SECTION II -- OVERVIEW
Born in 1548 (Tenbun 17) at Kurame in Nukata District, Mikawa Province (modern Okazaki City, Aichi Prefecture), the eldest son of Honda Tadataka.
His father fell in battle in 1549, and Tadakatsu was raised by his grandfather Tadatoyo. He entered the service of Matsudaira Motoyasu (the later Tokugawa Ieyasu) at thirteen, and thereafter served as the military core of Ieyasu's life.
He made his name at the Battle of Anegawa (1570), and took part in nearly all of the major Tokugawa engagements — Mikatagahara (1572), Nagashino (1575), Komaki-Nagakute (1584).
At the Kantō transfer of 1590 he was given Kazusa Ōtaki at 100,000 koku; after Sekigahara in 1600 he was moved to Ise Kuwana at 100,000 koku.
The Honda house continued through the Edo period as a fudai daimyō house, and Tadakatsu's line produced the lords of Okazaki, Kariya, Fukui, and others.
He died at Kuwana in 1610 (Keichō 15), aged sixty-three. No record of a serious wound suffered by Tadakatsu has been found in either contemporary or later compiled sources — the empirical basis of the later evaluation of 'fifty-seven battles unwounded.
SECTION III -- CHRONOLOGY
SECTION IV -- NOTABLE STATEMENTS
“Two things Ieyasu has more than he deserves: his Chinese helm and Honda Heihachi.”
SECTION V -- FIELD NOTES
[A]Standing Against a Great Army with a Small Force at Komaki-Nagakute
At Komaki-Nagakute in 1584, Tadakatsu is recorded in the Mikawa Monogatari and other sources as having ridden out with about five hundred horsemen to confront Hashiba Hideyoshi's main army of more than 80,000.
No actual engagement followed, but the anecdote of Hideyoshi having admired the orderly bearing of Tadakatsu's troop and held off from attack has been repeatedly retold as the emblem of Tadakatsu's martial prestige.
The numbers may carry exaggeration, but the fact of confronting a great army with a small force is corroborated in multiple contemporary records.
[B]Tonbogiri and a Life Unwounded
Tadakatsu's prized spear 'Tonbogiri' (Dragonfly-Cutter) was counted as one of the Three Great Spears of Japan.
It is a long-shafted spear, and the name comes from the tradition that a dragonfly that alighted on the blade was cut in two by the edge itself.
The Tonbogiri survives in records as a Honda-family heirloom and is held in several museums. The figure of 'fifty-seven battles unwounded' rests on Edo-period compiled materials such as the Bukō Zakki, and the specific number is a late-Edo accounting — but the fact that no record of Tadakatsu suffering a serious wound has been found in contemporary sources is broadly recognized among scholars.
SECTION VI -- LEGACY & IMPACT
Honda Tadakatsu, as one of the Tokugawa Four Heavenly Kings (Sakai Tadatsugu, Honda Tadakatsu, Sakakibara Yasumasa, Ii Naomasa), bore the military core of the founding process of the Tokugawa bakufu.
The term 'Four Heavenly Kings' itself is an honorific that formed in the Edo period, but the fact of the four men supporting Ieyasu's military body is corroborated in the sources.
Tadakatsu's line continued through the Edo period as a fudai daimyō house, and the various Honda branches were established across the country in Okazaki, Kariya, Fukui, Yamasaki, Nishibata, and other domains.
The Tonbogiri came to be recognized from the Edo period as one of the Three Great Spears of Japan, and is transmitted today as the emblem of the Honda house.
The Mikawa Monogatari (by Ōkubo Hikozaemon Tadataka) is the contemporary in-house record that transmits Tadakatsu's military career in the most detail, and stands as a foundational text of early-Tokugawa military history.
