History

Mitsui Main Building and Nihonbashi Mitsui Tower
Founded by
Mitsui Takatoshi (1622–1694), who was born a fourth son of a shopkeeper in
Matsusaka, called
Echigoya (越後屋) in today's
Mie prefecture. His father originally sold
miso, a fermented soybean paste, and ran a
pawn shop. Later, the family would open a second shop in
Edo (now called
Tokyo).
Takatoshi moved to
Edo when he was 14 years old, and later his older brother joined him. Ever since he was very young, he had shown outstanding business talent. But because of that, his jealous brother sent him back to Mie when he was 28 years old. He waited for 24 years until his older brother died before he could take over Echigoya. He opened a new branch in 1673; a large
gofukuya (
kimono shop) in
Nihonbashi, a district in the heart of Edo. This genesis of Mitsui's business history began in the
Enpō era, which was a
nengō meaning "Prolonged Wealth".
In time, the gofukuya division separated from Mitsui, and is now called
Mitsukoshi. Traditionally, gofukuyas provided products made to order; a visit was made to the customer's house (typically a person of high social class or who was successful in business), an order taken, then fulfilled. The system of accountancy was called "margin transaction". Mitsui changed this by producing products first, then selling them directly at his shop for cash. At the time, this was an unfamiliar mode of operation in Japan. Even as the shop began providing dry goods to the government of the city of Edo, cash sales were not yet a widespread business practice.
At about this time, Edo's government had struck a business deal with
Osaka. Osaka would sell crops and other material to pay its land tax. The money was then sent to Edo—but moving money was dangerous in middle
feudal Japan. In 1683, the shogunate granted permission for
money exchanges (
ryōgaeten) to be established in Edo. The Mitsui "exchange shops" facilitated transfers and mitigated that known risk.
On
July 1,
1876, Mitsui Bank, Japan's first private bank, was founded with
Takashi Masuda (1848–1938) serving as president. Mitsui Bank, which following a merger with Taiyō-Kobe Bank in the mid 1980s became part of
Sakura Bank, survives as part of the
Sumitomo Mitsui Banking Corporation). During the early 20th century, Mitsui was one of the largest
zaibatsu, operating in numerous fields.
After the end of the
Second World War and the dissolution of the zaibatsu, Mitsui lagged somewhat behind its rival Mitsubishi Group and Sumitomo Group in reorganization. Mitsui Bank, which should have been the mainstay and principal capital provider of the group, declined in size due to the collapse of the
Imperial Bank of Japan, which resulted in reduced cohesion of the conglomerate. Many companies that were once part of the Mitsui Group have become independent or tied to other conglomerates. Specifically,
Toshiba,
Toyota Motors, and
Suntory, once part of the Mitsui Group, became independent, with the Toyota Group becoming a conglomerate in its own right. Ishikawajima-Harima Heavy Industries is now considered to be part of the
Mizuho Group, and many companies in the
Mitsui-Sumitomo Financial Group are now more closely tied to the
Sumitomo Group than the Mitsui Group. Recently there have been signs that
Mitsubishi UFJ Financial Group and the
Mitsubishi Group could be taking over other parts of the Mitsui-Sumitomo Financial Group. Mitsukoshi merged into
Isetan, a major department store with a close tie to the
Bank of Tokyo-Mitsubishi UFJ, to form Isetan Mitsukoshi Holdings in April 2008.
