Mitsui O.S.K. Lines Ltd., operator of the world's largest merchant fleet, said its car exports may rise from September as Toyota Motor Corp. and other automakers restore production disrupted after the March 11 earthquake.

"The recovery is faster than expected, and should pick up to the same level as last year or even better in September," Chairman Akimitsu Ashida said in an interview Thursday.

The company expects its car shipments may fall 10 percent in July and 15 percent in August as summer vacations and efforts to conserve energy slow auto production, Ashida said.
