Soga no Umako
As time went on, Sushun eventually became resentful of Umako's power, and wanted him deposed. It is said that one day, he saw a wild boar and proclaimed, "I want to kill Soga Umako like this wild boar". This angered Soga no Umako and, perhaps out of fear of being struck first, Umako had Sushun assassinated by in 592.
