How did the new rulers control the daimios?

The new rulers, particularly during the Edo period in Japan, exerted control over the daimiOS through a system known as "sankin-kotai," which required them to alternate their residence between their own domains and the shogun's capital, Edo. This not only restricted the daimiOS' power and resources but also allowed the shogunate to monitor them closely. Additionally, the rulers imposed strict regulations on the daimiOS' military capabilities and economic activities, ensuring loyalty and reducing the risk of rebellion. By controlling their wealth and mobility, the new rulers effectively maintained stability and centralized governance.
