Burg Ōsaka
Ieyasu found fault with the opening ceremony of a temple built by Hideyori; it was as if he prayed for Ieyasu's death and the ruin of the Tokugawa clan. Ieyasu ordered Hideyori to leave Osaka Castle, but those in the castle refused and summoned samurai to gather within the castle. Then in 1614, Tokugawa besieged Osaka Castle against Hideyori.
