Following on the heels of Nissan’s disclosure earlier this week it would be nearly fully operational by mid April, Honda says today it will resume vehicle production at its Sayama, Suzuka and Yokkaichi plants beginning April 11.

Honda produces 0.66L minivehicles in Yokkaichi at a plant operated by subsidiary, Yachiyo Industry Co.

The auto maker advises it will begin operations at about half its original production plan and adjust the build pace in line with the availability of components.

Honda now says it will continue with a reduced production schedule at its North American plants through April 15. And it likely will see fewer builds at those facilities due to parts shortages after April 15, too.

“Given the uncertainty of the parts-supply situation, Honda anticipates additional production disruptions after that date,” the auto maker says in a statement.

Honda reiterates most of the parts for North American-built models are sourced locally and while most of its Japan suppliers are up and running, some are not. Efforts are being made to find additional sources for those suppliers’ components, Honda says.

Honda’s Tochigi technical center, the most damaged of all its Japan facilities and where one worker was killed, will see some of its work, including vehicle development and procurement, temporarily shift to other Honda locations in Sayama, Suzuka and Wako, Japan. Honda believes Tochigi will not be fully functional for several months.

Honda adds it is fully cooperating with the rolling blackouts meant to conserve electricity in Japan.

Elsewhere, Mitsubishi confirms it has been operating its Okazaki, Mizushima and Sakahogi plants for much of this week, though at reduced levels.

“It’s day by day,” says a company spokesman, “and depends on availability of component and material supplies.”

The auto maker’s daily production plan for March had been 2,600 units. Through Friday, March 24, it had lost six days of output, equal to about 15,600 vehicles. The spokesman declines to comment on plant utilization so far this week or to identify components still posing a problem.

However, he says supply chain problems mostly involve Tier 2 and Tier 3 companies.

While Mitsubishi plans to operate all three plants tomorrow no output schedule has been announced for next week.

Meanwhile, Mazda says it will rekindle limited production at its Hofu and Hiroshima plants “utilizing available parts,” but has made no decision on when full-scale output can be reached.

Suzuki, Japan’s leading producer of 0.66L minis, advises today it still is having difficulty procuring components and won’t make a decision about next week’s production plan until tomorrow.

The Hamamatsu-based auto maker plans to run its Kosai and Iwata vehicle plants on a single shift tomorrow and Saturday. It will produce engines, but not cars, at its year-old Sagara facility.

Fuji Heavy Industries (Subaru) is keeping its main Yajima car plant idle until at least April 5. It produces Impreza, Forester, Exiga and Legacy models. The auto maker currently is operating its Ota minicar plant on a limited basis.

Japanese truck maker Isuzu said Monday it planned to gradually resume both vehicle and knockdown component production at its Fujisawa plant beginning April 5. The company will restart engine production tomorrow at its Tochigi facility.

Hino, Toyota’s truck subsidiary, reports today that its Hamura plant, which produces the Land Cruiser Prado and FJ Cruiser for Toyota, will remain idle through Saturday, April 9.

However, Hino will begin limited production at its Hino light-truck operation tomorrow through Tuesday, April 5. No production plan beyond that has been disclosed.

UD Trucks, formerly Nissan Diesel and now a subsidiary of AB Volvo, resumed limited operations Monday, March 28, at its Ageo, Kounosu and Hanyu plants, the latter two making powertrain components.

Also running limited operations this week is Mitsubishi Fuso. The truck maker, which belongs to Germany’s Daimler, reopened its main Kawasaki truck facility March 29.

Toyota and its Daihatsu small-car subsidiary have not updated their production plans from announcements made March 24 and March 28, respectively.

Toyota resumed Prius production at its Tsutsumi plant on Monday, as well as Lexus HS 250h and CT 200h hybrid output at its Miyata factory. All of these assembly lines reportedly are operating at 50% capacity.

Reports Toyota plans to resume non-hybrid operations on April 11 at some or all of its 19 Japanese vehicle plants could not be confirmed.

In addition to the auto maker’s four main factories (Motomachi, Tahara, Takaoka and Tsutsumi), Toyota subsidiaries and affiliates operate 14 assembly plants that account for 65% of annual production.

Included in that number: Central Motor’s 2-month-old Miyagi facility. It suffered extensive damage from the 9.0-magnitude earthquake that struck off of the coast of northeastern Japan on March 11, and reportedly will remain closed for at least a month.

As a result, Central, which had planned to shutter its 50-year-old Sagamihara plant west of Tokyo, will keep that facility up and running for now.
