In 1716, Yoshimune Tokugawa, who had been the lord of Kishu-han, became Shogun, and moved to the Edo castle. More than two hundred retainers of Kishu-han also immigrated to Edo to be retainers of the Tokugawa shogunate. Yoshimune assigned residences near the Edo castle especially to retainers close to him, while retainers close to his predecessor were obliged to move to outskirts of Edo. However, as seen in the example of Hakuseki Arai, some retainers resisted to these enforced immigrations.
