Nissan plans to resume auto and parts production at more Japanese factories next week, but it may be months before inventories and other elements of the country’s auto industry return to normal.

Nissan said it will resume production of parts at five plants today. It then plans to resume vehicle production Thursday as long as supplies last.

Most of Japan’s auto industry shut down after the powerful earthquake and tsunami devastated the country earlier this month. Nissan and other carmakers have started resuming some production, but the industry still faces rolling blackouts and infrastructure problems.

Supply levels probably won’t return to normal until mid to late summer, said Michael Robinet, director of global production forecasting for IHS Automotive.

Honda has said it will suspend production until Wednesday. More than 100 of its suppliers are based in the area near where the earthquake and tsunami hit.

Toyota has shut its assembly plants through at least Tuesday. Mazda also said it would resume temporary production Tuesday at a couple plants.
