Horibe Yasubei

Horibe Yasubei (1670–1703) was a samurai who served the Akō Domain during the Genroku era of the Edo period. As one of the 47 Rōnin of Akō, he participated in the raid on Kira Kōzukenosuke and ended his life by seppuku as an embodiment of unwavering loyalty. He was also known as a martial artist through the Takadanobaba duel; including the circumstances by which he changed his name from Nakayama Yasubei to Horibe Yasubei, he is widely remembered as a samurai who embodied the chivalrous spirit of the early Edo period.

Yasubei was born as the son of Nakayama Yajirōemon of the Shibata Domain in Echigo Province (present-day Shibata City, Niigata Prefecture). From childhood he devoted himself to martial arts, gaining a reputation as a master swordsman in particular. After becoming a rōnin, he went to Edo and made his living while continuing to train in swordsmanship. In Genroku 7 (1694), according to a widely known account, he appeared gallantly at the scene of a duel at Takadanobaba, joined in the revenge of his kinsman Kanno Rokurōzaemon, and fought valiantly single-handedly against eighteen opponents. This exploit caught the eye of Horibe Yahei of Akō Domain, who adopted him as a son, after which he took the name "Horibe Yasubei."

After the lord of Akō Domain, Asano Takuminokami, committed an act of violence against Kira Kōzukenosuke within Edo Castle (Genroku 14, 1701) and suffered the misfortune of the domain's abolition, Yasubei, though now a rōnin, continued to communicate with his Akō comrades while waiting for an opportunity for revenge. In December of Genroku 15 (end of 1702), as a member of the 47 rōnin under the leadership of Ōishi Kuranosuke, he carried out the raid on the Kira residence and succeeded in killing Kira. In the following year, Genroku 16 (1703), in February, he committed seppuku by shogunal order. He was 34 years old.

In relation to the Japanese sword, Yasubei possessed deep knowledge of swordsmanship and blades. In the Takadanobaba duel as well, he wielded a Japanese sword, and his swordsmanship in repelling multiple opponents was passed down to later generations. Multiple swords are transmitted as Yasubei's beloved blades; the sword he actually used in the raid on the Kira residence, which he did not relinquish even after the surrender of Akō Castle, was particularly revered by later warriors as a "righteous blade." From the mid-Edo period onward, as subject matter in the Gishi-den and Kanadehon Chūshingura, Yasubei's renown as a master swordsman became widely known among the populace, and he continues to be spoken of as an important figure in the context of sword culture, embodying the symbolic significance of the Japanese sword and the loyalty of the samurai.
