佐々成政
Komaru Castle was located on a small hill at the southern edge of the Fukui Plain. The inner bailey had stone ramparts and is thought to have had a donjon. A second and third bailey protected the inner citadel, and the whole was surrounded by moats and marsh. However, in 1581 Sassa Narimasa was awarded additional territories, and relocated to Etchū Province (current Toyama Prefecture), after leaving the unfinished Komaru Castle abandoned.
