Naoyoshi was a trusted retainer of Tokugawa Ieyasu. Toyotomi Hideyoshi is said to have been so impressed by him that he invited Naoyoshi to enter his service, to which the latter refused. At the outset of the Sekigahara Campaign he was sent to Kiyosu castle to alert the pro-Tokugawa lords in the area to the start of Ieyasu's movements.
