Mitsuhashi Torazō (三橋虎蔵) was a Shingyōtō-ryū swordsman and a nephew of Iba Gunbei. The connection is genealogically pointed: the eighth Iba head, Hidenari, was himself born into the Mitsuhashi (三橋) house — a bakufu accounting family — before being adopted into the Iba line, so Torazō belonged to the headmaster’s natal family. Apart from his school, his kinship to the Iba house, and his Kōbusho appointment (in the ko-jūnin, 小十人, unit under Miyazaki Jirōdayū), the sources provide little further detail.
Mitsuhashi Torazō also appears in Odani’s disciple list, yet on the 1856 Kōbusho roster he is registered under Shingyōtō-ryū (心形刀流), so it may be that he was well-known, but more for his expertise in that other tradition.
