Keiretsu are a modern-day, looser version of the Japanese zaibatsu, which flourished from the 1920s to
1945, and of which 16 were formally dismantled and outlawed in 1946-1947 by U.S. occupation
authorities (Caves and Uekusa 1976). Zaibatsu and keiretsu
30
can be described as conglomerates
31
with
important horizontal and vertical relationships that may be informal, contractual, or reinforced by
cross ownership; they may be united by a holding company that controls a major bank.
32
Many
zaibatsu were revived or tolerated by the authorities in the 1950s in order to supply the allies in the
Korean War. Several keiretsu were newly formed or first began growing rapidly at this time.
33
Cracks in the keiretsu system serving the automotive sector first began around 1999 when Renault
took over struggling Nissan (Dawson and Kendall 2013). In June 1999, the Renault-Nissan Alliance
appointed a new hard-charging CEO, Carlos Ghosn, who emphasized extreme cost-cutting
measures as a principal strategy to improve profitability.
34
Nissan’s keiretsu was disbanded and
replaced by open-source bidding for Nissan parts and components. In order to stay price-
competitive, Toyota and Honda shifted to open bidding too, initially outside of Japan. Collusion in
four Japanese auto-parts cartels began in the year 2000.
The second blow to the keiretsu system occurred in 2005 when the Japanese Fair Trade Commission
instituted a formal corporate leniency program for cartelists (JFTC 2005). This program, modeled on
programs adopted by other antitrust authorities as early as 1993, offered powerful monetary
incentives for cartel participants to confess their own transgressions, denounce fellow conspirators,
and normally cause the collapse of the cartel. “[Japanese] companies fingered in other cartels
worried they’d be burned again if they didn’t step forward,” said Kazuhiko Takeshima, former head
of the JFTC (ibid.). The leniency program was contrary to widely held notions of oligopolistic
cooperation among leading Japanese businesses, especially keiretsu members. In January 2009, the
JFTC and three other antitrust authorities opened investigations into price fixing of
undersea/underground cables; two of the suspects were Furukawa Electric and Sumitomo Electric.
30
The major difference between the two seems to be that zaibatsu were controlled by and named after extended families
(Mitsui, Mitsubishi, Sumitomo, etc.), whose assets were seized in 1946, whereas keiretsu are organized by a single final-
product manufacturer or manufacturing group. Additionally, the former tended to emphasize tight vertical integration by
a single supplier, whereas the latter accommodated a small number of suppliers that had a degree of rivalry in R&D.
31
Besides a big bank, holding company, and international wholesale trading firm, each Keiretsu usually includes insurance,
shipping, and a wide variety of manufacturing companies.
32
For example, the Tokai (or Toyoda) Group is led by the Tokai Bank and includes the Daihatsu, Suzuki, and Toyota
auto manufacturers. Toyota sponsors a supplier group known as Kyohokai that encompasses 200 parts suppliers (Jie et
al. 2013). While ostensibly an information-sharing organization, meetings and outings offer opportunities for collusion.
After being convicted for price fixing of wiring harnesses and related safety equipment in 2011, Fujikura Ltd., after
strengthening its internal antitrust compliance program, withdrew from Kyohokai activities. The major change from the
1920s is that family control has been replaced by holding-company shareholder control.
33
Toyota and Honda are examples. Toyota Group owns in Toyota Motor Corp., and TMC has majority or controlling
shares in auto-parts suppliers Denso Corp., JTEKT Corp., Tokai Rika Co., Kanto Auto Works, Aichi Steel Corp, Aisin
Seiki Co., Ltd and others. Toyota’s bank was known as Toyo Trust and Banking until 2001 when it merged with two
other banks to become UFJ Bank (now Mitsubishi UFJ Financial Group, Inc.). As of early 2013, Denso and Tokai Rika
Co. were convicted and JTEKT was a suspect in bid rigging. Honda owns 15% of Yamashita Rubber Co., a defendant in
the Rubber Anti-Vibration Parts cartel.

Carlos Ghosn was initially appointed COO of Nissan Motors by Renault in June 1999 and became CEO and
President of Renault in 2005. In the late 1900s he earned the sobriquet “Le Cost Killer” after restoring Renault to
profitability through plant closings and other cost-cutting measures. He is co-author of the book Shift: Inside Nissan's
Historic Revival (http://uk.askmen.com/celebs/men/business_politics_60/76_carlos_ghosn.html). In October 2016,
Mitsubishi Motors joined the Renault-Nissan Alliance. In 2019, Mr. Ghosn was arrested and imprisoned in Japan for tax
evasion.
