Description
Overview
"Toyotomi Kyodai!" is the 65th NHK Taiga Drama, airing from January 4, 2026 on NHK General. The script is by Hiroyuki Yatsu, with music by Hideaki Kimura, and lead actor Taiga Nakano plays Toyotomi Hidenaga. The drama features a star-studded cast: Sōsuke Ikematsu as Toyotomi Hideyoshi, Jun Oguri as Oda Nobunaga, Kōhei Matsushita as Tokugawa Ieyasu, and Kaname Jun as Akechi Mitsuhide.
Who Was Toyotomi Hidenaga?
Toyotomi Hidenaga (1540–1591) was the younger brother of Toyotomi Hideyoshi and served as his right hand throughout the unification of Japan. Known as the "Yamato-Daijō" (Great Counselor of Yamato), he was based in Yamato Province (modern Nara Prefecture) with Kōriyama Castle (Yamato-Kōriyama) as his stronghold. While Hideyoshi directed politics, diplomacy, and military affairs, Hidenaga handled the practical administration and maintained the loyalty of retainers—earning the reputation that "had Hidenaga lived longer, the Toyotomi clan's rule would have been secure."
Yamato Province and the Yamato Sword Tradition
Hidenaga's home province of Yamato (Nara Prefecture) was a major center of Japanese sword production, giving rise to the "Yamato-den" (Yamato tradition) of swordsmithing. Flourishing from the late Heian through the Kamakura period under the patronage of great Nara temples (Tōdai-ji, Kōfuku-ji, Kasuga Taisha), the Yamato tradition comprises five schools: Senjuin, Taima, Tegai, Hoshō, and Shikkake. That a senior Toyotomi retainer held the heart of this swordsmithing tradition adds historically rich context for Japanese sword enthusiasts.
Swords Associated with Hidenaga—Historical Records
Regarding Hidenaga and swords, the Honami Kōtoku Sword Catalogue (created by sword expert Honami Kōtoku) includes the entry "Sadamune, 1 shaku 1 sun, ascends from Yamato," which some researchers interpret as a reference to the Yamato-Daijō (Hidenaga). This blade may relate to the renowned Sōshū-den sword known as "Monoyoshi Sadamune," though no definitive historical sources confirm this, and it remains a scholarly theory. That Hidenaga was associated with numerous swords as a daimyo in the heart of Yamato-den country is beyond doubt.
The Sword Culture of Hidenaga's Era
The Tenshō-Bunroku period (1573–1591) when Hidenaga was active was a transitional era in sword history, with practical Sengoku-period blades coexisting alongside the ornamental swords of Momoyama culture. Under the Oda and Toyotomi regimes, swordsmiths received generous patronage, and both Nobunaga and Hideyoshi used the gifting of famous swords as political tools. Hidenaga too would have worn blades gifted by his brother and presented himself with appropriate swords in military and diplomatic settings.
Real Swords Featured
Yamato-den swords (Senjuin and Tegai schools)
Hidenaga's home province of Yamato (Nara Prefecture) was the birthplace of the Yamato sword tradition. Schools such as Senjuin and Tegai flourished from the late Heian through the Kamakura period in this very region, and the Yamato swordsmithing culture continued into the era when Hidenaga held the domain.
Possible connection to Monoyoshi Sadamune
The Honami Kōtoku Sword Catalogue contains the notation "Sadamune, ascends from Yamato," which some researchers interpret as referring to the Yamato-Daijō Hidenaga. Monoyoshi Sadamune is a celebrated tantō/wakizashi of the Sōshū tradition that later passed to the Tokugawa family. However, no definitive historical source confirms a direct connection to Hidenaga, and this remains a scholarly theory.
