ployer still would not have below him the extensive enterprise sector of medium and smaller subcontractors that his Japanese counterpart can squeeze in difficult times. Tomioka calls the subcontractors the "shock absorbers" of the Japanese business cyclethe smaller firms on the receiving end when large firms find they can no longer carry the fixed costs of their labor force and must "shift the strain" (
shiwayose
).

On the other hand, the American employee would not have Japan's extensive if redundant distribution system to fall back on in case he did get laid off. The distribution system in Japan serves as a vast sponge for the unemployed or underemployed when economic conditions require it. As testimony to the layers of middlemen in Japan, the volume of transactions among Japanese wholesalers in 1968 exceeded the total of retail sales by a ratio of 4.8 to 1, whereas the United States figure was 1.3 to 1.

It is not surprising that many knowledgeable Japanese do not want to change the distribution system, despite protests from foreign salesmen who have trouble breaking into it, because it performs other functions for the society than distribution, not the least of which is reducing the tax burden necessary to provide adequate unemployment insurance.
Lifetime employment, Japanese style, offers many advantages from the point of view of economic growth: it provides a strong incentive to the employer to operate at full or close to full capacity; it inhibits a horizontally structured trade union movement; and, in the words of Ohkawa and Rosovsky, it gives the Japanese entrepreneur "a labor force without incentives to oppose technological and organizational progress even of the labor-saving type."

But it does not exist in isolation and would not work without the rest of the system of "unique institutions."
The second main point about these special institutions concerns the date of their origins and how they are maintained. It is here that this school of explanations of the miracle sometimes blends imperceptibly with the first school, which says that Japanese culture and the Japanese national character support the economy. Amaya, for example, traces the three sacred treasures to the traditional world of family (
ie
), village (
mura
), and province (
kuni
), which he believes have all been homogenized and reincarnated today within the industrial enterprise.

It has to be stated that assertions of this type are a form of propaganda to defend these special institutions from hostile (often foreign) critics. Extensive research by scholars in Japan and abroad has demonstrated that virtually all of the so-called special institutions date from the twentieth century and usually from no earlier than the World War I era.
