The castle saw three generations of rulers before being attacked and seized by the armies of Chûzan in [[1416]]. So-called "[[Warden of the North|wardens of the North]]" (''Hokuzan kanshu'') appointed by the royal government would continue to make their residence here for several centuries afterwards.

Hokuzan in general was characterized by wider spaces, or at least less dense settlement and population, than [[Nanzan]] and [[Chuzan|Chûzan]], the other kingdoms on the island at that time.
