- Japanese: 吉井友実 (Yoshii Tomozane)
Yoshii was a close friend of both Saigô Takamori and Ôkubo Toshimichi since they were young. In the 1860s, Yoshii became a central figure in the Seichûgumi, developed connections with Sakamoto Ryôma, and participated in the Battle of Toba-Fushimi.
Following the Meiji Restoration, Yoshii served in a number of government positions, including as a member of the first Privy Council, first Vice-Minister of the Imperial Household Ministry, and president of the Nippon Railway Company.
