Tosa Domain
According to Tani Tateki (1837–1911) of the Tosa Domain, Kondō was arrested under the alias of Okubo Yamato and executed by the new government (formed mostly by the samurai of the Chōshū han and the Satsuma han) as a direct result of being accused of the murder of Sakamoto Ryōma. Even after ex-Mimawarigumi member Imai Nobuo's confession in 1870, Tani insisted that Kondō was not falsely accused for Sakamoto's murder. (Even though the most accepted theory is that the mastermind of the assassination was Sasaki Tadasaburō of the Mimawarigumi, officially, it is still a mystery.)
