Description
The Intellectual Swordsman: Sannan Keisuke
Sannan Keisuke, born in Tenpō 4 (1833), was an intellectually-oriented swordsman trained in the Hokushin Ittō-ryū. Said to have been born into the samurai stock of Sendai Domain, his refined education and dignified bearing distinguished him from Shieikan members of farming or lower-samurai origins. The Hokushin Ittō-ryū, founded by Chiba Shusaku, was the largest sword school of the Bakumatsu period, and Sannan joined the Shieikan group as an accomplished master of this lineage.
Rise to Shinsengumi General
Sannan participated in the Rōshigumi's journey to Kyoto in Bunkyū 3 (1863) and assumed the important position of General upon the Shinsengumi's formation. The General—operating under Director Kondō Isami and Vice Commander Hijikata Toshizō—oversaw the entire organization, a position earned through Sannan's intellect and administrative ability. While Sannan played a significant role in the Shinsengumi's discipline and organizational management, it is said that friction arose between him and Hijikata Toshizō's authoritarian methods of leadership.
A Wounded Arm and Shifting Position
From around Genji 1 (1864), Sannan is said to have suffered from some form of arm injury (details remain disputed). As his effectiveness as a swordsman declined, his standing within the organization shifted accordingly. It is said that differences emerged between the intellectual Sannan and the merit-driven Hijikata regarding the direction and future of the Shinsengumi.
His Beloved Blade: Sekishin Okimitsu
Sannan's treasured blade is said to have been the Sekishin Okimitsu (赤心沖光). The Yamato no Kami Yasusada (大和守安定), widely used among the Shinsengumi, is known as the blade worn by corps member Okita Sōji—a different sword often confused with Sannan's. The Sekishin Okimitsu was forged by a swordsmith of the late Edo period and is remembered as a blade capable of actual combat; Sannan bore this trusted sword into the fierce battles of the Shinsengumi.
Desertion and a Tragic End
In Keiō 1 (1865), Sannan deserted the Shinsengumi. Attempting to flee toward the Kusatsu area of Ōmi Province, he was pursued by Okita Sōji and brought back. The Shinsengumi's Kyokuchū Hattō (organizational code) strictly forbade desertion, and Sannan was ordered to commit seppuku. It was his sworn comrade Okita Sōji who served as his kaishakunin (second). He died at age thirty-three. The tragedy of Sannan Keisuke—a man of both intellect and martial skill—being brought to his end by the very code he himself had helped establish, stands as a poignant symbol of the harsh and unforgiving era in which Bakumatsu swordsmen lived.
