A native of Mikawa Province in Japan, he lived during the Azuchi-Momoyama and Edo periods. Ieyasu promoted him from daimyo of the Ōtaki han (100 000 koku) to the Kuwana han (150 000 koku) as a reward for his service.[1] In addition, his son Honda Tadatomo became daimyo of Ōtaki.[2] In 1609, he retired, and his other son Tadamasa took over Kuwana. His grandson, Tadatoki, married the granddaughter of Tokugawa Ieyasu, Senhime. Despite his years of loyal service, Tadakatsu became increasingly estranged from the Tokugawa shogunate (bakufu) as it evolved from a military to a civilian political institution. This was a fate shared by many other warriors of the time, who were not able to make the conversion from the chaotic lifetime of warfare of the Sengoku period to the more stable peace of the Tokugawa shogunate.
