This study demonstrates the influence of academic disciplines in a “hanko" on the tenure of “rojus" who were councilors of the Edo shogunate. A hanko was a higher education facility for children of vassals in a feudal domain. This study employs negative binominal distribution analysis using 10 sets of panel data on hanko academic disciplines for a century from 1736 to 1835, in combination with 4 set of contemporary rojus's panel data.The results reveal that when the hanko in a roju's territory functioned as a hub and had high information centralities in the network, the roju's tenure was extended. The findings also indicate that the network established through the hanko's academic disciplines exerted a powerful influence on Edo society through information sharing in a feudal domain.
