Toyota Motor suspended production on Tuesday at two of its Japanese factories in a typhoon's path due to concerns that heavy rain and strong wind would affect road conditions and delay parts deliveries.

According to Reuters, over 100 flights had been canceled and evacuation warnings issued for thousands of people as the 'powerful' typhoon approached Japan's northeast on Tuesday, the region devastated by a massive earthquake and tsunami five years ago, with considerable effects to the supply of critical components to automakers worldwide, subsequently resulting in rearrangement of sourcing, and supply chain management, to avoid a repetition.

Typhoon Lionrock had been expected to make landfall in the northeast Tohoku region later on Tuesday, with sustained winds of 120km/h (75mph) and gusts up to 176km/h (109mph) as it moved north from the Pacific Ocean, according to the Japan Meteorological Agency.

Tokyo Electric Power, operator of the Fukushima Daiichi nuclear power plant wrecked in the March 2011 disaster [radiation exclusion zones are still in place - ed], said it had suspended some outdoor operations.

The category one typhoon was expected to dump about 35cm (14 inches) of rain in the northeast by Wednesday morning, more than the average rainfall for all of August, according to Reuters, citing local meteorologists.

However, Lionrock was expected to be downgraded to a tropical storm by the time it made landfall.
