Justo and his father fought through the turbulent age to secure their position as a "daimyō", he managed to acquire the Takatsuki Castle (in Takatsuki, Osaka) and participated in Ishiyama Hongan-ji War (1570-1580) under the warlord Oda Nobunaga and also under the daimyō Toyotomi Hideyoshi during his rule's earlier times, participating in the Battle of Yamazaki (1582), Battle of Shizugatake (1583) and Siege of Kagoshima (1587). During their domination of Takatsuki region he and his father pushed their policies as "kirishitan daimyōs". There were several of their subjects who converted to the faith under their guiding influence.

While several daimyō obeyed this order and renounced Roman Catholicism it was he who proclaimed that he would not give up his faith and would rather give up his land and all that he owned.
