Among these were Yamamoto Tonoma, Yamada Sanjuro, and his most beloved, Fuwa Bansaku (also Mansaku), who gained lasting renown for his beauty of body and spirit.

The following year, Hideyoshi lost his legitimate heir Tsurumatsu (who died before adulthood) and so gave Hidetsugu the position of Imperial Regent.

Controversially, Hideyoshi ordered the execution of Hidetsugu's entire family, including children, wives and mistresses, at Sanjogawara [jp].

The harshness and brutality of executing 39 women and children shocked Japanese society and alienated many daimyō from Toyotomi rule.

In a particularly tragic case, Hideyoshi refused to spare the life of Mogami Yoshiaki's 15-year-old daughter, who had only just arrived in Kyoto to become Hidetsugu's concubine and had not yet even met her husband-to-be.

Her death caused the powerful Mogami clan to zealously support Tokugawa Ieyasu in the Battle of Sekigahara against Toyotomi loyalist forces, five years later.
