The History of the Mitsubishi Group

The Founder

Iwasaki Yataro
(1835-1885)

An ambitious young man named Yataro Iwasaki launched the first Mitsubishi company--a shipping firm--in 1870. Japan had just emerged from centuries of feudal isolation and was racing to catch up with the West. Yataro's business grew rapidly and diversified into a broad range of manufacturing and commerce. World War II brought an end to Mitsubishi as an integrated organization. But independent companies that trace their roots to the old Mitsubishi are active today in nearly every sector of industry.

Yataro Iwasaki was from the city of Kochi on the island of Shikoku, which was the home of the powerful Tosa clan. He worked for the clan and distinguished himself in managing its Osaka trading operations. In 1870, he set up his own shipping company, Tsukumo Shokai, with three steamships chartered from the clan. That was the beginning of Mitsubishi.

Origins of the Famous Emblem

Three Tosa leaves join three stacked rhombuses to become three red jewels.

The name of the new company changed to Mitsukawa Shokai in 1872 and to Mitsubishi Shokai in 1874. Yataro chose a corporate emblem that combined the three oak leaves of the Tosa crest and the three stacked diamonds of his family crest. That emblem is the source of the name, Mitsubishi, which means "three diamonds."

Yataro made a public display of patriotism in 1874, providing ships to carry Japanese troops to Taiwan. That earned the gratitude of the government, which rewarded him with 30 vessels. Yataro changed his company's name to Mitsubishi Mail Steamship in 1875, when it inherited the employees and facilities of a mail service disbanded by the government.

"Mitsubishi" and the Famous Three-Diamond Mark

The name "Mitsubishi" refers to the three-diamond emblem. "Mitsubishi" is a combination of the words mitsu and hishi. Mitsu means three. Hishi means water chestnut, and Japanese have used the word for a long time to denote a rhombus or diamond shape. Japanese often bend the "h" sound to a "b" sound when it occurs in the middle of a word. So they pronounce the combination of mitsu and hishi as mitsubishi.

Yataro Iwasaki, the founder of the old Mitsubishi organization, chose the three-diamond mark as the emblem for his company. The mark is suggestive of the three-leaf crest of the Tosa Clan, Yataro's first employer, and also of the three stacked rhombuses of the Iwasaki family crest.

A perennial subject for speculation is why Yataro chose not to put his own family name on his new company. If he had, we now might speak of Iwasaki Heavy Industries, Iwasaki Electric, and Bank of Tokyo-Iwasaki. But he opted for a different name.

Whatever Yataro's reason for refraining from using the Iwasaki name, it surely wasn't modesty. Yataro was a bold and aggressive leader. Still, he might have felt some deference toward the Tosa Clan. Support from the clan was instrumental in launching his inaugural venture in shipping. And putting his own name on that venture might have seemed overly impudent, even to Yataro Iwasaki.

Rapid Growth. Then Adversity

Mitsubishi Mail Steamship inaugurated service to China and Russia and enjoyed a virtual monopoly on overseas routes. But the political winds shifted against Mitsubishi in the early 1880s, and the government sponsored the establishment of a competitor. The ensuing competition nearly bankrupted both companies.

Government intervention produced a temporary truce. But cutthroat competition resumed when Yataro died in 1885 and was succeeded by his brother Yanosuke. The feud ended with a government-arbitrated merger in 1885, which created Nippon Yusen--today's NYK Line.

Beyond Shipping

While competition was escalating on the sea, Mitsubishi was diversifying ashore. The company purchased the Yoshioka copper mine in Akita and Takashima coal mine in Nagasaki. It leased the Nagasaki Shipbuilding Yard from the government in 1884 and later engineered Japan's first domestically produced steel steamship there.

Mitsubishi continued to grow and diversify under the autocratic leadership of Yanosuke Iwasaki. He bought up more mines to provide resources for Mitsubishi and Japan's growing industries. And he dropped "Steamship" from the company name. He also paid the equivalent of approximately US$1 million for 80 acres of swampy marsh next to the Imperial Palace in 1890. Ridiculed at the time, Yanosuke's investment today is worth many billions of dollars.

Modern Management

Yataro's son, Hisaya, assumed the presidency in 1893. The University of Pennsylvania graduate restructured Mitsubishi to support increasingly diverse business operations. He set up divisions for banking, real estate, marketing, and administration, as well as for the original mining and shipbuilding businesses.

Some of Hisaya's private investments are part of today's Mitsubishi companies. He purchased the Kobe Paper Mill, which is today's Mitsubishi Paper Mills. And he backed the founding of Kirin Brewery. His cousin Toshiya founded Asahi Glass, Japan's first successful manufacturer of plate glass.

Mitsubishi management modernized further when Yanosuke's son Koyata succeeded Hisaya as president in 1916. Koyata, a graduate of Cambridge University, incorporated the divisions as semiautonomous companies. He steered Mitsubishi to leadership in such sectors as machinery, electrical equipment, and chemicals. The companies that later became Mitsubishi Heavy Industries developed automobiles, aircraft, tanks, and buses. And Mitsubishi Electric became a leader in electrical machinery and in home appliances.

Beyond the Family

The Iwasaki family relinquished some of its control over Mitsubishi through a public offering of shares in the core holding company. By the end of World War II, outside investors held more than one-half of the equity.

Koyata Iwasaki encouraged his managers and employees to stand above the xenophobia that swept Japan during the war years. "We count many British and Americans among our business partners," he reminded Mitsubishi executives shortly after the outbreak of hostilities. "They are our friends who have undertaken projects together with us and who have shared interests with us. Should peace come again, they should again become good and faithful friends."

Separate Paths

After the war, the allied occupation forces demanded that Japan's big industrial groups disband. Mitsubishi Headquarters disbanded on September 30, 1946, and many of the Mitsubishi companies split into smaller enterprises. The trading arm fragmented into 139 companies. Mitsubishi Heavy Industries became three regional companies. Most of the Mitsubishi companies abandoned the name and emblem under pressure from the occupation forces.

On the outbreak of the Korean War, the occupation policy shifted to an emphasis on industrial and economic reconstruction. Some of the Mitsubishi companies reconstituted themselves, and most began using the name and emblem again. But they retained their autonomy. The companies achieved far more individually and independently than they ever could have accomplished as a single organization. At the same time, they benefit from the shared sense of community that accrues from a common history and corporate culture.

Mitsubishi Electric Genealogy

Mitsubishi Electric Corporation was founded in 1921 when Mitsubishi Shipbuilding Co. (currently Mitsubishi Heavy Industries, Ltd.) spun off its marine electric motor factory in Kobe.

Subsequently, Mitsubishi Electric firmly established itself as a diversified electric equipment manufacturer, branching into nearly every sector related to electric equipment.
