Ōishi Susumu

Ōishi Susumu (personal name Tanetsugu; 1797 – December 29, 1863) was a swordsman of the late Edo to Bakumatsu period, a retainer of the Yanagawa domain in Chikugo Province who took Edo's fencing world by storm with a one-handed thrusting technique delivered from an extra-long 5-shaku-3-sun (roughly 160 cm) shinai, wielded by a man reportedly some 7 shaku (about 210 cm) tall. He founded his own school, the Ōishi Shinkage-ryū. Born in Miyabe village, Miike district, Chikugo (present-day Ōmuta, Fukuoka Prefecture), the eldest son of Ōishi Taneyuki, the Yanagawa domain's sword and spear instructor, he began training under his grandfather Tanemoto in the Shinkage-ryū and the Ōshima-ryū spear tradition from age four or five, receiving full transmission in the Shinkage-ryū in 1822. Around age eighteen he devised his signature one-handed thrust and began calling his style the Ōishi Shin'ei-ryū (later Ōishi Shinkage-ryū), developing a distinctive set of armor — including a thirteen-bar iron mask and bamboo body and forearm guards — suited to his aggressive fighting method. In 1832 he traveled to Edo and challenged dojo after dojo; his overwhelming reach and thrusting power stunned the capital's swordsmen. Chiba Shūsaku barely managed a draw against him, while Shirai Tōru reportedly defeated him; the following year he fought Otani Nobutomo to a standstill, earning the latter's high praise. Remembered alongside Otani Nobutomo and Shimada Toranosuke as one of the "Three Great Swordsmen of the Tenpō era," Ōishi is recalled as a singular figure in Bakumatsu-era swordsmanship for his unconventional reliance on an extra-long shinai and matching armor that upended the era's fencing conventions. He died in 1863 at age sixty-seven.
