Question: what is zaibatsu and keiretsu?
Answer: Zaibatsu and Keiretsu are basically the same thing: Cartels, conglomerates, corporations. The term “zaibatsu” was used until Japan surrendered in WWII and was cleaned up halfheartedly by the US. The zaibatsu corporations were big actors in and the main profiteers of Japan's aggressive imperialist phase.
