keiretsu

Imagine a web of connected businesses. That's a keiretsu. It is a Japanese term for a group of companies tied together through business relationships, shared ownership, banking links, and regular trade with one another. These are not just casual partnerships. They became especially important in Japan after World War II and helped support long-term growth and stability. You might hear this word when people talk about Japanese business, industry, or the way large companies work together over many years.

A keiretsu (pronounced kay-ret-soo) is a specific type of business group historically prominent in Japan. It's more than just a collection of companies; it's a complex network built on cross-shareholding, mutual trading preferences, and often, shared banks. These groups formed largely after World War II as a way to rebuild the Japanese economy, providing stability and long-term investment where traditional financing was scarce.

There are two main types: horizontal keiretsu, which consist of companies in diverse industries (like Mitsubishi or Sumitomo), and vertical keiretsu, centered around a large manufacturer with suppliers and distributors linked to it. These relationships aren't always formal contracts; they're often based on trust, tradition, and long-standing business ties.

Historically, keiretsu were criticized for potentially stifling competition, but proponents argue they fostered innovation through collaboration and provided a stable foundation for economic growth. While their influence has lessened in recent years due to globalization and regulatory changes, keiretsu still play a significant role in the Japanese business landscape.

You might encounter this term when reading about Japanese economics, international trade, or corporate governance. Understanding keiretsu provides insight into Japan's unique approach to capitalism and its emphasis on long-term relationships over short-term profits. For example, "Toyota is a key member of the Toyota Group keiretsu, benefiting from close ties with its suppliers." Or, "The restructuring of Japanese industry in the 1990s saw some keiretsu loosen their grip on affiliated companies."
