Toyota has resumed operations at all its plants in Japan after production was halted following the earthquake and tsunami on 11 March.

Volume is still at around 50%, however, due to a shortage of parts.

Toyota has 18 domestic assembly plants, three had already been in operation and the rest resumed production today, the company said.

The carmaker plans to continue with the current capacity until 3 June with production halting during the Golden Week holiday between late April and early May.

The plants that resumed operation on Monday included sites in the disaster-hit Miyagi and Iwate prefectures.

A shortage of components has hit car production in Japan forcing a slowdown overseas as well. Analysts say it could be several months before normal supplies are resumed.

The earthquake and tsunami shattered supply chains and crippled electricity generating facilities.

Many key component manufacturers are based in the worst hit regions of Japan, their facilities damaged in the disaster.
