Origins & Early Life

Yūki Hideyasu (結城 秀康; 1 March 1574 – 2 June 1607) was a Japanese samurai who lived during the Azuchi–Momoyama and early Edo periods. He was the daimyō of Fukui Domain in Echizen. Hideyasu was born as Tokugawa Ogimaru (徳川於義丸) in 1574, the second son of Tokugawa Ieyasu, by Lady Oman (also known as Lady Kogō), a handmaiden to his wife, Lady Tsukiyama. When Oman became pregnant, Ieyasu feared his wife's wrath, so he sheltered the girl in the home of his retainer Honda Shigetsugu, in Ofumi Village near Hamamatsu Castle, and it was there that Ogimaru and his brother were born. Oman is said to have given birth to twins, and that Ogimaru's brother succeeded Oman's father as priest of Chiryū Shrine in Mikawa Province.

Career & Major Achievements

The young Ogimaru was, for some reason, disliked by his father Ieyasu. It was not until age three that he met Ieyasu, and even that meeting, cold as it was, was not arranged by the father, but instead by Ogimaru's elder half-brother, Matsudaira Nobuyasu. After Oda Nobunaga demanded that Ieyasu order Nobuyasu's seppuku, Ogimaru would have been the next in line to inherit the Tokugawa headship by birth; however, as part of the peace negotiations following the Battle of Komaki-Nagakute, he was given in adoption (in reality as a hostage) to the childless Hashiba Hideyoshi in 1584. Coming of age while living with Hideyoshi, Ogimaru was given the name Hashiba Hideyasu, which combined the names of his adoptive father and biological father. He was also granted courtesy title of Mikawa-no-kami, and his Court rank was Senior Fifth Rank, Lower Grade, raised to Ukonoue-gon-shōshō and Senior Fourth Rank, Lower Grade in 1585 Hideyasu took part in his first campaign during the Kyūshū Campaign of 1587, leading the assault on Buzen-Iwaishi Castle.

Enduring Legacy & Impact

He also received honors for his distinction in the pacification of Hyūga Province. Hideyasu also took part in the Siege of Odawara (1590) and the Japanese invasions of Korea (1592–98). His successes in these campaigns earned him respect as an able field commander, despite his youth. However, in 1589, a natural son was born to Toyotomi Hideyoshi. Hideyoshi had adopted several promising candidates as heir over the years, and began to give these men in adoption to other great houses to avoid a potential conflict over the succession.
