TOKYO — Japan’s vaunted “just in time” approach to business has become “wait and see.” Much of Japan’s industry seemed to remain in a state of suspension Wednesday, as the devastation from an earthquake and tsunami, combined with fear and uncertainty over the nuclear calamity, made it difficult for corporate Japan to think about business as usual.
And that has left many overseas customers and trading partners in something of an information vacuum, unsure how soon the effects of any supply-chain disruptions would make themselves felt — and how long they might last.
Even General Motors, a company that might seem to benefit from disruptions to Japan’s auto industry, finds itself in a period of watchful waiting. For one thing, the new Chevrolet Volt plug-in-hybrid from G.M. — whose sales could conceivably benefit from any production snags in Toyota’s popular made-in-Japan Prius — depends on a transmission from Japan.
Mark L. Reuss, G.M.’s president for North American operations, said Wednesday that he did not yet know whether his company could count on an uninterrupted flow of that Volt component from Japan.
“We just don’t know from a supply standpoint; there’s so many great things that come out of Japan for the whole industry,” he said, speaking to reporters after a speech at the University of Detroit Mercy.
Here in Tokyo, Japan’s business capital, many companies — whether Japanese or foreign — were distracted Wednesday by plans for removing their employees from the potential path of radiation from the damaged Fukushima Daiichi nuclear power plant 140 miles north. Telephone calls and e-mails to many corporate headquarters in Tokyo simply went unanswered.
Air Liquide, a French company that is the world’s biggest producer of industrial gases, has closed its head office in Tokyo and moved its operations 250 miles south to Osaka.
The German auto giant BMW, which has 800 employees in Tokyo, is sending its few dozen German employees home and offering local workers safer locations within Japan.
Even the America unit of the Japanese auto company Nissan has ordered any employees traveling in Japan on business to return home.
Within Japan, Nissan has suspended many of its manufacturing operations at least through the weekend because “it is still taking time to arrange delivery of parts from our suppliers,” the company said in a statement. Nissan’s engine plant in Iwaki, near the coast in the earthquake-stricken region, remained out of action, the company said.
Meanwhile, many American electronics companies remain uncertain — or decline to say — whether supplies of crucial components from Japan will hit air pockets. But Dallas-based Texas Instruments acknowledged that one of its Japanese factories would be at least partially out of action until July and would not resume shipping at full capacity until September.
The plant, in Miho, 40 miles north of Tokyo, suffered extensive damage from the quake. It primarily makes chips that convert analog and digital signals, which are used in a wide range of products, including cellphones, digital televisions, computer peripherals and medical equipment — and accounts for about 10 percent of Texas Instruments global output, by revenue. Kimberly Morgan, a company spokeswoman, declined to name any of the plant’s customers.
Technology analysts say the most persistent worry for digital device makers is the supply from Japan of so-called NAND flash — the lightweight storage chips used in smartphones, tablet computers, digital cameras and a variety of other components. Toshiba, the world’s second-largest maker of the chips behind Samsung of South Korea, has closed some production lines.
SanDisk, the third-largest maker of NAND flash, which owns two factories in Japan jointly with Toshiba, said those factories were operating. But the company, based in Milpitas, Calif., said it was concerned about the reliability of Japan’s transportation and electricity networks.
“It will probably be many days or perhaps many weeks before we can assess the entire situation,” said Mike Wong, a SanDisk spokesman.
The tsunami caused extensive damage to seaports along the northeast coast of Honshu, Japan’s largest island. And while only one — Sendai-Shiogama — ranks among the country’s largest ports, all play a role in receiving goods from abroad and serving as feeders to the nation’s major seaports farther south.
“The situation is quite bad” for the northeastern ports, said Yoshiaki Higuchi, director of planning for the Japan Port and Harbor Association, “but at the moment we aren’t even certain about the extent of the damage.”
A reporter who visited two other small port towns, Minamisanriku and Ofunato, found that the docks and port facilities were almost completely destroyed. In Ofunato, many of the materials that had been stacked on the docks, like lumber, were carried by the waves into the town, where they crashed into homes and added to the destruction, residents said.
