  • The lineage of Tsunahiro remains uncertain. One theory says he was a son of Gisuke while the other says he was adopted by Hirotsugu(広次).
  • His first smith name was Masahiro(正広) but he changed it to Tsunahiro when he was given the Kanji character of Tsuna”綱” from Hojo Ujitsuna(北条氏綱). While he was working under Hojo Ujitsuna in the Odawara area, he influenced the smith there a lot.
  • His name had been succeeded through many generations until the Meiji period. Among the generations, the smiths, who were active during the Keicho and the Manji era, left highly-qualified swords. Among them, the 5th generation Tsunahiro is considered to have been the teacher of KOTETSU(虎徹).
