These keiretsu are more pyramid-shaped, with a single industry or company at the pinnacle of the pyramid and the member companies collected beneath. Finally, the Japanese believe in what they call "bottom round" management.
In fact, JIT has often been defined as the elimination of waste. It is also referred to as a "pull" system since the authority to produce or supply comes from downstream operations. Skill diversification — multi-functional workers. The timing could not have been worse.

Lot sizes of one — the ultimate lot size and flexibility. The relationships can be even more confusing when one takes into account that some companies bear the name Sumitomo that are not members of the central twenty Sumitomo keiretsu members. Many people mistakenly attribute this phenomenon strictly to cultural differences.
To reduce the risk of the very kind of disruption it was now confronting, Toyota had increased parallel sourcing.
Although a coordinating role may be given to the head of the central bank around which the keiretsu is formed, there is no central president in a classical keiretsu. Even a sewing machine manufacturer was persuaded to help provide valves for Toyota. It is controlling quality at the source.
A challenge for many firms was to ensure close collaboration among usually remotely related units. Taiho met with thirty of its suppliers the day after the fire to plan an appropriate division of labor, eventually involving eleven suppliers in the effort, with Taiho itself taking charge of the final processes.
Rather than a carefully nurtured atmosphere of trust and common enterprise, they see a restrictive system of internal controls. Simplify, and goods will flow like water.
Preventive maintenance — flawless running, no defects. The cooperation of these suppliers was crucial to the success of the recovery effort; undoubtedly, many were hoping to increase sales to Toyota in the future.
Cellular manufacturing — production methods for flow. Aisin was the sole supplier of proportioning valves, a brake-related part used in all Toyota vehicles. Because Toyota and Aisin operated In a just-in-time environment, only a small supply of stock was on hand, and a costly shutdown of.
The Aisin Seiki Co., Ltd. Anjo Plant, Noboribetsu Branch resumed operation on September 8. In addition, Aisin Hokkaido Co., Ltd. and CVTEC Hokkaido Co., Ltd.

The Japanese have had phenomenal impact on world markets.
Many industries, such as electronics, cameras, watches, motorcycles, machine tools, automotive products, shipbuilding, and even some aspects of aerospace are either dominated by Japanese firms or are heavily impacted by them.
Aisin Seiki, whose plants in Kumamoto sustained damage from the quake, said it would make the parts produced in the quake-hit city in other facilities at home and abroad. The parts include sun roofs, door handles, semiconductors, and other products.
Aisin Seiki and Toyota’s effectiveness in handling the consequences of fire is sometimes attributed to their ability to temporarily diversify production and .Impact of jit in aisin seiki
