Wakasa Province
In 1585, upon Nagahide's death, Nagashige received his father's fief of 1,230,000 "koku" (spanning Echizen, Wakasa, and parts of Kaga). During the Siege of Toyama against the forces of Sassa Narimasa, Hideyoshi accused the Niwa clan with collaboration, and seized most of their territories, leaving the clan with only Wakasa Province at 150,000 koku. This is believed to have been Hideyoshi's effort to reduce the Niwa clan's strength.
