Yoko Kubota:

Toyota Motor Corp. is preparing to reorganize the company around product classes in a shift from a regional orientation after topping global sales of more than 10 million vehicles in each of the past two years.

Toyota will outline the changes before its fiscal year ends in March. The plan, said people familiar with the situation, is to make the car maker more nimble in the face of challenges due to its sheer size.

President Akio Toyoda wants to reorganize the company into units focused on vehicle size and type, according to one of the people familiar with the matter. One unit might be in charge of Toyota’s compact-car business, while another might handle sedans. Other units could focus on commercial vehicles or additional business segments.

Toyota spokesman Ryo Sakai declined to comment.
