Yoshimasa served all three of the 'Unifiers' and received Okazaki castle in Mikawa province in 1590. He sent his son Yoshimune to Sekigahara with 3,000 men and was afterwards awarded a 320,000 koku fief in Chikugo province at Kurume. Like Hideyoshi, Yoshimasa came from the humblest of roots but gained a high position due to his natural talents.
