Effects of the Collision and Decomposition of Japanese Business Groups on Group Collapse

Sung-Baig Choi


According to the credit-rating agency in Japan, Tokyo Shoko Research, the sales of 27 affiliates of Mitsubishi Group amount to 410 trillion yen, and the number of related companies is as large as 40,000. This is comparable to the total number of companies in Singapore or Finland. The total sales of companies in Japan amount to 1,625 trillion yen, among which, the 3 major groups (Mitsubishi, Mitsui, Sumitomo) account for 60 percent (961 trillion yen). This implies that a number of companies in Japan deal with these 3 major groups in whatever form it may be.
Business groups in Japan have taken lead of the economic growth of Japan as strong stockholders that maintain close unity and mutual cooperation. Recently, however, their unity seems to be weakened, which is expected to affect Japanese companies’ competitiveness in any form.
