The keiretsu system
was a recurring theme in the trade squabbles that occurred between the
United States and Japan in the late 1980s and early 1990s. According to
the U.S. view, the keiretsu system tilted the playing field of the
Japanese marketplace against outside competitors. The keiretsu issue was a
centerpiece of the U.S. government’s Structural Impediments Initiative (SII)
of March 1990—a bill designed to pry open the Japanese marketplace.
"A
Series of Affiliations"
At the simplest
level, the Japanese word keiretsu simply means “a series of
affiliations.” In this strict sense of the word, there are many “keiretsu”
in the United States. For example,
automotive parts manufacturer Delphi Corporation was originally a wholly
owned subsidiary of General Motors, and still maintains links to GM as an
independent company. The publishing and media world is full of keiretsu as
well;
publishing giants like Random House own dozens of smaller imprints and
publishers.
How are the Japanese
keiretsu unique and different? According to the critics of the keiretsu
system, each of Japan’s “series of affiliations” effectively functions as
a giant mega-firm, excluding outsiders and restricting competition in the
marketplace.
T. Boone Pickens was
one of the first Americans to expose the keiretsu system to public
scrutiny. In 1990 the Texas oilman and corporate raider became the largest
stockholder of Koito Manufacturing Company---an automotive components
manufacturer in Toyota Motor Company’s keiretsu system. Pickens was
disgruntled over two points. First of all, he believed that Toyota,
Koito’s second largest shareholder, manipulated Koito into pricing its
automotive components at artificially low levels, thereby hurting Koito’s
shareholders. He was also miffed because Koito would not give him a seat
on its board of directors.

The Vertical
Keiretsu
Toyota Motor Company
is a classic example of a vertical keiretsu---one of the two major
varieties. A vertical keiretsu is a group of companies that exist for the
benefit of a single, monolithic manufacturer.
As one might expect,
there is also a Honda keiretsu; and most of Japan’s large manufacturing
firms maintain some sort of keiretsu network. A vertical keiretsu consists
of tiers, with a company like Toyota at the top, followed by a secondary
tier of major suppliers, and then a tertiary tier of smaller
manufacturers. Although their primary raison d'être is manufacturing,
vertical keiretsu also include trading companies and financial service
providers.
There are exceptions
to the rule, but suppliers within a given vertical keiretsu generally
don’t do business with the lead company’s competitors. A supplier in the
Toyota network would restrict sales of its components to Honda, for
example.
The lead company is often a major stockholder in
the keiretsu member companies. In many cases, the lead company also
dispatches top managers to work in the keiretsu firms. Early in my career,
I worked for a Honda keiretsu company in Ohio. Two of the company’s
executive vice presidents were dispatch employees from Honda.
