Following the Meiji Restoration in 1868, the new imperial government sought to dismantle the decentralized bakuhan system, which had granted daimyo significant autonomy over their han (domains) for over 250 years.12

The transition occurred in two primary stages:

Surrender of Domains (1869): The imperial government requested that the daimyo return their land patents to the emperor. Initially, the former daimyo were appointed as governors of these territories, which roughly corresponded to their previous domains.3
Abolition of the Han (1871): The government officially abolished the domains entirely, replacing them with a centralized prefecture system. This move effectively ended the daimyo's role as regional rulers. The former lords were subsequently converted into a pensioned nobility and required to reside in Tokyo, stripping them of their local administrative and military power.13

This administrative reorganization was a critical component of the broader effort to modernize Japan, unify the nation’s tax and monetary systems, and establish a centralized state capable of resisting foreign encroachment.2
