Itō Kashitarō

Itō Kashitarō (January 1, 1835 – December 13, 1867) was a late Edo-period swordsman and strategist who served as military advisor and letters instructor for the Shinsengumi before leading a breakaway faction, the Goryō Eji (also called the Kōdaiji-tō). Born into a family of Hitachi Shitsuki domain retainers that fell into poverty, he studied in Mito before training at a Hokushin Ittō-ryū dojo in Edo, eventually marrying into the school and inheriting its leadership. Eloquent and devoted to the sonnō jōi (revere the emperor, expel the barbarians) cause, he joined the Shinsengumi in October 1864 through the introduction of fellow swordsman Tōdō Heisuke and rose to a position of trust under commander Kondō Isami. As ideological rifts widened between the pro-shogunate Shinsengumi and his own pro-imperial convictions, Itō and thirteen followers left the corps in April 1867 to form the Goryō Eji, charged with guarding the imperial mausolea. On December 13, 1867, three days after the assassination of Sakamoto Ryōma, he was lured to a banquet by Kondō and, on his way home, ambushed and killed by Shinsengumi swordsmen at Aburanokōji. He died at age 34. His swordsmanship, honed to the level of a dojo master in the Hokushin Ittō-ryū, underpinned both his standing within the Shinsengumi and his fatal confrontation with his former comrades. Posthumously honored with a court rank and enshrined at Yasukuni Shrine in 1932, he is remembered as a tragic idealist of the Bakumatsu era, often mentioned alongside Sakamoto Ryōma.
