affects plants producing the Toyota Prius, iQ, Land Cruiser, Corolla, Scion tC and RAV4; and the Lexus LS, GS, IS, GX, ES, HS and RX.
Toyota spokesman Dion Corbett said the company did not have a breakdown of how many exports to the United States might be lost. But the number is expected to be small.
The 6,000 units of total lost production represent only around 10 percent of domestic production.
Toyota said it will reassess the overtime schedule for this week.
Flooding in Thailand has paralyzed Japanese automakers operating there.
Toyota, Honda, Nissan, Mazda and Mitsubishi have suspended assembly, either because suppliers' plants or their own factories are inundated by the rising waters.
Toyota's three plants in Thailand have not been damaged by the flooding. But they have been closed since Oct. 10 because of supplier disruption.
Honda's plant in Ayutthaya, with an annual capacity of 240,000 vehicles, has been the worst hit.
Floodwaters inundated the plant on Oct. 8, forcing Honda to evacuate workers and suspend operations indefinitely.
Last week Honda suspended output at a plant in Malaysia because of a shortage of parts from Thailand. Honda said it was also watching for potential impact on other overseas plants.
