Honda said on Thursday (31 March) it would resume production of finished automobiles at its Sayama and Suzuka factories on Monday, 11 April. All production plants in Japan will be in operation as of that date.

Honda also will resume production and shipment of component parts for use in production in regions outside Japan on Monday, 4 April.

But it cautioned that, “as the parts supply situation remains fluid, production of component parts and vehicles at Honda plants will resume at approximately 50% of the original production plan at the outset.”

Nissan said it was “now capable of resuming normal operations at all of our Japanese plants except for the Iwaki engine plant” and aimed “to resume normal operations at these facilities from mid-April”.

“Currently, we have been in production using remaining inventory of supplies. Yet going forward, we will start receiving parts from our suppliers and resume normal operations. However, as the delivery of parts will still take time to be fully reestablished, operation levels will still be limited, depending on the delivery status from suppliers. Nissan will continue to provide necessary support to our suppliers to ensure their swift restoration to normal levels,” the automaker said.

Its Oppama, Tochigi, Kyushu, Nissan Shatai and Nissan Shatai Kyushu plants suspend vehicle production between Monday 4 April and Friday 8 April 8.

At the Yokohama plant and the casting and axle production departments at Tochigi, production will continue during the week of 4 April, manufacturing the necessary powertrain units for the vehicle plants now planned to resume production in mid-April.

Partial operation is planned to resume in mid-April at Iwaki with complete repair targeted for the end of April.

Production of parts for overseas manufacturing and repair parts will continue after 4 April.

“The impact to our production since the earthquake until the end of March is estimated at 55,000 units against original production targets,” Nissan noted.

Mitsubishi Motors operated its Okazaki and Mizushima car assembly plants on Wednesday, 30 March but suspended output at Pajero Manufacturing Company (PMC). All three plants operated on Thursday and will be building vehicles again on Friday.

Mazda on Thursday said it would would resume “limited production” of vehicles at its Hiroshima and Hofu plants from Monday, 4 April, “utilising available parts supply”.

A decision on the resumption of full-scale production of both parts and vehicles would be made later.

Mazda temporarily resumed partial production at its Hiroshima and Hofu plants on Tuesday 22 March, producing replacement parts and parts for overseas production and vehicles utilising “in-process” inventories. On Thursday 24 March it said it would now suspend the production of vehicles using the  “in-process” inventory at Hofu from Monday 28 March.

It also said it would suspend production of replacement parts and parts for overseas production at Hofu after having resumed limited operations there earlier last week.

The Hiroshima factory had been continuing limited production.

Subaru maker Fuji Heavy Industries said it had extended the production suspension of all passenger vehicles (except mini-vehicles) at plants in Japan until Tuesday, 5 Apri, “considering the influence of its suppliers in the affected areas as well as conditions of electric power supply.” Production had been suspended until today, 31 March. 

FHI resumed mini-vehicle production with a limited number of production units today, assessing parts supply as well as electric power supply, but has not yet decided when full-scale output will resume. It restarted production of parts for overseas production on 23 March and production of spare parts on 24 March with some parts available for production.
