Han system: History & Overview
Han (Japanese: 藩, "domain") is a Japanese historical term for the estate of a daimyo in the Edo period (1603–1868) and early Meiji period (1868–1912). Han or Bakufu-han (daimyo domain) served as a system of de facto administrative divisions of Japan alongside the de jure provinces until they were abolished in the 1870s.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Han system, one of the stronger structural bridges in this analysis connects Han system with History. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
