Why was Tokugawa Ieyasu sent away as a hostage when he was young?

Tokugawa Ieyasu was sent away as a hostage in 1547 primarily due to the intense military adversity faced by his father, Matsudaira Hirotada. During this period of endemic civil strife in Japan, his father was involved in a network of shifting alliances that frequently drew him into battle. To navigate these pressures and secure his position, his father sent him to the powerful Imagawa clan in Sumpu.1

While en route, Ieyasu was captured by the rival Oda family and held for two years before eventually being released to the Imagawa. His time as a hostage was a result of the volatile political landscape of the era, where local warrior families often used such arrangements to manage alliances and survive the ongoing conflicts.21
