 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".During the subsequent Kyūshū Campaign in 1589, one of the Niwa clan retainers was again accused of collaboration with the enemy, and the clan was reduced further to a small 40,000 "koku" holding around Komatsu in Kaga Province.However, Toyotomi Hideyoshi was mercurial in his moods, and in response to Niwa Nagashige's efforts at the Siege of Odawara, his status was brought back to 120,000 "koku".
