Toyota reportedly has halted much production in Japan following an earthquake. It has 18 plants there.

Investor website Seeking Alpha said Toyota made the move following the massive earthquake in the northern island of Hokkaido and resulting power blackout in the region.

A Toyota factory in Tomakomai, which makes transmission and other auto parts, is still without power.

"We have not been able to secure power. We will be flexible on our plant operation as there is no clear visibility," a Toyota Motor spokeswoman told Platt's, adding that there were no plans yet to shift production to other plants outside of Hokkaido.

Other reports said Toyota was, from Saturday (8 September), closing three plants to be followed by other assembly facilities affecting supply of all Lexus and Toyota models in Japan bar a couple of model lines made on an OEM basis by Daihatsu.

Some export models were also likely to be affected, the reports added.

The impact of the Hokkaido earthquake could be felt on the supply chain for months, analysts told Seeking Alpha.

Platt's reported Nippon Steel, Sumitomo Metal, Japan Steel Works and Mitsubishi Steel, all located in Muroran City, had shut down steel mills.
