財閥

Zaibatsu sounds antique, but the system it named was aggressively modern. The word 財閥, literally a financial clique or wealth faction, took shape in Meiji Japan as industrialization concentrated banking, mining, shipping, and manufacturing in giant family-controlled combines such as Mitsui, Mitsubishi, Sumitomo, and Yasuda. This was not free-market folklore. It was organized concentration.

The form joined 財, wealth or finance, with 閥, a clique or faction. The second element is telling. The word was never flattering. It carried the sense that capital had become a camp with insiders, retainers, and protected routes to state power.

By the 1920s and 1930s, critics used zaibatsu to attack the tight bond between big business, militarization, and government procurement. After 1945, the Allied occupation made the word internationally familiar while attempting to dissolve the great combines. English borrowed it because conglomerate was too bland and cartel was too narrow. Zaibatsu kept the family tree and the political smell.

In modern English, zaibatsu usually refers to the prewar Japanese giants, though it is sometimes stretched metaphorically for any dynastic corporate bloc. The word remains useful because it names a structure, not just size. Some companies changed their legal shape. Power merely changed its tailoring.
