Trouble at Japan Inc. as shine is further tarnished by more admissions of malpractice
NOV 24, 2017

Japan’s reputation for manufacturing prowess took another hit this week after Mitsubishi Materials Corp. admitted it faked data on some products just weeks after a similar scandal engulfed Kobe Steel Ltd.

Buyers of Japanese industrial goods from Boeing Co. to Airbus SE were once again scrambling to confirm whether safety had been compromised, after Mitsubishi Materials said three of its units had faked data on products that may have been delivered to more than 250 customers.

Mitsubishi Cable Industries Ltd. falsified data on rubber seals, while Mitsubishi Shindoh Co. misreported the strength of brass strips for auto parts, according to a statement Thursday. The products may have been shipped to 229 Mitsubishi Cable clients and 29 customers of Mitsubishi Shindoh.

Rubber products made by Mitsubishi Cable that did not meet the specification requirements of the Self-Defense Forces were used in some of the engines of their aircraft and vessels, officials at a government agency responsible for development and procurement of defense equipment have said. At Mitsubishi Cable, specification data on its O-ring sealing products were altered to match the requirements specified by client companies.

A third unit, Mitsubishi Aluminum Co. Ltd., also supplied non-conforming products, although it has already confirmed with customers that they are safe, the company said, adding that its investigation has not so far uncovered any cases that raise the possibility of legal violations or safety issues.

The revelation is the latest in a series of scandals to dent the image of Japanese manufacturers, and closely resembles recent admissions by Kobe Steel that it falsified data on the strength and durability of its products. In the auto sector Nissan Motor Co. has said it conducted vehicle inspections that didn’t comply with regulations for almost four decades, while Subaru Corp. allowed uncertified workers to make final safety inspections on vehicles before they were shipped.

And in one of the best known cases, air bag manufacturer Takata Corp. filed for bankruptcy earlier this year due to faulty products.

Mitsubishi Materials closed 8.1 percent lower Friday, wiping almost $400 million from its market value. Its stock had hit a two-year high earlier in the month, buoyed by stronger global metals prices. While the units affected are relatively small, the company said it can’t yet quantify the impact on its earnings.

Mitsubishi Materials President Akira Takeuchi told a briefing in Tokyo on Friday that the company didn’t disclose the problem when it reported earnings earlier this month because it wanted to find all of the customers affected. Takeuchi also said he won’t quit due to the misconduct.

“My duty is to instruct and supervise the investigation of the causes, and to take preventive measures swiftly,” he said.

Takeuchi also said the company is carrying out a probe into all of its operations, including practices at its subsidiaries.

Mitsubishi Cable and Mitsubishi Shindoh said Thursday they have each set up an investigative committee whose members include external lawyers to conduct a detailed probe and compile preventive measures.

Mitsubishi Materials expects the results of its investigation to be released by the end of the year.

At a briefing Friday, trade minister Hiroshige Seko called the matter “extremely regrettable.” He said the ministry has asked related departments to investigate its causes and is seeking an explanation from Mitsubishi Cable on why it took so long to report the problem. He added that he considers it a matter for the companies and not an industry-wide issue.

According to the Thursday statement by Mitsubishi Materials, Mitsubishi Cable uncovered the misconduct in February and stopped shipping non-conforming products on Oct. 23 before the company told its parent firm two days later. Mitsubishi Shindoh found out about its own problem in October and stopped shipments on Oct. 18, alerting Mitsubishi Materials the following day.

Mitsubishi Materials reported on the misconduct, with details of the products and customers affected, to the transport ministry on Friday.

Kobe Steel’s crisis erupted in early October, collapsing its shares. Although 525 customers were affected, none has yet to report safety issues and no products have been recalled. That has allowed its stock to recover some of its losses. As of last week, shipments to 484 clients had been given the all-clear.

Kobe blamed lax controls and too much focus on profit for its shortcomings, including unrealistically high standards that exceeded clients’ expectations and encouraged staff to disregard quality guidelines for a decade or more. The company was forced to abandon its profit forecasts and has lost quality assurance certification — often demanded by customers as a condition of sale — at seven of its 20 plants.

Aircraft maker Airbus SE said in a statement it doesn’t directly procure any materials from the Mitsubishi Materials companies and is investigating whether any of its suppliers are affected. Boeing Co. said it is reviewing the matter.

“Even if Mitsubishi Shindoh and Mitsubishi Cable don’t make up a big portion of the company’s earnings, not just the short-term impact but the mid- and long-term impact on its orders is a cause of concern,” Keiju Kurosaka, senior analyst at Mitsubishi UFJ Morgan Stanley Securities, said in a note.

About a fifth of Mitsubishi Cable’s output of seals from April 2015 to September this year may not meet standards, according to the statement. The company’s seal product business makes up about 40 percent of its revenue. The problems identified at the Shindoh and Aluminum units are much more minor, accounting for less than 1 percent of their sales, according to the company.

報導指出,過去以來三菱電線工業所出產的 O 型環素以高品質,與高可靠性著稱,多數企業將它使用於需要密封的工業零組件當中,例如使用於飛機或核能等產品線上。而目前傳出數據造假的三菱電線工業所出產 O 型環產品,已經被數百個用戶用於其產品上。只是,報導引用多個消息來源指出,截至目前為止尚未發現有安全顧慮的問題。

至於,三菱電線工業因為在 23 日為日本國定休假日,因此公司尚未對此提出正式的說明。

報導進一步指出,三菱電線工業的數據造假案,是因為該公司內部在調查日本第三大鋼鐵製造商神戶製鋼(Kobe Steel)之前發生數據偽造醜聞後意外發現的,三菱材料與神戶製鋼在銅管合資企業中分別各占有 45% 的股權。而 2017 年以來,包括日產汽車、神戶製鋼等日本大企業皆蘭爆出造價醜聞,加上過去幾年來日本企業假造數據的情況屢見不鮮,也使得日本製造高品質產品的形象受到嚴重衝擊。
